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)

Ascaridia galli: A report of erratic migration in eggs for human consumption in Bucaramanga, Colombia - case report / Ascaridia galli: Um relatório de migração errática em ovos para consumo humano em Bucaramanga, Colômbia - relato de caso

This case report describes how an erratic specimen of Ascaridia galli in the adult phase was recovered in an unusual way from a hen's egg intended for human consumption. Although the literature on similar events is limited, this appears to be the first case reported in Bucaramanga, Colombia. The parasite was identified directly under a light microscope as an adult female A. galli, 6.5-cm long with 3 trilobed lips. In addition, the remaining eggs of the same group were examined to determine if there were more cases of erratic migration in that same batch. This nematode can cause various pathological conditions, including enteritis, hemorrhage, diarrhea, anemia, weakness, and emaciation, that can lead to huge economic and production losses in the poultry industry.

Este relato de caso descreve como um exemplar errático de Ascaridia galli na fase adulta foi recuperado de uma forma incomum em um ovo de galinha destinado ao consumo humano. Embora a literatura sobre eventos similares seja limitada, este parece ser o primeiro caso relatado em Bucaramanga, Colômbia. O parasita foi identificado diretamente sob um microscópio leve como uma fêmea adulta A. galli, com 6,5 cm de comprimento e 3 lábios trilobados. Além disso, os ovos restantes do mesmo grupo foram examinados para determinar se existiam mais casos de migração errática nesse mesmo lote. Este nemátodo pode causar várias condições patológicas, incluindo enterite, hemorragia, diarréia, anemia, fraqueza e emaciação, que podem levar a enormes perdas econômicas e de produção na indústria avícola.

Esporotricose em felinos domésticos: revisão de literatura / Sporotrichosis in domestic felines: literature review

A Esporotricose é uma micose subcutânea de caráter zoonótico causada pelo fungo Sporothrix schenckii que habita o solo, palhas, vegetais e também madeiras, podendo ser transmitido por meio de materiais contaminados, como farpas ou espinhos. Contudo os animais infectados e em especial os gatos, também transmitem a doença, por meio de arranhões, mordidas e contato direto com pele lesionada. Nos mamíferos, o quadro clínico apresenta-se na forma crônica ou aguda com o surgimento de lesões cutâneas. A doença é considerada um problema de saúde pública, pois afeta a população de áreas endêmicas. O presente trabalho foi delineado para analisar a manifestação da doença em gatos domésticos, revisando sinais clínicos, diagnóstico, prevenção, tratamento e também faz um alerta para a sua importância em saúde pública.(AU)

Sporotrichosis is a zoonotic subcutaneous mycosis caused by the fungus Sporothrix schenckii that inhabits the soil, straw, vegetables and also wood, and can be transmitted through contaminated materials, such as splinters or thorns. However, infected animals, and especially cats, also transmit the disease through scratches, bites and direct contact with injured skin. In mammals, the clinical picture is chronic or acute with the appearance of skin lesions. The disease is considered a public health problem, as it affects the population of endemic areas. The present work was designed to analyze the manifestation of the disease in domestic cats, reviewing clinical signs, diagnosis, prevention, treatment and also makes an alert for its importance in public health. Educational measures are needed to make the population aware of the effects of waste on One Health.(AU)

Effects of microencapsulated carvacrol and cinnamaldehyde on feed digestibility, intestinal mucosa, and biochemical and antioxidant parameters in broilers

The objective of this study was to evaluate the effects of different levels of microencapsulated carvacrol and cinnamaldehyde on metabolizable energy, feed digestibility, intestinal morphometric analysis, and antioxidant parameters in broilers. A completely randomized design with five treatments and eight replications of eight broilers (Cobb male) was used, and collections were carried out at 20 and 42 days of age. Carvacrol and cinnamaldehyde concentrations (mg/kg) were: 0 (control), 50, 100, 150, and 200. Carvacrol and cinnamaldehyde improved apparent metabolizable energy but did not change protein and ether extract digestibility. Supplementation increased intestinal villus height and villi:crypt ratio; in which 100 mg/kg produced the greatest villus height. Serum uric acid levels were lower in birds receiving supplementation. Improvement in the activity of glutathione peroxidase and glutathione-S-transferase was observed, while lower uric acid, thiobarbituric acid reactive substances, and reactive oxygen species levels were observed. Microencapsulated carvacrol and cinnamaldehyde improve apparent metabolizable energy and can be administered in broiler feed without risk to the bird's health. These supplements may serve as alternative products to aid the performance of commercial poultry.

Quality of breast reconstruction service at a university hospital as assessed by the patients

Purpose: To evaluate the quality of breast reconstruction service at a university hospital, as assessed by the patients. Methods: This cross-sectional study enrolled adult women who underwent immediate or delayed breast reconstruction by any technique performed at a university hospital between 1 and 24 months before the assessment. The Brazilian version of the Health Service Quality Scale (HSQS) was self-applied to the participants. The HSQS produces percentage scores, which are expressed in values ranging from 0 to 10 for each domain of the scale, and into an overall percentage quality score. The management team was asked to establish a minimum satisfactory score for the breast reconstruction service. Results: Ninety patients were included. The management team considered 8.00 the minimum satisfactory score for the service. The overall percentage score was 93.3%. Only one domain, 'Support,' had an average score lower than that considered satisfactory (7.22 ± 3.0); while the others had higher scores. The domain that scored highest was 'Qualification' (9.94 ± 0.3), followed by 'Result' (9.86 ± 0.4). There was a positive correlation between 'type of oncologic surgery' and 'intentions of loyalty to the service' (ρ = 0.272; p = 0.009) and a negative correlation between 'education' and 'quality of the environment' (ρ = ­0.218; p = 0.039). The higher the patient's level of education, the higher the score attributed to 'relationship' (ρ = 0.261; p = 0.013) and the lower the score of 'aesthetics and functionality' (ρ = ­0.237; p = 0.024). Conclusion: The quality of the breast reconstruction service was considered satisfactory, but there is a demand for structural improvements, better interpersonal relationships, and a stronger support network for patients.

In-house serological ELISA as a leishmaniosis diagnostic test: development and applications in canines from the western border of Brazil / ELISA "in house" para o diagnóstico de leishmaniose: desenvolvimento e aplicação em caninos da fronteira Oeste do Brasil

ABSTRACT: Leishmaniosis is a great public health problem affecting both humans and animals. The disease is caused by the protozoan Leishmania spp., which has a complex cycle involving a phlebotomine vector. The ELISA test (Enzyme-Linked Immunosorbent Assay) along with a chromatographic immunoassay was defined by the Brazil Health Ministry as the confirmatory screening protocol in 2011. Uruguaiana city is 630 km away from Porto Alegre, which makes it difficult to send samples and diagnose leishmaniasis, as well as receive quick results. In view of this, the present study evaluated an in-house indirect ELISA method compared to indirect immunofluorescence assay (IFA) and dual-path platform chromatographic immunoassay (DPP-BioManguinhos®) for the detection of an immune response to Leishmania spp. in canine species. The serological evaluation included 48 canines from the western border of Brazil (Uruguaiana and Barra do Quaraí city). Among the 48 canine samples tested, 18 were positive when using the ELISA technique, 19 were positive with IFA, and 17 were positive with rapid test DPP®. The ELISA technique showed a sensitivity/specificity of 83.3%/86.7% when compared to IFA and 100%/96.8% compared to DPP®. The present study showed a prevalence of 37.5%, demonstrating that the infection circulates in the studied population. It can be concluded that the ELISA technique was valuable for use in field conditions when performing screening tests in endemic areas.

RESUMO: A leishmaniose é um grande problema de saúde pública que afeta tanto humanos quanto animais. A doença é causada pelo protozoário Leishmania spp., que possui um ciclo complexo envolvendo um vetor flebotomíneo. O teste ELISA (Enzyme-Linked Immunosorbent Assay), juntamente com um imunoensaio cromatográfico, foi definido pelo Ministério da Saúde do Brasil como protocolo de triagem confirmatória em 2011. A cidade de Uruguaiana fica a 630 km de Porto Alegre, o que dificulta o envio de amostras e o diagnóstico da leishmaniose, além da demora para obter os resultados. Diante disso, o presente estudo teve como objetivo avaliar um método de ELISA indireto in-house comparado ao ensaio de imunofluorescência indireta (IFA) e imunoensaio cromatográfico de plataforma de dupla via (DPP-BioManguinhos®) para a detecção de uma resposta imune contra Leishmania spp. na espécie canina. A avaliação sorológica incluiu 48 caninos da fronteira oeste do Brasil (cidade de Uruguaiana e Barra do Quaraí). Das 48 amostras caninas testadas, 18 foram positivas na técnica de ELISA, 19 foram positivas com IFA e 17 foram positivas com o teste rápido DPP®. A técnica de ELISA apresentou sensibilidade/especificidade de 83,3%/86,7% quando comparada ao IFA e 100%/96,8% em relação ao DPP®. O presente estudo apresentou prevalência de 37,5%, demonstrando que a infecção circula na população estudada. Pode-se concluir que a técnica de ELISA foi valiosa para uso em condições de campo na realização de testes de triagem em áreas endêmicas.

A blend of thyme and rosemary powders with poultry by-product meal can be used as a natural antioxidant in broilers

A total of 500, 14-d old male Ross 308 broilers were allocated into five treatments (4 replicates each) including: a negative (NC) and positive control diet (PC) which supplemented without and with 7% poultry by-product meal (PBPM), respectively and three levels of additive supplementation of thyme and rosemary powders in the basal diets: 0.750% rosemary powder (PCR); 0.375% thyme powder + 0.375% rosemary powder (PCRT), and 0.750% thyme powder (PCT) rosemary powder. The PCRT diet improved (p<0.05) average daily gain and feed conversion ratio by 5.62 and 10.37% compared to PC, respectively. The serum concentration of lipids (triglycerides, cholesterol, high-density lipoprotein, and low-density lipoprotein) was decreased while the ilealvillus heightand ratio of villus height to crypt depth as well as ileal microbiota population were improved(p<0.05) in response to inclusion PCRT diet compared to PC diet. The blood serum concentration of malondialdehyde was statistically decreased (p<0.05) by supplementation of PCRT in broiler diets. Our results suggested that supplementation of a blend of thyme and rosemary powders at the level of 0.375% of each into broiler diet during d 14-42 has merit to be used as a natural antioxidant in diets formulated by PBPM.(AU)

Aeromonassp. in freshwater fish and antimicrobial resistance: emerging pathogen / Quantificação deAeromonassp. em peixes de água doce e resistência a antimicrobianos: patógeno emergente

ABSTRACT: The bacteria Aeromonassp. are naturally reported in aquatic ecosystems and possess pathogenic potential, being considered as emerging pathogens in humans and animals. They also cause considerable losses in fish farming and, through water, can contaminate numerous foods. This study quantified and analyzed the antimicrobial resistance profile of Aeromonassp. in fish. A total of 72 samples of two fish varieties (leather fish, Pseudoplatystomafasciatumx Leiariusmarmoratusand round fish, Colossomamacropomumx Piaractusmesopotamicusand Colossomamacropomumx Piaractusbrachypomus) were purchased from two types of sources (fresh and frozen) and three commercial establishments (supermarket, market, and fishmonger). The 55 isolated Aeromonascultures were evaluated for their antimicrobial resistance profile by the disc diffusion method. Upon quantification, the count of Aeromonassp. ranged from 4.22 to 6.00 Log CFU/g; ten different species, including A. eucrenophila, A. hydrophila, A. caviae, A. media, A. jandaei, A. veroniibv. sobria, A. trota, A. schubertii, A. veroniibv. veronii, and A. shigelloides, were identified. Among the 55 isolates, 64.45% showed resistance to Ampicillin-sulbactam, and 75% were sensitive to gentamicin and ciprofloxacin. It was concluded that 100% of the evaluated samples were contaminated by Aeromonassp., which may present a risk to consumer health since bacteria can be etiological agents of Foodborne Diseases. The antimicrobial resistance profile showed resistance to ampicillin and multi-resistance to different classes of antimicrobials, demonstrating problems with choosing an antimicrobial for treatment of any disease.

RESUMO: Aeromonas sp. são bactérias presentes naturalmente no ecossistema aquático e apresentam potencial patogênico, sendo considerados patógenos emergentes em humanos e animais. Ainda, causam perdas consideráveis em piscicultura e, através da água, podem também contaminar inúmeros alimentos. Diante disso o objetivo do trabalho foi quantificar e analisar o perfil de resistência aos antimicrobianos de bactérias do gênero Aeromonas sp. em peixes. Um total de 72 amostras foram adquiridas, sendo duas variedades de peixes (peixe de couro Pseudoplatystoma fasciatum x Leiarius marmoratus e os peixes redondos Colossoma macropomum x Piaractus mesopotamicus e Colossoma macropomum x Piaractus brachypomus), dois tipos (fresco e congelado) e de três estabelecimentos comerciais (supermercado, feira e peixaria). As 55 culturas isoladas de Aeromonas foram avaliadas quanto ao perfil de resistência aos antimicrobianos pelo método de difusão em disco. Os valores encontrados na quantificação de Aeromonas sp. variaram de 4,22 a 6,00 Log UFC/g, e foram identificadas dez espécies diferentes, sendo A. eucrenophila, A. hydrophila, A. caviae, A. media, A. jandaei, A. veronii bv. sobria, A. trota, A. schubertii, A. veronii bv. veronii e A. shigelloides. Entre os 55 isolados, 64,45% apresentaram resistência a Ampicilina-sulbactam, 75% foram sensíveis à gentamicina e ciprofloxacina. Concluiu-se que 100% das amostras avaliadas estavam contaminadas por Aeromonas sp. podendo apresentar risco à saúde do consumidor visto que estas podem ser agentes etiológicos de Doenças Transmitidas por Alimentos (DTAs). O perfil de resistência aos antimicrobianos comprovou a resistência a ampicilina e apresentou multirresistência a diferentes classes de antimicrobianos, demonstrando um problema relacionado à opção de antimicrobiano para tratamento no caso do desenvolvimento de alguma doença.

The impact of laparoscopic gynecological surgery training on the technicity index of a developing country center

Purpose: To compare laparoscopic gynecological surgery training between a developed country's reference center (host center) and a public reference service in a developing country (home center), and use the technicity index (TI) to compare outcomes and to determine the impact of laparoscopic gynecological surgery fellowship training on the home center's TI. Methods: The impact of training on the home center was assessed by comparing surgical performance before and after training. TI was assessed in 2017 in the host center, and before and after training in the home center. Epidemiological and clinical data, and information on reason for surgery, preoperative images, estimated intraoperative bleeding, operative time, surgical specimen weight, hospital stay length, complication and reintervention rates were collected from both institutions. Home center pre-training data were retrospectively collected between 2010 and 2013, while post-training data were prospectively collected between 2015 and 2017. A two-tail Z-score was used for TI comparison. Results: The analysis included 366 hysterectomies performed at the host center in 2017, and 663 hysterectomies performed at the home center between 2015 and 2017. TI in the host center was 82.5%, while in the home center it was 6% before training and 22% after training. There were no statistical differences in length of hospital stay, preoperative uterine volume, surgical specimen weight and complication rate between centers. However, significantly shorter mean operative time and lower blood loss during surgery were observed in the host center. Conclusions: High-quality laparoscopic training in a world-renowned specialized center allowed standardizing laparoscopic hysterectomy procedures and helped to significantly improve TI in the recipient's center with comparable surgical outcomes.

This study aimed to search parasites in 333 ornamental fish from five Brazilian states (Ceará, Minas Gerais, São Paulo, Paraná and Santa Catarina). Fish were sent from eight farms located in the municipalities of Fortaleza, Patrocínio do Muriaé, São Francisco do Glória, Cascavel, Timbó, Iguape, Jacareí and Mairinque. All fish received anesthesia earlier to euthanasia procedures. After the search for parasites, it was verified that 70.6% (235/333) of fishes were infected by at least one type of parasite, being 12 types of parasites identified: monogeneans, digenean metacercariae, cestodes, nematodes, Lernaea cyprinacea, trichodinids, Piscinoodinium pillulare, Ichthyophthirius multifiliis, diplomonad flagellates, Ichthyobodo sp., Chilodonella sp., and Tetrahymena sp. The proportion of infected fishes among the farms is compared through statistical tests, besides, animal handling adopted in each farm is also discussed. The importance of ensuring fish health in order to make the ornamental freshwater fish industry economically viable and reduce losses in production is highlighted.

O objetivo deste estudo foi pesquisar parasitas presentes em 333 peixes ornamentais de cinco estados brasileiros (Ceará, Minas Gerais, São Paulo, Paraná e Santa Catarina). Os peixes eram oriundos de oito pisciculturas localizadas nos municípios de Fortaleza, Patrocínio do Muriaé, São Francisco do Glória, Cascavel, Timbó, Iguape, Jacareí e Mairinque. Todos os peixes foram anestesiados e eutanasiados para a pesquisa de parasitas. Após análise microscópica, foi verificado que 70.6% (235/333) dos peixes estavam infectados por ao menos uma espécie de parasita, sendo identificados 12 tipos: monogenoides, metacercárias, cestoides, nematoides, Lernaea cyprinacea, tricodinídeos, Piscinoodinium pillulare, Ichthyophthirius multifiliis, flagelados diplomonados, Ichthyobodo sp., Chilodonella sp., e Tetrahymena sp. A proporção de peixes infectados entre cada piscicultura é comparada através de testes estatísticos, além disso, o manejo adotado pelas diferentes pisciculturas também é discutido. A importância de assegurar a sanidade de peixes ornamentais, de forma a tornar a atividade economicamente viável e reduzir perdas na produção é enfatizada.

COVID-19 impacts on healthcare access in sub-Saharan Africa: an overview

Abstract This overview aimed to describe the situation of healthcare access in sub-Saharan Africa, excluding South Africa, during the COVID-19 pandemic. A PubMed® search from March 31, 2020, to August 15, 2022, selected 116 articles. Healthcare access and consequences of COVID-19 were assessed based on comparisons with months before its onset or an identical season in previous years. A general reduction of healthcare delivery, associated with the decline of care quality, and closure of many specialty services were reported. The impact was heterogeneous in space and time, with an increase in urban areas at the beginning of the pandemic (March-June 2020). The return to normalcy was gradual from the 3rd quarter of 2020 until the end of 2021. The impact of COVID-19 on the health system and its use was attributed to (a) conjunctural factors resulting from government actions to mitigate the spread of the epidemic (containment, transportation restrictions, closures of businesses, and places of entertainment or worship); (b) structural factors related to the disruption of public and private facilities and institutions, in particular, the health system; and (c) individual factors linked to the increase in costs, impoverishment of the population, and fear of contamination or stigmatization, which discouraged patients from going to health centers. They have caused considerable socio-economic damage. Several studies emphasized some adaptability of the healthcare offer and resilience of the healthcare system, despite its unpreparedness, which explained a return to normal activities as early as 2022 while the COVID-19 epidemic persisted. There appears to be a strong disproportion between the moderate incidence and severity of COVID-19 in sub-Saharan Africa, and the dramatic impact on healthcare access. Several articles make recommendations for lowering the socioeconomic consequences of future epidemics to ensure better management of health issues.

Analysis of the Quality of Eggs Marketed in Santarém, Brazil

Eggs are foods with almost perfect proteins, while also containing nutrients with high biological value. The purpose of this study was to evaluate the morphological structure, physical-chemical, nutritional, and microbiological parameters of commercial and free-range eggs sold in the municipality of Santarém, State of Pará, Brazil. The two types of eggs were also compared to check for any differences in quality. The evaluations were conducted on variables such as Haugh unit, weight loss, egg width and length, specific gravity, yolk and albumen dimensions, pH, among others. A total of 240 eggs were purchased in the Brazilian municipality of Santarém (2º45'06" S and 54º70'09" W). A statistical study was also performed using the BIOESTAT 5.0 statistical program. A comparison of the industrial and free-range eggs and their various parameters is given in the tables along with the coefficient of variation. The results obtained were satisfactory and showed that the quality of eggs is affected more by environmental factors than by the source from which they are obtained. The results were also compared to previously published literature, and it was determined that this study offers a better foundation for the nutritional examination of egg quality.(AU)

Seroepidemiology of leptospirosis in horses from Santarém, Pará / Soroepidemiologia de leptospirose em equinos da região de Santarém, Pará

Leptospirosis is an endemic zoonotic disease that is distributed worldwide, which has the potential to have health and economic impacts. Leptospira spp. is spiral-shaped and capable of infecting mammals, including horses, which may result in asymptomatic or clinical forms. Therefore, the current study aimed to analyze the frequency of anti-Leptospira antibodies in serum samples from horses from Santarém, Pará, Brazil. For that purpose, 88 blood samples from horses without a history of leptospirosis vaccination were serologically evaluated through the microscopic agglutination technique (MAT) with a 13 serovars, belonging to ten different serogroups. There were 58 samples that were seropositive (65.90%), which included 28 samples seropositive for Pyrogenes (48.3%), 24 for Autumnalis (41.4%), 18 for Icterohaemorrhagiae (31.0%), and 16 for Grippotyphosa (27.6%). Even without clinical suspicion of leptospirosis or a history of vaccination, the horses showed different frequency of seropositivity. Considering the well-known impact of leptospirosis in human and animal health, our results are important to establish preventive measures to reduce the economic loss in equine production as well as a reduction in public health risk.

Leptospira spp. é a bactéria causadora da leptospirose, uma doença endêmica, distribuída mundialmente, de caráter zoonótico responsável por gerar impacto sanitário e também econômico. Esse microrganismo, com característica espiralada, infecta mamíferos, dentre eles, os equinos. Estes animais, podem apresentar a doença na forma assintomáticos ou clínica. Desta forma, o atual estudo objetivou analisar amostras equinas na região de Santarém- Pará. Analisou-se 88 amostras de animais que não apresentavam histórico de vacinação contra a leptospirose, através da técnica da Microaglutinação Microscópica (MAT), utilizando um painel de13 sorovares, pertencentes a dez diferentes sorogrupos. Desses animais, 58 foram soropositivos (65,90%), distribuídos em 28 (48,3%) amostras soro reagentes para Pyrogenes, 24 (41,4%) para Autumnalis, 18 (31%) para Icterohaemorrhagiae e 16 (27,6%) para Grippotyphosa. Mesmo não havendo suspeita de leptospirose, os animais apresentaram diferentes frequências sorológicas. Considerando-se o conhecido impacto da leptospirose na saúde humana e animal, nossos resultados apontam que é de suma importância estabelecer medidas de prevenção para reduzir perdas econômicas e não oferecer riscos à saúde pública.

Post-release challenges: case report of parasitosis by Ancylostoma sp. in a giant anteater (Myrmecophaga tridactyla) / Desafios pós-soltura: relato de caso de parasitose por Ancylostoma sp. em tamanduá-bandeira (Myrmecophaga tridactyla)

The giant anteater (Myrmecophaga tridactyla) is classified as vulnerable to extinction. Here, we report the occurrence of ancylostomiasis in a young male Myrmecophaga tridactyla. The animal was raised from a puppy in captivity with management directed toward rehabilitation and monitored soft release. Five months after release, significant weight loss was noted in the individual, who was captured for examinations, with detection of Ancylostoma sp. in coproparasitological analysis. Although common in domestic carnivores, this is the first report of hookworm disease in free-ranging giant anteaters. Due to the stress factor arising from adapting to the challenges in the new environment, long-term post-release monitoring of animals undergoing rehabilitation is extremely important to increase the chance of survival of individuals. The giant anteater was released after treatment with vermifuge composed of fenbendazole, pyrantel pamoate, and praziquantel.

O tamanduá-bandeira (Myrmecophaga tridactyla) está classificado como vulnerável quanto ao risco de extinção. O objetivo deste trabalho é reportar a ocorrência de ancilostomíase em um macho jovem da espécie. Trata-se de um indivíduo que foi criado desde filhote em cativeiro, com manejo direcionado para a reabilitação e a soltura branda. Durante o monitoramento, cinco meses após a soltura, observou-se que o animal havia perdido peso, por isso ele foi capturado para avaliação médica veterinária, e constatou-se parasitismo por Ancylostoma sp. no exame coproparasitológico. Apesar de apresentar ocorrência comum em carnívoros domésticos, este é o primeiro relato de ancilostomíase em tamanduá-bandeira em vida livre. Devido ao estresse de adaptação, juntamente com os desafios do novo ambiente, a monitoração pós-soltura a longo prazo é de extrema importância para aumentar a chance de sobrevivência dos animais. O indivíduo foi solto após tratamento com vermifugação com a associação de fembendazol, pamoato de pirantel e praziquantel.

Resistance profile of bacterial isolates from different llama microbiotas (Lama glama Linnaeus 1758) / Perfil de resistência de isolados bacterianos de diferentes microbiotas de lhamas (Lama glama Linnaeus 1758)

Este trabalho objetivou o isolamento e a identificação das bactérias de diferentes microbiotas de lhamas. Para tanto, testes de disco difusão e diagnósticos moleculares para pesquisa de genes de resistência foram realizados. Foram isolados cinco Staphylococcus spp. coagulase positiva e 19 Staphylococcus spp. coagulase negativa, 19 Escherichia coli¸ duas Pantoea agglomerans, uma Koserella trabulsii, uma Enterobacter aerogenes e uma Klebsiella Pneumoniae. Entre os isolados de Staphylococcus spp., 79,17% foram resistentes ao sulfazotrim, 45,83% resistentes à penicilina e 20,83% à ampicilina. Foi confirmada a presença do gene mecA em apenas um isolado oxacilina resistente. No teste de disco difusão, 58,3% das enterobactérias foram resistentes à amoxicilina + ácido clavulânico e à cefotaxima, 50% à ceftazidima e ceftriaxona, e 33,3% à amoxicilina. Ainda entre os isolados Gram-negativos, não houve a expressão fenotípica de isolados ESBL. O presente trabalho expôs a presença de microrganismos resistentes a antibióticos em lhamas que não tiveram contato prévio com essas drogas, além da presença do gene mecA em um dos animais. O conhecimento da microbiota bacteriana de diferentes espécies animais tem se tornado cada vez mais importante. Tal relevância se deve à possibilidade de esses microrganismos serem compartilhados entre os animais, os humanos e até mesmo o meio ambiente.

Molecular identification of pathogenic Escherichia coli virulence genes and histopathological analysis in chickens condemned for airsacculitis / Identificação molecular de genes de virulência de Escherichia coli e análise histopatológica em frangos condenados por aerossaculite

ABSTRACT: The present study identified virulence genes and pathological changes caused by Escherichia coli in chicken carcasses condemned for airsacculitis and assessed if the histopathological examination and polymerase chain reaction (PCR) were effective for studies like this. Trachea, liver, and lung were collected from 30 chickens with suspected airsacculitis that has been condemned in the inspection line. The samples were analyzed by PCR to simultaneously identify two virulence genes (iss and tsh genes) and for histopathological testing. PCR efficiently genotypically characterize the E. coli isolates, where the virulence genes iss and tsh were found in three birds simultaneously. The histopathological examination detected a predominance of heterophils and mononuclear cells in the trachea (100%), lung (90%), and liver (13.3%). The liver was the organ where practically no alteration was diagnosed. The results of multiplex PCR for the tsh and iss virulence genes indicate the great potential of the approach in the characterization of E. coli isolates. Unspecific identification did not occur, thus making it necessary to use technologies for the identification and prevention of this agent in aviaries and poultry abattoirs.

RESUMO: O objetivo do presente estudo foi identificar genes de virulência e alterações patológicas provocadas por Escherichia coli em carcaças de frango condenadas por aerossaculite e se o exame histopatológico e uma Reação em Cadeia da Polimerase (PCR) são eficazes para os estudos dessa natureza. Para isso, foram coletados traqueia, fígado e pulmão de 30 frangos condenados na linha de inspeção, com suspeita de aerossaculite. As amostras foram submetidas a PCR para a identificação de dois genes de virulência de modo simultâneo (genes iss e tsh) e ao teste histopatológico. A PCR foi eficiente para caracterizar genotipicamente os isolados de E. coli, em que se constatou em três aves os genes de virulência iss e tsh simultaneamente. No exame histopatológico detectou-se a predominância de heterófilos e mononucleares na traqueia 100%, no pulmão 90% e no fígado 13,3%. O fígado foi o órgão onde praticamente não foi diagnosticada nenhuma alteração. Diante dos resultados obtidos, foi possível observar que a PCR multiplex para os genes de virulência tsh e iss apresenta um grande potencial na caracterização de isolados de E. coli, já que não gerou identificação inespecífica, com isso faz-se necessária a utilização de tecnologias para identificação e prevenção desse agente nos aviários e matadouros avícolas.

Pantoea ananatis in Oryza sativa in Brazil / Pantoea ananatis em Oryza sativa no Brasil

ABSTRACT: The state of Santa Catarina is the second-largest producer of rice seeds in Brazil. Research on phytopathogenicbacterias in this crop is scarce and the high frequency of panicle diseases leads to the hypothesis that seeds may be infected by bacteria. This research quantified the incidence of bacteria in the seeds, verified the bacteria viability during the storage period and characterized the associated bacteria. Seeds from the 2018/19 and 2019/20 seasons were analyzed. To check the incidence, the seeds were disinfected, plated on a nutrient agar + fungicide culture medium, and incubated for seven days at 27 °C. To assess viability, every 45 days, three cultivars stored in a processing unit were subjected to the same detection methodology. To characterize, prevalent colonies were isolated on semi-selective culture medium Pantoea genus-specific agar (PGSA), where the ones that showed growth were subjected to deoxyribonucleic acid (DNA) extraction and Polymerase Chain Reaction (PCR), DNA sequencing, and sequence comparison on GenBank. The hypersensitivity reaction (HR) in tobacco was performed using a bacterial suspension of each isolate. All seed samples had an average incidence of 83%. During storage, the seeds maintained stable bacterial viability, with an average incidence of 95% at the beginning of storage and 99% at the end of it. All isolates that grew in PGSA culture medium were identified by molecular characterization with 100% identity with two specimens of Pantoeaananatis and one of them induced RH in tobacco.

RESUMO: O estado de Santa Catarina é o segundo maior produtor de sementes de arroz do Brasil. As pesquisas com bactérias fitopatogênicas nesta cultura são escassas e a alta frequência de doenças da panícula leva à hipótese de que sementes podem estar infectadas por bactérias. O objetivo desta pesquisa foi quantificar a incidência de bactérias nas sementes, verificar a viabilidade das bactérias durante o período de armazenamento e caracterizar as bactérias associadas. Foram analisadas sementes das safras 2018/19 e 2019/20. Para verificar a incidência, as sementes foram desinfestadas, plaqueadas em meio de cultura ágar nutriente + fungicida e incubadas por sete dias a 27 °C. Para avaliar a viabilidade, a cada 45 dias, três cultivares armazenadas em uma unidade de beneficiamento foram submetidas à mesma metodologia de detecção. Para caracterizar, colônias prevalentes foram isoladas em meio de cultura semisseletivo Pantoea genus-specific ágar (PGSA), onde as que apresentaram crescimento foram submetidas à extração do ácido desoxirribonucléico (DNA) e Reação em Cadeia da Polimerase (PCR), sequenciamento do DNA e comparação de sequências no GenBank. A reação de hipersensibilidade (HR) em tabaco foi realizada utilizando uma suspensão bacteriana de cada isolado. Todas as amostras de sementes apresentaram incidência média de 83%. Durante o armazenamento, as sementes mantiveram viabilidade bacteriana estável, com incidência média de 95% no início do armazenamento e 99% ao fim. Todos os isolados que cresceram no meio de cultura PGSA, foram identificados por caracterização molecular com 100% de identidade com dois espécimes de Pantoea ananatis e um deles induziu HR em tabaco.

Veterinarian's perceptions of animal euthanasia and the relation to their own mental health / Percepções do médico veterinário a respeito da eutanásia animal e a relação com sua saúde mental

ABSTRACT: Ethical and moral issues surround the practice of animal euthanasia, which often damages the veterinarian's mental health, leading to psychological problems and even suicide. This study aimed to evaluate veterinarians' perceptions about euthanasia and the possible implications of the practice for their mental health and seek to identify gaps in the training of these professionals. Data collection occurred by applying an online questionnaire sent to veterinarians working in the Brazilian territory. Among the 243 participants, 78% said they did not have classes that broadly addressed the practice of animal euthanasia and dysthanasia during undergraduate disciplines; in addition, 71% claimed that they did not address subjects such as medical ethics, psychology, mental health, and verbal communication. The vast majority (90%) considered not trained to deal with patient death, and 67% have already questioned whether the procedure was the best alternative. The presence of sadness after performing euthanasia was frequent among participants. Small animal clinicians were more susceptible to the presence of this feeling when compared to a veterinarian from other areas. Most veterinarians (86%) believed that the practice of animal euthanasia poses risks to the performer's mental health, and 89% claimed that it influences their mental health. 17% of the participants were using controlled medications during the research period. So, given these findings, it is evident that animal euthanasia negatively affects the mental health of those who perform it. Measures are needed to minimize the impacts arising from the practice, aiming to improve this population's health and well-being.

RESUMO: A prática da eutanásia animal é circundada por questões éticas e morais, o que resulta, muitas vezes, em prejuízo à saúde mental do veterinário, podendo levar ao desenvolvimento de problemas psíquicos e mesmo ao suicídio. O presente trabalho teve como objetivo avaliar as percepções do médico veterinário a respeito da eutanásia e as possíveis implicações da prática à sua saúde mental, além de buscar identificar lacunas acerca do tema na formação destes profissionais. A coleta dos dados ocorreu mediante aplicação de questionário online encaminhado a médicos veterinários atuantes no território brasileiro. Dentre os 243 participantes, 78% afirmaram não ter tido durante a graduação disciplinas que abordassem de forma ampla a prática da eutanásia e distanásia animal; além disso, 71% alegaram que conteúdos como ética médica, psicologia, saúde mental e comunicação verbal não foram tratados. A grande maioria (90%) considera não ter sido preparado para lidar com a morte de seus pacientes e 67% já questionaram se o procedimento era o melhor a se fazer naquele momento. Á presença de tristeza após realização de uma eutanásia apresentou-se de forma frequente entre os participantes. Os clínicos de pequenos animais mostraram-se mais suscetível à presença deste sentimento quando comparados aos veterinários de outras áreas. A maior parte dos médicos veterinários (86%) acredita que a prática da eutanásia animal pode oferecer riscos a saúde mental do realizador e 89% afirmam que a mesma pode ter influencia sobre sua saúde mental. Sendo que, 17% dos participantes estavam fazendo uso de medicamentos controlados durante o período da pesquisa. Diante desses achados, evidencia-se que a prática da eutanásia animal repercute negativamente na saúde mental de quem a executa, sendo necessárias medidas que minimizem os impactos advindos da prática, visando melhoria na saúde e bem-estar desta população.
