Short communication: psychrotrophic microorganism count in raw milk samples preserved with azidiol

The study aimed to evaluate the use of the azidiol® preservative for psychrotrophic microorganism count (PMC) in cooled raw milk. Two studies were carried out, one under controlled conditions (experiment 1) and the other under field conditions (experiment 2), in which samples of raw milk were taken with and without the use of the azidiol® preservative and analyzed at predefined times (0, 6, 12 and 24 hours -experiment 1) and at varying times (experiment 2). Analysis of variance and regression analysis using SAS were applied for data statistical analysis. Milk samples without azidiol®showed higher PMC with increasing time between sampling and analysis, while in samples preserved with azidiol®, this count remained constant. Samples of cooled raw milk intended for PMC should be collected in flasks containing the azidiol®preservative.(AU)

Effect of lactic acid bacteria preparations on calf fecal flora

This experiment was conducted to investigate the effects of lactic acid bacteria preparations on microbial diversity and community structure of calves. On days 1 and 7 of the trial period, feces were collected into sterile tubes and labeled (Day 1: control group D1DZ, experimental group D1SY, and Day 7: control group D7DZ, experimental group D7SY). Twenty Angus calves (150±10 kg) were selected and randomly divided into two groups of 10 calves each. The control group fed a basal diet. In addition to feeding the basal diet, the experimental group was given 15 mL lactobacillus preparation orally at 09:00 and 16:00 h every day. Calves were allowed free feeding and drinking water. All other feeding environments and management conditions remained consistent with the experiment lasting for seven days. At the end of the experiment, the fecal microflora of the calves was analyzed using 16S rRNA sequencing techniques. The 16S rRNA analysis data were processed using the Excel 2007 software and analyzed by the IBM SPSS statistical software (Statistical Analysis System, version 22). The Alpha diversity index analysis showed that the Chao and the Ace indices were significantly different after feeding supplemented with lactic acid bacteria. The PCA analysis showed that the fecal flora structure differed significantly after supplementation with the lactic acid bacteria preparation. Further analysis showed that the lactic acid bacteria increased Firmicutes, Patescibacteria, Rikenellaceae_RC9_gut_group, Clostridium_sensu_stricto_1, and prevotellaceae_UCG-003 in the feces. Therefore, we speculate that lactic acid bacteria preparations play an important role in animal production and are beneficial to the diversity of the fecal microflora of the calves.

Toxoplasma gondii in lactating animals: potential risk to milk consuming population in Khyber Pakhtunkhwa / Toxoplasma gondii em animais lactantes: risco potencial para população consumidora de leite em Khyber Pakhtunkhwa

Toxoplasma gondii is an intracellular zoonotic protozoan parasite usually infects human and animal worldwide. This study aimed to analyze the sero-prevalence of T. gondii in blood of lactating animals and human living in close proximity and also to detect Toxoplasma DNA in unpasteurized milk of the studied animals. A total of 233 blood and milk samples were collected from lactating animals, and 735 blood samples were taken from humans in District Upper Dir, Khyber Pakhtunkhwa, Pakistan. The blood samples were analyzed through ELISA while the milk samples were analyzed by PCR for the presence of T. gondii DNA. A standard questionnaire was introduced to collect the data from the participants. In animals, the reported sero-prevalence was 32.18% for IgM, 17.16% for IgG, and 6.4% for both IgM and IgG. The reported positivity for T. gondii DNA in milk was 14.44%, 34.8%, 20%, and 26% in sheep, goats, cows, and buffaloes, respectively. In the human blood samples, 9.8% were found positive for IgM and 11.2% for IgG while none of the samples was found positive for both IgM and IgG. Overall sero-prevalence reported in females was significantly higher than the male (p< 0.0001) were the significant risk factors associated with T. gondii infections in animals. In conclusion, T. gondii infection is prevalent in lactating animals and humans using their raw milk in the study area. It is suggested that raw milk should be considered as a vehicle for the transmission of T. gondii to humans. Proper pasteurization of milk is very useful in limiting the transmission of infection. Awareness and control programs should be implemented to prevent the infection.

Toxoplasma gondii é um protozoário parasita intracelular zoonótico que geralmente infecta humanos e animais em todo o mundo. Este estudo teve como objetivo analisar a soroprevalência de T. gondii no sangue de animais lactantes e humanos que vivem em proximidade, além de detectar o DNA de Toxoplasma no leite não pasteurizado dos indivíduos estudados. Um total de 233 amostras de sangue e leite foram coletadas de animais lactantes e 735 amostras de sangue foram coletadas de humanos no Distrito Upper Dir Khyber Pakhtunkhwa, no Paquistão. As amostras de sangue foram analisadas pelo método ELISA enquanto as amostras de leite foram analisadas por PCR para a presença de DNA de T. gondii. Um questionário padrão foi introduzido para coletar os dados dos participantes. Em animais, a soroprevalência relatada foi de 32,18% para IgM, 17,16% para IgG e 6,4% para IgM e IgG. A positividade relatada para DNA de T. gondii encontrada no leite foi de 14,44%, 34,8%, 20% e 26% em ovelhas, cabras, vacas e búfalas, respectivamente. Nas amostras de sangue humano, 9,8% foram consideradas positivas para IgM e 11,2% para IgG, enquanto nenhuma das amostras foi considerada positiva para IgM e IgG. A soroprevalência geral relatada em mulheres foi significativamente maior do que em homens (p < 0,05). Neste estudo, contato com gatos (p < 0,0001), hábitos alimentares (p < 0,0001), fonte de água para beber (p < 0,0001) e más condições de higiene (p < 0,0001) foram os fatores de risco significativos associados a infecções por T. gondii em animais. Em conclusão, a infecção por T. gondii é prevalecente em animais lactantes e humanos que utilizam leite cru, isto é, não-pasteurizado, na área de estudo. Sugere-se que o leite não-pasteurizado seja considerado um veículo de transmissão do T. gondii para humanos. A pasteurização adequada do leite é muito útil para limitar a transmissão de infecções. Programas de conscientização e controle devem ser implementados para prevenir a infecção.

In vitro evaluation of probiotic and technological properties of lactic acid bacteria isolated from artisanal cheese produced in the Serra Geral - Minas Gerais - Brazil / Avaliação in vitro de propriedades probióticas e tecnológicas de bactérias ácido-láticas isoladas de queijo artesanal da Serra Geral (MG)

O presente estudo avaliou o potencial probiótico in vitro de bactérias ácido-láticas (BAL) isoladas de queijo artesanal da Serra Geral (MG), com 14 e 21 dias de maturação, leite cru e pingo, utilizados em sua elaboração, e de bancadas de produção. As bactérias foram submetidas aos testes de antibiograma, à tolerância a ácido gástrico artificial e a sais biliares e ao antagonismo contra micro-organismos indicadores. Levilactobacillus brevis (Q521) e Lactococcus lactis (LLSG) apresentaram os melhores resultados e foram selecionados para a produção de leite fermentado. Apenas LLSG foi capaz de fermentar o leite. O produto apresentou qualidade microbiológica e físico-química adequada, exceto para os teores de proteína, segundo a legislação vigente para leites fermentados, demonstrando potencial tecnológico. A partir dos resultados apresentados, sugere-se que testes in vivo sejam realizados para que LLSG possa vir a ser utilizado como probiótico.

Avaliação da qualidade microbiológica de saladas de frutas comercializadas em Recife-PE / Evaluation of the microbiological quality of fruit salad commercialized in Recife-PE

Para auxiliar na mudança de vida e melhorar os hábitos alimentares, a população vem buscando integrar no seu cotidiano uma alimentação prática, saudável e nutritiva. Nesse contexto, a salada de frutas se torna um aliado por fornecer vitaminas e minerais importantes para a função básica do organismo, porém para tornar esse alimento seguro faz-se necessário um controle de sua qualidade. Por ser um alimento que contém um alto teor de água, sendo propício ao desenvolvimento de bactérias pode apresentar risco para a saúde do consumidor, caso não obtenham cuidados higiênicos-sanitários durante o seu processo produtivo. O presente estudo objetivou-se verificar a qualidade microbiológica das saladas de frutas prontas para consumo comercializadas na cidade do Recife-PE. Foram analisadas presença ou ausência de Salmonella sp. e a enumeração de coliformes termotolerantes a 45° C em vinte amostras do alimento coletado. A metodologia utilizada foi a descrita por Silva et al. (2017) e os resultados comparados com os parâmetros contidos na RDC nº 331 de 2019 e na Instrução Normativa nº 60 de 2019. Todas as amostras apresentaram ausência para Salmonella sp. em 25 g, mas para Coliformes termotolerantes foi detectada presença em 100% das amostras embora os valores estão dentro do que foi determinado na legislação. Conforme os resultados obtidos neste trabalho, as saladas de frutas estão aptas para consumo segundo as normas vigentes.(AU)

To help change their lives and improve eating habits, the population has been seeking to integrate into their daily lives a practical, healthy and nutritious diet. In this context, fruit salad becomes an ally for providing important vitamins and minerals for the basic function of the body, but to make this food safe it is necessary to control its quality. Because it is a food that presents a high water content, being prone to the development of bacteria and presenting a risk to the consumer's health, if hygienic-sanitary care is not taken during its production process. The present study aimed to verify the microbiological quality of ready-to-eat fruit salads sold in the city of Recife-PE. The presence or absence of Salmonella sp. and the enumeration of thermotolerant coliforms at 45°C in twenty samples of the food collected were analyzed. The methodology used was the one described by Silva et al. (2017) and the results were compared with the parameters contained in the RDC Nº 12 of 2001 and in the Normative Instruction Nº60 of 2019. All samples showed absence for Salmonella sp. in 25g, as for thermotolerant Coliforms was detected presence in 100% of products, but both values are within what was determined in the legislation. According to the results obtained in this study, the fruit salads are fit for consumption according to the current regulations.(AU)

Antagonistic activity of lactic acid bacteria isolated from Minas artisanal cheeses against Brucella abortus / Atividade antagonista de bactérias lácticas isoladas de queijos Minas artesanais contra Brucella abortus

This study aimed to evaluate methods for studying the in vitro antimicrobial activity of lactic acid bacteria (LAB) against Brucella abortus and to evaluate the antagonistic effect of LAB on the viability of this pathogen. A total of 18 LAB strains (Lactobacillus plantarum, n = 11; Pediococcus acidilactici, n = 1; Lactobacillus rhamnosus, n = 4; and Lactobacillus brevis,n = 2), isolated from Minas artisanal cheeses produced in three regions (Canastra, Campos das Vertentes, and Araxá) of Minas Gerais State, Brazil, were tested for their antimicrobial activity against B. abortus using three methods: spot-on-lawn, agar well diffusion assay, and antagonistic activity of the culture supernatants. None of the tested LAB strains could inhibit B. abortus in the spot-on-lawn and agar-well diffusion assays. The supernatants produced by LAB had an acidic pH, with intensity depending on bacterial growth and strain, and could inhibit the growth of B. abortus. In contrast, pH-neutralized (pH 7.0) LAB supernatants did not suppress the growth of B. abortus. The results showed that the best technique to study the in vitro antagonism of LAB against B. abortus was the antagonistic activity of culture supernatants. The growth of B. abortus may have been inhibited by acid production.(AU)

Este estudo teve como objetivo avaliar métodos de estudo in vitro da atividade antimicrobiana de bactérias lácticas contra Brucella abortus e avaliar o efeito antagônico das mesmas sobre a viabilidade deste patógeno. Um total de 18 amostras de bactérias lácteas (Lactobacillus plantarum, n = 11; Pediococcus acidilactici, n = 1; Lactobacillus rhamnosus, n = 4; e Lactobacillus brevis, n = 2), isoladas de exemplares de Queijo Minas Artesanal produzidos em três regiões (Canastra, Campos das Vertentes e Araxá) do estado de Minas Gerais, Brasil, foram testados quanto à sua atividade antimicrobiana contra B. abortus usando três métodos: spot-on-lawn, ensaio de difusão em poço e atividade antagonista de sobrenadante de cultura. Nenhuma das cepas testadas foi capaz de inibir B. abortus nos ensaios spot-on-lawm e de difusão em poço. Os sobrenadantes produzidos pelas bactérias lácteas apresentaram pH ácido, com intensidade dependente do crescimento bacteriano e da amostra, podendo inibir o crescimento de B. abortus. Em contraste, os sobrenadantes com pH neutralizado (pH 7,0) não inibiram o crescimento de B. abortus. Os resultados mostraram que a melhor técnica para estudar o antagonismo in vitro de bactérias lácteas contra B. abortus foi a atividade antagonista de sobrenadante de cultura. O crescimento de B. abortus pode ter sido inibido pela produção de ácido.(AU)

Avaliação microbiológica de queijos comercializados em feiras livres da baixada santista / Microbiological evaluation of cheese selled in free fairs in baixada santista

A qualidade microbiológica dos alimentos é de extrema importância a nível de saúde pública. Por isso, são necessárias análises para identificar possíveis contaminações e, a partir delas, estabelecer recomendações e medidas para garantia da segurança dos alimentos ofertados à população. A presença de Escherichia coli e coliformes totais nos alimentos indica condições de higiene insatisfatórias. Desta forma, no presente trabalho buscou-se avaliar a presença de E. coli e coliformes totais em queijos comercializados em feiras livres nos municípios da Baixada Santista, por meio de kit comercial COLItest ®. Verificou-se a presença de coliformes totais em nove amostras (100%). Sendo que cinco (55,5%) das amostras analisadas foram positivas para E. coli, indicando que os produtos vendidos na feira, sem controle de qualidade, possuem contaminações bacterianas que podem prejudicar a saúde dos consumidores.(AU)

The microbiological quality of food is extremely important in terms of public health. Therefore, analyzes are necessary to identify possible contaminations and based on them, establish recommendations and measures to guarantee the safety of food offered to the population. The presence of Escherichia coli and total coliforms in food indicates unsatisfactory hygiene conditions. In this way, the present work sought to evaluate the presence of E. coli and total coliforms in cheese sold in free fairs located in municipalities of Baixada Santista, through the commercial kit COLItest ®. The presence of total coliforms was verified in nine samples (100%). Five (55.5%) of the samples were positive for E. coli, indicating that the products sold at the fair, without quality control, have bacterial contamination that can harm the health of consumers.(AU)

Quality of refrigerated raw milk according to the bulk transport conditions

Technical regulations that determine milk quality standards in Brazil establish the minimum criteria that the processing industry's raw material must present. These rules can challenge the logistics sector (transport) to maintain adequate milk conservation levels. We aimed to evaluate the influence of bulk transport and storage conditions on refrigerated raw milk quality. The experiment was carried out in a dairy industry in Santa Catarina State. Information and samples of refrigerated raw milk were collected from dairy farms, from isothermal compartments of milk trucks, and from the industry's storage silo. These samples were submitted to microbiological analysis, somatic cell count(SCC), and physicochemical analysis. The results were evaluated by ANOVA and multivariate analysis (factor analysis). The transport of raw milk in bulk and the transfer of raw material to the industrial silo worsened the milk's microbiological quality (p < 0.0001) for standard plate count (SPC) and psychrotrophic microorganism count(PMC), without affecting, the physicochemical characteristics of the milk (p > 0.05). Poor hygienic conditions in milk storage rooms, in the refrigeration bulk tanks of the dairy farms, and during the transport, as well as the transport on longer routes, were related to higher SPC and psychrotrophic count while receiving milk by the dairy industry with higher temperatures was only associated with higher SPC.(AU)

Microbiological featuring of two neotropical fish species from the quilombola area of maranhão state, Brazil / Caracterização microbiológica de duas espécies de peixes neotropicais oriundas de área quilombola maranhense, Brasil

The aim of study is to feature the microbiological quality of two neotropical fish species from the quilombola area of Maranhão State, Brazil. In order to do so, 21 samples of Hoplerythrinus unitaeniatus and 21 samples of Cichlasoma bimaculatum were captured in flooded environment. Collected fish were euthanized in laboratory environment; muscle fragments were removed for microbiological analyses focused on enumerating molds and yeasts, viable strict and facultative mesophilic microorganisms and coagulase-positive staphylococci; on counting total and thermotolerant coliforms; and on investigating Escherichia coli and Salmonella sp. Microbiological results were compared to the Brazilian legislation, which establishes the list of microbiological standards for food products. Among the assessed fish, 9.52% were classified as non-acceptable for human consumption, based on the Salmonella parameter. Enumerated coagulase-positive staphylococci ranged from < 10 to 3.9 x 104 CFU/g; 9.52% of assessed fish were classified as having intermediate standard for human consumption, whereas 4.76% were classified as non-acceptable for such a purpose. E. coli counting ranged from 3.6 to > 1,100MPN/g; 4.76% of assessed fish were classified as having intermediate standard for human consumption, whereas 4.76% were classified as non-acceptable for such a purpose. Total and thermotolerant coliforms' counting and the enumeration of viable strict and facultative aerobic microorganisms, as well as of molds and yeasts, have evidenced high microbial population rates; this finding suggests poor hygienic conditions at capture site, contaminated raw material and risk of incidence of enteropathogens. This finding has evidenced imbalance in the investigated environment, as well as compromised aquatic biodiversity.(AU)

Objetivou-se caracterizar a qualidade microbiológica de duas espécies de peixes neotropicais oriundas de área qui-lombola maranhense, Brasil. Para isso, foram capturadas 21 amostras de Hoplerythrinus unitaeniatus e 21 amostras de Cichlasoma bimaculatum de ambiente alagável. No laboratório, os peixes foram eutanasiados, procedida a retirada dos fragmentos mus-culares e realizada as análises microbiológicas: enumeração de bolores e leveduras, micro-organismos mesófilos aeróbios estri-tos e facultativos viáveis e de estafilococos coagulase positiva, quantificação de coliformes totais e termotolerantes, pesquisa de Escherichia coli e Salmonella sp. Os resultados microbiológicos obtidos foram comparados com a legislação brasileira que estabelece a lista de padrões microbiológicos para alimentos. Dos peixes avaliados, 9,52% foram considerados inaceitáveis para consumo humano para o parâmetro Salmonella. A enumeração de estafilococos coagulase positivavariou de <10 a 3,9 x 104 UFC/g, sendo 9,52% dos peixes considerados com padrão intermediário e 4,76% inaceitáveis para consumo. A quanti-ficação de E. coli variou de 3,6 a >1.100 NMP/g, sendo 4,76% considerados com padrão intermediário e 4,76% inaceitáveis para consumo. A quantificação de coliformes totais e termotolerantes e a enumeração de micro-organismos aeróbios estritos e facultativos viáveis e bolores e leveduras revelou elevadas populações microbianas o que sugere más condições higiênicas do local de captura, matéria-prima contaminada e risco da presença de enteropatógenos, demonstrando desequilíbrio no ambiente estudado com comprometimento da biodiversidade aquática.(AU)

Análise microbiológica de sushi comercializado em Rio Branco, Acre / Microbiological analysis of sushi marketed in Rio Branco, Acre / Análisis microbiológico de sushi comercializado en Rio Branco, Acre

O Brasil é um dos países mais diversificados no ramo gastronômico oferecendo vários alimentos diferentes aos seus consumidores, com base nos próprios pratos típicos ou provenientes de outras culturas. O pescado trata-se de um alimento perecível que necessita de atenções especiais em seu processamento. Falhas nas condições higiênico-sanitárias, associadas com a não cocção do alimento, podem ocasionar em uma contaminação e proliferação de bactérias, o que leva à uma grande preocupação a nível de saúde pública. O estudo analisou os aspectos microbiológicos de sushi comercializado na cidade de Rio Branco ­ Acre verificando os parâmetros de qualidade e as condições higiênicas sanitárias, comparando os resultados obtidos com a legislação vigente estabelecida pela ANVISA. Foram escolhidos 5 estabelecimentos aleatoriamente, sendo escolhidas 3 amostras de sushis do tipo niguiri de cada. As análises microbiológicas incluíram coliformes totais e coliformes termotolerantes utilizando a técnica dos tubos multiplos e a técnica de semeadura por profundidade para mesófilos e Salmonella. Constatou-se que todas as amostras tiveram um crescimento bacteriano e presença sugestiva de Salmonella, tornando o alimento impróprio para o consumo e mostrando uma falha nas condições higiênico- sanitária ao qual o sushi é processado e armazenado. É necessário maior fiscalização dos órgãos responsáveis e cuidado dos estabelecimentos que vendem sushi na cidade de Rio Branco, para que o produto vendido seja de boa qualidade e não cause malefícios a saúde de quem o consome.(AU)

Brazil is one of the most diversified countries in the gastronomic field, offering several different foods to its consumers, based on typical dishes or from other cultures. Fish is a perishable food that requires special attention in its processing. Failures in hygienic-sanitary conditions, coupled with the consumption of undercooked food, can lead to contamination and the proliferation of bacteria, which raises significant concerns regarding public health. The study analyzed the microbiological aspects of sushi sold in the city of Rio Branco - Acre, verifying the quality parameters and the hygienic sanitary conditions, comparing the obtained results with the current legislation established by ANVISA. Five establishments were randomly selected, and three samples of nigiri sushi were chosen from each establishment. The microbiological analysis included total coliforms and thermotolerant coliforms using the multiple tube technique, as well as depth seeding technique for mesophiles and Salmonella. It was found that all samples exhibited bacterial growth and suggested the presence of Salmonella, rendering the food unsuitable for consumption and indicating a failure in the hygienic-sanitary conditions under which the sushi was processed and stored. Greater inspection by the responsible authorities and improved care by establishments selling sushi in the city of Rio Branco are necessary to ensure that the product sold is of good quality and does not pose harm to the health of consumers.(AU)

Performance, Gut Integrity, Enterobacteria Content in Ceca of Broiler Fed Different Eubiotic Additives

An experiment was carried out to study the effect of different eubiotics on productive characteristics, intestinal integrity, as well as the content of enterobacteria in the cecum of broiler chickens. A completely randomized design with five treatments and 8 replicates of 25 birds each was used. In total 1000 mixed broiler chickens from Ross308 strain, one day old were obtained from a commercial hatchery. The birds were housed on concrete floors in a conventional house. A sorghum+soybean meal control diet was used, to which the additives under study were added. The treatments were distributed as follows: T1 = Control diet without antibiotic or eubiotic; T2 = T1 + bacteriophages; T3 = T1 + antibiotic; T4 = T1 + probiotic; T5 = T1 + symbiotic. The results obtained at 49 days of age for weight gain and feed conversion rate improved (p<0.05) with the addition of the antibiotic and eubiotics. A lower (p<0.05) intestinal density was observed with the probiotic. The height, width, and area of villi in duodenum was higher (p<0.05) when antibiotic and eubiotics were included. In the histological score, in duodenum, the antibiotic and eubiotics resulted with a higher score (p<0.05), associated to a physiological and controlled inflammation response that allowed improving productivity. Finally, the relative expression of enterobacteria, such as Lactobacillus salivarius, allowed associating positive changes in the microbiome and better productive parameters when including the symbiotic, with comparable results to the antibiotic when including the eubiotics.(AU)

High Genetic Similarity Among Salmonella Heidelberg Isolated from Poultry Farms, Wild Animals, Beef, Poultry and Pork Meat, and Humans in Brazil

Salmonellosis is an important gastrointestinal infection in humans and cause of foodborne outbreaks in the world. In this context, molecular characterization is essential to understand how the strains circulate. The aim of this study was to evaluate the genotypic distribution of S. Heidelberg according to the source of isolation. The genetic relatedness of the S. Heidelberg isolates was determined by pulsed-field gel electrophoresis (PFGE). The most prevalent pulsotypes of cluster A were BRJF6X01.006 (27/95 = 28,42%) related between 1995 and 2011 in broilers, poultry meat and poultry farms, meat product and human, and BRJF6X01.001 (21/95 = 22,10%) related between 2011 and 2017 in wild animals, broilers, poultry meat, poultry farms, meat product, animal feed, and pork meat. The pulsotype BRJF6X01.001 shows a high distribution in the environmental and productive chain. The degree of similarity between pulsotypes BRJF6X01.006 and BRJF6X01.001 is 88%. To ensure the safety of human and animal health, holistic approaches, including surveillance of Salmonella throughout the environment and in the production chain, together with control measures, are critical. As transmission of Salmonella from food producing animals to wildlife and to the environment is considered potential public health problem, information on the survival and persistence of Salmonella in the environment and in potential reservoirs is of considerable importance.(AU)

Cellulolytic activity of anaerobic facultative fungi from the digestive tract of sheep fed with banana leaf hay / Atividade celulolítica de fungos aeróbios facultativos do trato digestório de ovinos alimentados com feno da folha de bananeira

The addition of cellulolytic fungi, or their enzymes, in diets containing high levels of fiber are promising strategy for improving the performance. In this study, the aims were to select cellulolytic fungi from the digestive tract of sheep fed different concentrations of banana leaf hay. Thirty lambs raised in a feedlot were evaluated, distributed in a completely randomized design, with diets containing 0, 125, 250, 375, or 500 g/Kg of dry matter and six replications. Approximately 15 mL of ruminal fluid and swabs from the rectal ampulla were collected. The cultures were carried out in a medium containing microcrystalline cellulose (C medium). The mycelial fungi isolates were identified through the microculture technique. Among the fungi from the ruminal fluid, 23 isolates corresponded to the genus Aspergillus and three to Paecilomyces spp. Among the isolates from the rectal ampulla, seven were A. spp., and three were P. spp. The A. genus predominated among the isolates from both evaluated sites (p <0.05). Fragments of these fungi were inoculated in triplicate in medium C at 37 °C and the cellulolytic activity index (CAI) was determined after 24, 48, and 72 hours of incubation. There was no difference in the CAI of Aspergillus spp. from animals fed different diets or of different evaluated sites (P > 0.05). However, 22 isolates of Aspergillus spp. and three of Paecilomyces spp. showed a CAI > 1, indicating biotechnological potential for cellulase production. These selected isolates could be selected for the elaboration of microbial additives in ruminant diets.(AU)

A adição de fungos celulolíticos, ou suas enzimas, em dietas contendo elevados teores de fibras são estratégias pro-missoras para melhorar o desempenho. Neste estudo os objetivos foram selecionar fungos celulolíticos do trato digestório de ovinos alimentados com diferentes concentrações do feno da folha da bananeira (FBH). Foram avaliados 30 borregos criados em sistema intensivo, distribuídos em delineamento inteiramente ao acaso, com cinco dietas contendo 0, 125, 250, 375 ou 500 g/KG de matéria seca em seis repetições. Foram coletados aproximadamente 15 mL de fluido ruminal e swabs da ampola retal. Os cultivos foram realizados em meio de cultura contendo celulose microcristalina (meio C). Os fungos micelianos foram identificados após a técnica de microcultivo. Entre os fungos provenientes do fluido ruminal, 23 isolados corresponderam ao gênero Aspergillus e três a Paecilomyces spp.. Foram identificados nas fezes dos animais sete Aspergillus spp. e três Paecilomyces spp.. O gênero Aspergillus predominou entre os isolados de ambos os sítios avaliados (p =0,013). Fragmentos desses fungos foram inoculados em triplicada em meio C a 37 °C e determinou-se o índice de atividade celulolítica(IAC) após 24, 48 e 72 horas de incubação. Não houve diferença entre CAI de isolados de Aspergillus spp. provenientes dos animais em diferentes dietas ou sítios avaliados (P > 0.05). Entretanto, 22 isolados de Aspergillus spp. e três de Paecilomyces spp. apresentaram IAC >1, indicando potencial biotecnológico para produção de celulases.(AU)

Cultivo associado de Leuconostoc mesenteroides lb10. 4 e Lactococcus lactis l4a8: propriedades antimicrobianas e potencial aplicação / Associated culture of Leuconostoc mesenteroides lb10. 4 and Lactococcus lactis l4a8: antimicrobial properties and potential application / Cultivo asociado de Leuconostoc mesenteroides lb10. 4 y Lactococcus lactis l4a8: propiedades antimicrobianas y aplicación potencial

O interesse por produtos lácteos funcionais tem motivado o estudo e a prospecção de novas bactérias lácticas. Neste contexto o objetivo deste trabalho foi explorar a potencial associação de Leuconostoc mesenteroides LB10.4 e Lactococcus lactis L4A8 isolados de leite de búfala e identificar aplicações em matriz alimentar. Foram realizados testes de atividade antimicrobiana, influência das bacteriocinas e avaliação da eficiência das bactérias ácido lácticas (BAL) individualmente e associadas frente a espécie de Listeria monocytogenes ATCC 7644 aplicadas em caldo Tryptic Soy Broth e em matriz láctea. Na avaliação da atividade antimicrobiana, Leuconostoc mesenteroides LB 10.4 e Lactococcus lactis L4A8 foram capazes de inibir Staphylococcus aureus ATCC 25923 e Listeria monocytogenes ATCC 7644 com halos de inibição variando de 8 a 16 mm e 6 a 18 mm, respectivamente, pelos dois métodos testados. Na avaliação do efeito das bacteriocinas, os resultados demonstraram melhor controle inibitório dos patógenos pela nisina nas concentrações de 1% e 2%, com halos de inibição entre 14 a 24 mm. A avaliação da eficiência das BAL individualmente e associadas frente a espécie de Listeria monocytogenes ATCC 7644, demonstrou que os isolados em associação são capazes de inibir com mais efetividade a bactéria patogênica, sendo observada uma redução na contagem de L. monocytogenes de 2,67x107 UFC/g para 1,35x104 UFC/g após 240 horas, em matriz alimentar.

The interest in functional dairy products has motivated the study and prospection of new lactic bacteria. In this context, the aim of this study was to explore the potential association of Leuconostoc mesenteroides LB10.4 and Lactococcus lactis L4A8 isolated from buffalo milk and to identify applications in food matrix. Tests of antimicrobial activity, influence of bacteriocins and evaluation of the efficiency of lactic acid bacteria (LAB) individually and associated against the species of Listeria monocytogenes ATCC 7644 applied in Tryptic Soy Broth and in milk matrix were performed. In the evaluation of antimicrobial activity, Leuconostoc mesenteroides LB 10.4 and Lactococcus lactis L4A8 were able to inhibit Staphylococcus aureus ATCC 25923 and Listeria monocytogenes ATCC 7644 with inhibition halos ranging from 8 to 16 mm and 6 to 18 mm, respectively, by the two methods tested. In evaluating the effect of bacteriocins, the results showed better inhibitory control of pathogens by nisin at concentrations of 1% and 2%, with inhibition halos between 14 and 24 mm. The evaluation of the efficiency of LAB individually and associated against the species of Listeria monocytogenes ATCC 7644, showed that the isolates in association are able to more effectively inhibit the pathogenic bacteria, with a reduction in the L. monocytogenes count of 2.67x107 CFU /g to 1.35x104 CFU/g after 240 hours, in food matrix. The lactic acid bacteria Leuconostoc mesenteroides LB10.4 and Lactococcus lactis L4A8 showed promising characteristics regarding their inhibitory potential, not being inhibited by pediocin. With these results, attract attention the importance of studying buffalo milk as a source of new candid ates of autochthonous lactic acid bacteria for application in food.(AU)

Amazonian soil fungi are efficient degraders of glyphosate herbicide; novel isolates of Penicillium, Aspergillus, and Trichoderma / Os fungos do solo amazônico são degradadores eficientes do herbicida glifosato; novos isolados de Penicillium, Aspergillus e Trichoderma

Pesticide residues that contaminate the environment circulate within the hydrological cycle can accumulate within the food chain and cause problems to both environmental and human health. Microbes, however, are well known for their metabolic versatility and the ability to degrade chemically stable substances, including recalcitrant xenobiotics. The current study focused on bio-prospecting within Amazonian rainforest soils to find novel strains fungi capable of efficiently degrading the agriculturally and environmentally ubiquitous herbicide, glyphosate. Of 50 fungal strains isolated (using culture media supplemented with glyphosate as the sole carbon-substrate), the majority were Penicillium strains (60%) and the others were Aspergillus and Trichoderma strains (26 and 8%, respectively). All 50 fungal isolates could use glyphosate as a phosphorous source. Eight of these isolates grew better on glyphosate-supplemented media than on regular Czapek Dox medium. LC-MS revealed that glyphosate degradation by Penicillium 4A21 resulted in sarcosine and aminomethylphosphonic acid.

Resíduos de agrotóxicos que contaminam o meio ambiente circulam no ciclo hidrológico, podendo se acumular na cadeia alimentar e causar problemas tanto à saúde ambiental quanto humana. Por sua vez, microrganismos são bem conhecidos por sua versatilidade metabólica e capacidade de degradar substâncias quimicamente estáveis, incluindo xenobióticos recalcitrantes. O estudo atual se concentrou na bioprospecção nos solos da floresta amazônica para encontrar novas linhagens de fungos capazes de degradar com eficiência o herbicida onipresente na agricultura e no meio ambiente, o glifosato. Entre os 50 fungos isolados (usando meio de cultura suplementado com glifosato como única fonte de carbono), a maioria eram isolados do gênero Penicillium (60%) e os outros eram isolados de Aspergillus e Trichoderma (26 e 8%, respectivamente). Todos os 50 isolados de fungos foram capazes de usar glifosato como fonte de fósforo. Oito desses isolados cresceram melhor em meio suplementado com glifosato do que em meio Czapek Dox regular. LC-MS revelou que a degradação do glifosato por Penicillium 4A21 resultou nos metabólitos sarcosina e ácido aminometilfosfônico.

Qualidade microbiológica de hambúrgueres comercializados no município do Rio de Janeiro / Microbiological quality of hamburgers commercialized in the municipality of Rio de Janeiro

O hambúrguer é um produto cárneo moldado, com maior risco de contaminação microbiana pelo fato de ser preparado com carne moída que apresenta maior superfície de exposição, além de ser muito manipulado e consumido, muitas vezes, mal-passado. O objetivo do presente estudo foi avaliar a qualidade microbiológica de hambúrgueres industriais comercializados no município do Rio de Janeiro/RJ, bem como, verificar as condições higiênicosanitárias dos locais de comercialização. Foram coletadas 12 amostras de hambúrguer, de oito marcas comerciais, comercializados em três diferentes supermercados. Durante a coleta das amostras foi realizada uma avaliação visual das condições higiênicas da comercialização. Após obtenção, as amostras foram encaminhadas para o Laboratório de Controle Microbiológico de Alimentos da Universidade Castelo Branco (UCB), para realização das análises microbiológicas. De acordo com os resultados das avaliações higiênicosanitárias dos locais onde as amostras de hambúrguer foram obtidas, observou-se 20%, 60% e 20% de não conformidades nos supermercados I, II e III, respectivamente, devido falhas na organização da gôndola, no acondicionamento do produto e/ou no controle da temperatura de comercialização. Resultados em não conformidade com o padrão microbiológico vigente foram observados em 16,67%, 66,67% e 8,33% das amostras para a contagem de Bactérias Heterotróficas Aeróbias Mesófilas, Estafilococos coagulase positiva e E. coli, respectivamente. A presença de Unidades Formadoras de Colônias típicas de Salmonella spp foi verificada em 41,67% das amostras. Os resultados demonstraram que os hambúrgueres comercializados em três supermercados do município do Rio de Janeiro/RJ estavam impróprios para o consumo podendo representar risco à saúde dos consumidores.(AU)

The hamburger is a molded meat product with a greater risk of microbial contamination because it is prepared with ground meat, which has a greater contact surface. In addition, it is very manipulated and often consumed medium rare. The objective of the present study was to evaluate the microbiological quality of industrial hamburgers sold in Rio de Janeiro/RJ and verify the hygienic-sanitary conditions of the commercialization places. Twelve hamburger samples were collected, from eight commercial brands, and sold in three different supermarkets. During the collection of the samples, a visual evaluation of the hygienic conditions of the commercialization was carried out. After obtaining, the samples were sent to the Laboratory of Microbiological Control of Food at Universidade Castelo Branco (UCB), for microbiological analysis. According to the results of the hygienicsanitary evaluations of the places where the hamburger samples were obtained, 20%, 60%, and 20% of non-conformities were observed in supermarkets I, II, and III, respectively. The non-conformities were due to failures in the organization of the shelf, in the packaging of the product, and/or in the control of the commercialization temperature. Results that did not comply with the current microbiological standard were observed in 16.67%, 66.67%, and 8.33% of the samples for the counting of Mesophilic Aerobic Heterotrophic Bacteria, Coagulase Positive Staphylococci, and E. coli, respectively. The presence of typical Colony Forming Units of Salmonella spp was verified in 41.67% of the samples. The results showed that the hamburgers sold in three supermarkets in Rio de Janeiro/RJ were unfit for consumption and could pose a risk to consumers' health.(AU)

Physicochemical and microbiological quality of refrigerated raw bovine milk commercialized in Presidente Médici, Rondônia state, Western Amazon, Brazil / Qualidade físico-química e microbiológica de leite bovino cru refrigerado comercializado em Presidente Médici, estado de Rondônia, Amazônia Ocidental, Brasil

The aimed of the study was to evaluate the quality of raw milk from some suppliers in rural and urban areas and to test the hypothesis that it is unsafe for direct consumption. The study was conducted with suppliers in rural and urban areas in Presidente Médici municipality, Rondônia state. The method of the Ministério da Agricultura, Pecuária e Abastecimento (MAPA), was used, which consists of titrating a portion of the sample with a sodium hydroxide solution of known concentration, using phenolphthalein as an indicator. According to Brazilian legislation and literature, stability of Alizarol, foreign substances, Chloride, Hypochlorite, Hydrogen Peroxide and Colostrum were analyzed. Microbiological analysis, standard plate count (SPC) and quantification of thermotolerant coliforms were also performed using the most probable number (MPN) technique. Values above the limits established by legislation were found, mainly for temperature and titleable acidity, in addition to stability results against Alizarol and the presence of colostrum. There were high microbial contents with regard to SPC, and, in this case, the presence of pathogenic microorganisms cannot be disregarded. The presence of thermotolerant coliforms may indicate probable contact of milk with feces. Therefore, it is considered that the samples analyzed here are not safe for ingestion in the raw form.(AU)

O objetivo do estudo foi avaliar a qualidade do leite cru de alguns fornecedores da zona rural e urbana e tes-tar a hipótese de que não são seguros para o consumo direto. O estudo foi conduzido em fornecedores da zona rural e urbana do município de Presidente Médici, estado de Rondônia. Empregou-se o método do Ministério da Agricultura Pecuária e Abastecimento (MAPA), que consiste na titulação de uma porção da amostra por uma solução hidróxido de sódio de concentração conhecida, utilizando como indicador a fenolftaleína. Conforme a legislação brasileira e a lite-ratura, foram analisados estabilidade do Alizarol, substâncias estranhas, Cloreto, Hipoclorito, peróxido de Hidrogênio e Colostro. Foram realizadas também análises microbiológicas, contagem Padrão em Placa (CPP) e quantificação dos coliformes termotolerantes através da técnica do número mais provável (NMP). Foram encontrados valores acima dos limites estabelecidos pela legislação, principalmente para temperatura e acidez titulável, além dos resultados de estabili-dade frente ao Alizarol e da presença de colostro. Houve altos teores microbianos no que se refere à CPP, e, nesse caso, a presença de microrganismos patogênicos não pode ser desconsiderada. A presença de coliformes termotolerantes pode indicar provável contato do leite com fezes. Portanto, considera-se que as amostras aqui analisadas não são seguras para ingestão na forma crua.(AU)

Efficiency of chemical preservatives used in raw milk samples for bacterial counts by flow cytometry

The objective of this study was to evaluate and compare two chemical preservatives in terms of their sample preservation capabilities, considering the individual bacterial count (IBC) and time and temperature variables. Samples were collected in expansion tanks in three commercial dairy farms located in the northwest of Rio Grande do Sul, characterized as G1: low IBC values, G2: average IBC values, and G3: high IBC values. The tanks were stored at three different temperatures (4, 10, and 25 °C) for 14 d. Samples supplemented with the preservative Azilat in G1 (lower IBC group) exhibited the best results at a temperature of 4 °C, whereas for G2 and G3, the results showed no statistically significant difference between temperatures 4 and 10 °C. The temperature 25 °C exhibited the worst results. For samples preserved with Azidiol, regardless of the studied group (G1, G2, and G3), the temperatures of 4 and 10 °C did not present a significant difference regarding the preservation of the samples, with the temperature of 25 °C exhibiting the worst results. Azilat was effective in keeping the samples conserved when they presented low IBC, being able to fluctuate with the increase in IBC and temperature variation. Azidiol was effective regardless of the initial IBC level.

Aspergilose em calopsita (Nymphicus hollandicus) / Aspergillosis in a cockatiel (Nymphicus hollandicus)

Background: Aspergillosis is a defiance in avian medicine, however between of Aspergillus species, 3 are the most frequently observed (A. flavus, A. fumigatus and A. niger). Psittaciformes present medical conditions related to the 3 species, however A. fumigatus is the most observed. The defiance of the diagnosis is related to fungus characteristics (they are saprophytic in healthy birds), the clinical signs and lesions, which are common to various respiratory diseases, and the difficulty to access specific diagnostic methods. Thus, we report a case of aspergillosis in a cockatiel, whose clinical diagnosis was confirmed by fungal culture of cloacal swab, and treatment with a fungistatic drug. Case: A female cockatiel, 2-month-old, not dewormed, presented diarrhea, sneezing and difficulty to gain weight, although eating well (extruded feed and supplementation with fruits and vegetables). At a clinical examination revealed body score (BCS) of 3 (scale 1 at 5), cloacal temperature (CT) of 40 ºC, dilated nostrils and edema in the left eye region associated to evident hyperemia. Due to it has lived with another animal, was inferred that was hypovitaminosis A, by food dispute and/ or dominance, or endoparasitosis, being prescribed vitamin A supplementation and deworming with ivermectin. The bird returned 15 days later, showing maintenance of weight loss, BCS 2, ruffled feathers and areas suggestive of apteriolysis in both forelimbs, respiratory difficulty and pulmonary and cranial air sacs rales, in addition presented wound in the pygostyle region and ventus, occasioned by attempted attack of a dog, and aggravated by self-mutilation. Due the worsening of the clinical condition, an oral cavity and cloacal swabs were collected to bacteriological and fungal culture. As treatment was prescribed: a natural tranquilizer, seeking to control the self-mutilation; doxycycline oral suspension, to treat a probable bacterial respiratory infection; and oral itraconazole suspension, manipulated and with a dose calculated by allometric scaling, being placed an elizabethan collar in order to prevent biting the pygostyle and ventus. With a positive result of the cloacal swab fungal culture for A. fumigatus, the doxycycline was discontinued. After the first 30 days of treatment with itraconazole, the patient returns to alert, weighing 95 g, BCS 3, with absence of respiratory signs and with signs of recent molting process. New swabs (oral and cloacal) were collected for repetition of bacterial and fungal cultures, being maintained the treatment with itraconazole. The results of both bacterial and fungal cultures were negative. At the end of the treatment with itraconazole, the patient returns demonstrating weight gain, EEC 3, CT of 42ºC, uniform feather coverage and absence of any respiratory sign, being released by the clinician. Discussion: A preponderant factor in the treatment of various respiratory diseases in birds is the diagnosis, since many of diseases present the same clinical signs. Thus, the use of fungal culture was essential to determine the origin of the signs. Still, even with an accurate diagnosis, the clinician often comes up against the difficulty of treatment, especially in cases of mycotic infections. The knowledge about the best drug, considering the pharmacology, as well as the availability of concentrations and dosages marketed, in addition to the long period of treatment, can difficult or make impossible the case resolution. In fact, this is confirmed by the literature, where the most of aspergillosis diagnosis are post mortem, resulting from the delay in seeking veterinary care or in the administration of ineffective drugs. Thus, with this report, we sought to present a diagnostic tool, sometimes neglected, and a compilation with the main drugs and their effectiveness in the treatment of aspergillosis in Psittaciformes.
