Biodiversity of commercially important finfish species caught by mid-water and bottom trawls from two different coasts of Arabian Sea: Threats and conservation strategies / Biodiversidade de espécies de peixes comercialmente importantes capturadas por redes de arrasto de médio e fundo do Baluchistão e costas de Sindh do mar da Arábia no Paquistão: Ameaças e estratégias de conservação

Abstract This study was conducted to estimate the diversity and the occurrence of commercially important finfish species collected by twenty fish sampling site of Sindh and Baluchistan coasts of the Arabian Sea in Pakistan from January to December 2019. Additionally, physicochemical characteristics of seawater were analyzed from these selected sites and found to be within suitable ranges required for fish growth and survive. A total of 81287 fish individuals were collected and identified as 49 species belonging to 26 families in our study. The most diversified family was Sparidae (13 species) followed by Carangidae and Lutjanidae (4 species), Mullidae, Serranidae, Ariidae (3 species), and Sciaenidae (2 species). The remaining 20 families were represented by only one species. The values of Shannon diversity index calculated for the four selected habitats revealed that high fish diversity was reported at Sonmiani Coast (H'=1.81), while less at Ormara Coast (H'=0.23). Likewise, Evenness index (E) was high at Sonmiani Coast (E=0.50) and less fish diversity was reported at Ormara Coast (E=0.06). Reducing risks to threatened marine species in coastal habitats also requires conservation actions at multiple scales. Thus, it was concluded that our study could be valuable in providing the more information's regarding to the diversity of finfish species and their occurrence along the Pakistan Coast. Further, to better understand the effects, regular monitoring and conservation measures should be taken to mitigate the influence of anthropogenic activities and protect finfish diversity from further decline

Resumo Este estudo foi conduzido para estimar a diversidade e a ocorrência de espécies de peixes comercialmente importantes coletadas por vinte locais de amostragem de peixes nas costas de Sindh e Baluchistão do mar da Arábia, no Paquistão, de janeiro a dezembro de 2019. Além disso, as características físico-químicas da água do mar foram analisadas a partir desses peixes locais selecionados e considerados dentro dos intervalos adequados necessários para o crescimento e sobrevivência dos peixes. Um total de 8.1287 indivíduos de peixes foi coletado e identificado como 49 espécies pertencentes a 26 famílias em nosso estudo. A família mais diversificada foi Sparidae (13 espécies), seguida por Carangidae e Lutjanidae (4 espécies), Mullidae, Serranidae, Ariidae (3 espécies) e Sciaenidae (2 espécies). As 20 famílias restantes foram representadas por apenas uma espécie. Os valores do índice de diversidade de Shannon calculados para os quatro habitats selecionados revelaram que uma alta diversidade de peixes foi relatada na costa Sonmiani (H' = 1,81), enquanto menos na costa Ormara (H' = 0,23). Da mesma forma, o índice de regularidade (E) foi alto na costa de Sonmiani (E = 0,50) e menos diversidade de peixes foi relatada na costa de Ormara (E = 0,06). A redução dos riscos para as espécies marinhas ameaçadas em habitats costeiros também requer ações de conservação em várias escalas. Assim, concluiu-se que nosso estudo pode ser valioso para fornecer mais informações sobre a diversidade de espécies de peixes finos e sua ocorrência ao longo da costa do Paquistão. Além disso, para compreender melhor os efeitos, medidas regulares de monitoramento e conservação devem ser tomadas para mitigar a influência das atividades antropogênicas e proteger a diversidade de peixes finos de um declínio maior.

Epidemiological aspects of scorpionic accidents in a municipality in Brazils northeastern

Abstract Scorpionic accidents are a major public health problem due to the high occurrence with potential seriousness. In this manner, the research aimed to analyze the occurrence of scorpionic accidents in a municipality in the northeastern of Brazil. An exploratory, descriptive study was made, with a quantitative approach, using secondary data which was gotten from the Notifiable Diseases Information System (SINAN), from 2008 to 2018. Data such as neighborhood, presence of street markets were also used, and the existence of sanitation and climatic data such as temperature and season. Geoprocessing was used to identify possible changes in the environment. In the analyzed period, 9,330 cases of scorpion accidents were recorded, with an average of 848 annual notifications. Scorpionic accidents occurred more frequently in women (5,686; 60.94%). Individuals aged 20 to 29 years (1.727; 18.51%) were more frequent to scorpion stings. Regarding the body parts where the stings were made, the highlights were on the foot (3.515; 37.67%) followed by the hand (2.818; 30.20%). No statistically significant relation was observed between climatic factors and scorpionic accidents. However, the high number of cases of scorpionic accidents was observed in the last 11 years studied. It was evident that during the study period there was no statistical relationship when climatic factors were correlated to scorpionic accidents. On its turn, when it was verified the results of the geoprocessing analysis, it was seen that anthropic factors have been motivating the potentiation of the occurrence of these accidents.

Por sua vez, ao verificar os resultados da análise de geoprocessamento foi visto que fatores antrópicos têm sido motivadores da potencialização da ocorrência desses acidentes.

Compressive lesions in the central nervous system of cattle: a retrospective study of 50 cases in the Amazon biome / Lesões compressivas no sistema nervoso central de bovinos: um estudo retrospectivo de 50 casos no bioma amazônico

The present study gathered epidemiological and clinical-pathological information about cattle with compressive lesions in the central nervous system (CNS). The retrospective study included observations made in 50 cattle from 1998 to 2021 by reviewing the clinical records of animals with compressive lesions in the CNS treated at the Veterinary Hospital of the Veterinary Medicine Institute of the Federal University of Pará. The animals had clinical signs and were subjected to general and specific clinical examination of the nervous system. Blood samples were collected from 13 animals for complete blood counts, and cerebrospinal fluid (CSF) samples were collected from four animals for physical evaluation. Twenty-nine cattle underwent necropsy. The most affected sites were the T3-L3 (46%, 23/50), C1-C5 (22%, 11/50), C6-T2 (14%, 7/50), sacrococcygeal vertebrae, (4%, 2/50), L4-S2 (2%, 1/50), brain (8%, 4/50) and cerebellum (4%, 2/50). The age of the affected cattle ranged from 20 days to 16 years, with a higher occurrence in animals younger than 12 months (56%, 28/50). More Females were affected (58%, 29/50) than males (42%, 21/50). The clinical signs varied according to the location of the lesion and were mainly represented by ataxia, paresis or paralysis of the limbs, inability to stand and walk, postural changes, hyperesthesia in the extremities, and loss of skin sensitivity at the location of the lesion. The necropsy findings revealed changes such as abscesses in the vertebral body; intervertebral space in the medullary canal, pituitary and cerebellum; granuloma in the arch of the vertebra; fractures of the body of the vertebrae; subarachnoid haematoma; congenital bone alteration causing spinal cord compression; and spondylitis. Detailed anamnesis and clinical examination of the CNS, associated with necropsy findings, were important to determine the cause of the disease, correlate with the clinical picture and locate the affected segments of the CNS in the cattle. It is important to include these diseases in the list of differential diagnoses in cattle with nervous symptoms.

O presente trabalho reúne informações epidemiológicas e clínicopatológicas de bovinos com lesões compressivas no sistema nervoso central (SNC). O estudo retrospectivo compreendeu as observações realizadas em 50 bovinos durante os anos de 1998 a 2021, por meio da revisão dos arquivos de fichas clínicas de animais com lesões compressivas no SNC atendidos pelo Hospital Veterinário do Instituto de Medicina Veterinária da Universidade Federal do Pará. Os animais atendidos com sinais clínicos foram submetidos a exame clínico geral e específico do sistema nervoso. Foram coletadas amostras de sangue de 13 animais para realização de hemograma e amostras de líquido cefalorraquidiano de quatro animais para avaliação física. Foram submetidos à necropsia 29 bovinos. Os locais mais acometidos foram as vértebras T3-L3 (46%, 23/50), C1-C5 (22%, 11/50), C6-T2 (14%, 7/50), sacrococcígea (4%, 2/50) e L4-S2 (2%, 1/50); cérebro (8%, 4/50) e cerebelo (4%, 2/50). A idade dos bovinos afetados variou de 20 dias a 16 anos, com maior ocorrência em animais com menos de 12 meses (56%, 28/50). As fêmeas foram mais acometidas (58%, 29/50) do que os machos (42%, 21/50). Os sinais clínicos variaram de acordo com a localização da lesão e foram representados principalmente por ataxia, paresia ou paralisia dos membros, incapacidade de se levantar e de ficar em estação, alterações posturais, hiperestesia nas extremidades, além de perda da sensibilidade cutânea relacionada com a localização da lesão. Os achados de necropsia revelaram alterações como abscessos no corpo vertebral, no espaço intervertebral, no canal medular, para-hipofisário e no cerebelo; granuloma no arco da vértebra, fraturas do corpo das vértebras; hematoma subaracnoide; alteração óssea congênita causando compressão medular e espondilite. Anamnese detalhada e exame clínico do SNC, associados aos achados de necropsia foram importantes para determinar a causa da doença, correlacionar com o quadro clínico e localizar os segmentos acometidos do SNC dos bovinos. Torna-se importante incluir estas enfermidades na lista de diagnósticos diferenciais em bovinos que apresentem sintomatologia nervosa.

Anatomopathological alterations and destinations of cattle carcass in Brazil ­2017 to 2019 / Alterações anatomopatológicas e destinos das carcaças bovinas no Brasil -2017 a 2019

Brazil is a major beef producer and exporter. However, carcasses with anatomopathological alterations can cause economic losses by being the target of some type of condemnation or being conditionally used. The objective of this research work was to analyze the anatomopathological changes and destinations of bovine carcasses in Brazil, from March 30, 2017, to December 31, 2019. Data were collected through the Management Information System of the Federal Inspection Service (SIGSIF), made available online by the Brazilian Ministry of Agriculture, Livestock and Supply (MAPA). It was observed that 67,456,321 bovines were slaughtered, and 2.0% of the carcasses were condemned or conditionally used. The southern region of the country had the highest occurrence of anatomopathological alterations in the carcasses (4.5%), while the Northeast had the lowest (0.1%). The main criterion for judging carcasses in the country was partial condemnation, with 81.7% of judgments established. The main causes of condemnations and conditional use were contamination (31.5%), cysticercosis (21.2%), contusion (11.3%), adenitis (7.4%) and abscess (6.5%). It was noted that a standardization of records in the SIGSIF would be important for a clearer collection of information and for the recording itself by slaughterhouses. The importance of veterinary inspection to guarantee the commercialization of safe meats to consumers was evidenced.

O Brasil é um grande produtor e exportador de carne bovina. Entretanto, carcaças com alterações anatomopatológicas podem causar prejuízos econômicos por receberem algum tipo de condenação ou aproveitamento condicional. O objetivo do trabalho foi analisar as alterações anatomopatológicas e os destinos dados as carcaças bovinas no Brasil, no período de 30 de março de 2017 a 31 de dezembro de 2019. Os dados foram coletados por meio do Sistema de Informações Gerenciais do Serviço de Inspeção Federal (SIGSIF), disponível online por meio do MAPA. Observou-se que foram abatidos 67.456.321 bovinos e 2,0% das carcaças foram condenadas ou aproveitadas condicionalmente. A região Sul do país obteve maior ocorrência de alterações anatomopatológicas nas carcaças (4,5%), enquanto o Nordeste obteve a menor (0,1%). O principal critério de julgamento de carcaças no país foi a condenação parcial, com 81,7% dos julgamentos estabelecidos. As principais causas de condenações e aproveitamento condicional foram contaminação (31,5%), cisticercose (21,2%), contusão (11,3%), adenite (7,4%) e abcesso (6,5%). Notou-se que a padronização dos registros no SIGSIF seria importante para coleta mais clara das informações e para o próprio registro por parte dos abatedouros. Evidenciou-se a importância da inspeção veterinária para garantir a comercialização de carnes seguras aos consumidores.

Slaughter condemnation in bovine due to parasitic lesions and their economic impact in Federal Inspection System establishments in Brazil and in State inspection System in Rio Grande do Sul State / Condenação ao abate em bovinos devido a lesões parasitárias e seu impacto econômico em estabelecimentos do Sistema Federal de Inspeção no Brasil e no Sistema Estadual de Inspeção no Rio Grande do Sul

Slaughter condemnations are important sources of information on cattle health. The incidence of bovine parasitic diseases is still very high in Brazil. These diseases, in addition to causing harm to the animals health, are neglected zoonotic diseases in several parts of world. The study analysed not only the Carcass losses, but also the economic damage resulting from slaughter condemnations due to parasitic causes. Cattle slaughter data from the Brazilian Ministry of Agriculture, Livestock and Supply (MAPA), over the period of 2012 to 2015 and data from the Secretary of Livestock and Irrigation of the state of Rio Grande do Sul (SEAPI-RS) were analyzed between 2014 and 2018.The number of organs and carcasses condemned was multiplied by the respective values (in Brazilian Real) obtained from slaughterhouses and subsequently converted into dollars. Brazilian analysis in SIF (Federal Inspection System) establishments showed that more than 1.2 million organs (3,884,505 kg) and 20,000 carcasses (4,547,718 kg) were condemned only due to parasitic causes during post-mortem inspection. In Rio Grande do Sul, in state inspection establishments, more than 1.7 million organs (8,210,559 kg) and 5,000 carcasses (1,243,200 kg) were condemned. These data are alarming and support the need for public policies to control these parasitic diseases.(AU)

Condenações durante o abate são importantes fontes de informação sobre a sanidade dos rebanhos. Ainda são altas as incidências de doenças parasitárias, as quais trazem consequências à saúde dos animais, são zoonoses e têm sua importância negligenciada em diversos países. O estudo objetivou quantificar não apenas as perdas encontradas, mas o prejuízo econômico resultante das condenações ao abate por causas parasitárias. Para isso foram analisados dados de abate de bovinos do Ministério da Agricultura Pecuária e Abastecimento, no período de 2012 a 2015, e dados da Secretaria da Agricultura Pecuária e Irrigação, do estado do Rio Grande do Sul, no período de 2014 a 2018. A quantidade de órgãos e carcaças condenados foi multiplicada pelos respectivos valores (em Reais), obtidos da indústria frigorífica e, posteriormente, convertidos para dólar. A análise brasileira de estabelecimentos com SIF (Serviço de Inspeção Federal) mostrou que mais de 1,2 milhão de órgãos (3.884.505 kg) e 20 mil carcaças (4.547.718 kg) foram condenados devido a causas parasitárias durante a inspeção. No estado do Rio Grande do Sul, nos estabelecimentos de inspeção estadual, foram condenados mais de 1,7 milhão de órgãos (8.210.559 kg) e 5 mil carcaças (1.243.200 kg). Os dados são alarmantes e ressaltam a necessidade de políticas públicas para controlar estas parasitoses.(AU)

Human post exposure anti-rabies prophylactic assistance in the south of Brazil / Assistência profilática anti-rábica pós-exposição humana no sul do Brasil

Rabies is a zoonosis caused by Lyssavirus, with progressive development and a high lethality rate. In Brazil, rabies and accidents caused by animals potentially transmitting the disease are mandatory notification injuries. Exposure to rabies infection places a high financial burden on public health systems, especially for the care of people who are exposed and have a high risk of death. We aimed to define the epidemiological profile of human rabies post-exposure assistance in the municipality of Santa Maria, Rio Grande do Sul, Brazil, from 2010 to 2015. Data from Brazil's Notifiable Diseases Information System were obtained and analyzed; these data were acquired by the completion of individual inquiry forms querying human antirabies assistance. A total of 55% (1,898/3,453) of anti-rabies assistance cases involved women and 45%(1,555/3,453) men. The highest occurrence (54.5%-1,882/3,453) was in the age group of 20–59 years. Most registered cases (87.5%–3,024/3.453) were caused by dogs, followed by cats (10.9%–378/3,453). The lower limb (22.1%–617/2,790) was the area of the body with the highest number of canine bites. We observed incorrect indications for the treatment. We suggest further training for health professionals involved in rabies post-exposure prophylaxis care, and dissemination of information aimed at educating users about the importance of animal-related injuries.

A raiva é uma zoonose causada por Lyssavirus, com desenvolvimento progressivo e alta taxa de letalidade. No Brasil, a raiva e os acidentes causados por animais potencialmente transmissores da doença, são agravos de notificação obrigatória. A exposição à infecção por raiva coloca um alto ônus financeiro para o sistema público de saúde, especialmente para o atendimento de pessoas expostas e com alto risco de morte. O objetivo deste estudo foi definir o perfil epidemiológico da assistência pós-exposição à raiva humana no município de Santa Maria, Rio Grande do Sul, Brasil, de 2010 a 2015. Foram obtidos e analisados os dados do Sistema de Informações sobre Doenças Notificáveis do Brasil (SINAM); adquiridos por meio do preenchimento de formulários de consulta individuais, verificando a assistência antirrábica humana. Um total de 55% (1.898/3.453) e 45% (1.555/3.453) dos casos de assistência anti-rábica envolveu mulheres e homens respectivamente, com maior ocorrência na faixa etária de 20 a 59 anos (54,5% - 1.882/3.453). A maioria dos casos registrados (87,5% - 3.024/3.453) foi causada por cães e 10,9% (378/3.453) por gatos. O membro inferior (22,1% - 617/2.790) foi a área do corpo com o maior número de agressões por cães. Desta forma, sugere-se o treinamento para profissionais de saúde envolvidos no tratamento profilático da raiva após a exposição e disseminação de informações destinadas a educar os usuários sobre a importância das lesões relacionadas a animais.

Most registered cases (87.5%–3,024/3.453) were caused by dogs, followed by cats (10.9%–378/3,453). The lower limb (22.1%–617/2,790) was the area of the body with the highest number of canine bites. We observed incorrect indications for the treatment. We suggest further training for health professionals involved in rabies post-exposure prophylaxis care, and dissemination of information aimed at educating users about the importance of animal-related injuries.(AU)

A raiva é uma zoonose causada por Lyssavirus, com desenvolvimento progressivo e alta taxa de letalidade. No Brasil, a raiva e os acidentes causados por animais potencialmente transmissores da doença, são agravos de notificação obrigatória. A exposição à infecção por raiva coloca um alto ônus financeiro para o sistema público de saúde, especialmente para o atendimento de pessoas expostas e com alto risco de morte. O objetivo deste estudo foi definir o perfil epidemiológico da assistência pós-exposição à raiva humana no município de Santa Maria, Rio Grande do Sul, Brasil, de 2010 a 2015. Foram obtidos e analisados os dados do Sistema de Informações sobre Doenças Notificáveis do Brasil (SINAM); adquiridos por meio do preenchimento de formulários de consulta individuais, verificando a assistência antirrábica humana. Um total de 55% (1.898/3.453) e 45% (1.555/3.453) dos casos de assistência anti-rábica envolveu mulheres e homens respectivamente, com maior ocorrência na faixa etária de 20 a 59 anos (54,5% - 1.882/3.453). A maioria dos casos registrados (87,5% - 3.024/3.453) foi causada por cães e 10,9% (378/3.453) por gatos. O membro inferior (22,1% - 617/2.790) foi a área do corpo com o maior número de agressões por cães. Desta forma, sugere-se o treinamento para profissionais de saúde envolvidos no tratamento profilático da raiva após a exposição e disseminação de informações destinadas a educar os usuários sobre a importância das lesões relacionadas a animais.(AU)

Cenurose em ovino com sinais neurológicos - diagnóstico com tomografia computadorizada / Cenurosis in a sheep with neurological signs - diagnosis with computed tomography

Background: Cenurosis is a parasitic disease caused by Coenurus cerebralis, an intermediate form of Taenia multiceps multiceps, causing a fatal disease in production animals. Its adult form (Taenia) lodges in the small intestine of canids and can infect several intermediate hosts. Sheep are the main species affected by the disease, having nervous symptoms as one of its manifestations. This study aimed to describe the changes observed in computed tomography, as well as the clinical findings of a case of Cenurosis in a sheep on the western border of Rio Grande do Sul. Case: A ram was referred to the Centro Universitário da Região da Campanha (URCAMP) with neurological signs. Clinical, hematological, radiographic, tomographic and necroscopic evaluation of the animal was performed. There were no significant hematological and radiographic changes. During the neurological examination, corneal opacity was found in the right eyeball, associated with a visual deficit in the same eye. Also, when stimulated to move, it was possible to observe ataxia with ambulation to the left side, with right lateral displacement of the head. The tomography showed a hypodense area of approximately 3 cm at the base of the brain, in the region of the thalamus and third ventricle. Macroscopically, a translucent spherical cyst with approximately 4 cm in diameter was observed, containing the protoescolex/scolices of Taenia multiceps in the same region. Discussion: Computed tomography identified the presence of an apparently circular volume of approximately 4 cm in diameter, causing ventricular dilatation. This evidence of ventricular dilation corroborates aspects described in the literature, which found bilateral dilation of the ventricles by compression promoted by a cyst in the 4th ventricle. As the location of the cyst was located at the base of the brain, in the region of the third ventricle, it would be difficult to perform the surgery in the treatment of this case. Signs of ataxia, walking movements, decreased reflexes, nystagmus, unilateral blindness and lateral decubitus are commonly observed. Reports described that the main neurological alterations observed in 20 sheep with cenurosis were postural deficit, locomotion alteration, visual deficit and behavioral alterations, with more than 50% of the animals showing at least one of these signs. The main neurological signs observed in the case described were changes in gait, with walking, blindness, lateral head deviation and ataxia. These signs guide the clinical diagnosis of cenurosis. At necropsy, a spherical translucent cyst with approximately 4 cm in diameter was observed, containing the protoescolex/scolices of Taenia multiceps, which extended dorsally from the third ventricle to the base of the thalamus, laterally displaced to the right side. Rostrocaudal the lesion extended rostrally across the entire length of the thalamus to the beginning of the caudate nucleus and caudally to the base of the caudal colliculus, causing compression of the adjacent parenchyma, enabling the diagnosis of cenurosis. Similar findings are described as Coenurus cerebralis. This lesion pattern macroscopically characterizes the parasite lesions. Thus, it is concluded that the visualization of a hypodense area in CNS regions of sheep with neurological signs allows the diagnosis of cenurosis and precise location of the lesion. The description of this case adds information so that other professionals in the field can be successful in diagnosing the disease.

First detection of diarrheagenic Escherichia coli pathotypes in the Mearim River Watershed, Maranhão State, Brazil / Primeira detecção de patótipos diarreiogênicos de Escherichia coli na Bacia Hidrográfica do Rio Mearim, Estado do Maranhão, Brasil

The Mearim River Watershed has multiple uses e.g. leisure, navigation, fishing and subsistence agriculture and constitutes the main source of supply for the populations of municipalities situated along its course. In addition to being a water supply source, the existence of the 'pororoca' (tidal bore) effect in a stretch of the lower course of the Mearim River attracts people from several Brazilian states and different countries, as it offers excellent conditions for surfing in fresh water. In this respect, given the importance of the watershed, this study was developed to report the detection of diarrheagenic Escherichia coli pathotypes in a stretch of the lower course of the Mearim River, located in the state of Maranhão, Brazil. Thirty water samples were collected from 10 sampling points. To quantify E. coli, the chromogenic enzymatic system was used and positive samples were isolated and biochemically identified. Pure cultures underwent DNA extraction by heating followed by polymerase chain reaction (PCR) characterization. At the time of the collections, an observation schedule was used to record information on the existence of rearing of livestock and domestic animals; businesses; residences; and fruit and vegetable farming on the riverbanks. The samples were analyzed for the mean populations of E. coli, which ranged from 444 to 2,585 MPN mL-1. Twenty bacterial isolates were identified and the diarrheal pathotypes ETEC, typical EPEC and atypical EPEC were detected. The detection of these pathotypes can represent an epidemiological risk and compromise several uses of this water resource, such as irrigation of fruits and vegetables consumed raw, fishing, animal watering and recreation. Structural investments in basic sanitation are essential to minimize environmental degradation resulting from anthropic activities and to act preventively in public health. In addition, the recovery of riparian forests along the watershed and the maintenance of vegetation in these areas are measures to reduce the transport of particles from the soil to the watercourses, improving the qualitative and quantitative characteristics of this water resource.(AU)

A Bacia Hidrográfica do Rio Mearim apresenta múltiplos usos - lazer, navegação, pesca e agricultura de subsistência - e constitui a principal fonte de abastecimento para as populações dos municípios inseridos em seu curso. Além de fonte hídrica de abastecimento, a existência do efeito pororoca em um trecho do baixo curso do Rio Mearim atrai pessoas de vários estados brasileiros e diferentes países, pois apresenta excelentes condições para a prática de surfe em água doce. Nesse sentido, considerando a importância da Bacia Hidrográfica, objetivou-se relatar a detecção de patótipos diarreiogênicos de Escherichia coli em um trecho do baixo curso do rio Mearim, localizado no estado do Maranhão. Para isso, foram realizadas coletas de 30 amostras de água em 10 pontos amostrais. Para a quantificação de E. coli utilizou-se o sistema cromogênico enzimático e das amostras positivas procedeu-se ao isolamento e identificação bioquímica dos isolados. A extração do DNA das culturas puras foi realizada por aquecimento seguido da caracterização por reação em cadeia da polimerase (PCR). No momento das coletas utilizou-se uma pauta de observação para anotação de informações sobre a existência de criação de animais de interesse pecuário e doméstico, empreendimentos comerciais, residências e cultivo de frutas e hortaliças nas margens do rio. Nas amostras analisadas, foram quantificadas populações médias de E. coli que variaram de 444 a 2.585 NMP.mL-1, identificados 20 isolados bacterianos e detectados os patótipos diarreiogênicos ETEC, EPEC-típica e EPEC-atípica. A detecção destes patótipos pode representar risco epidemiológico e compromete diversos usos desse recurso hídrico, como a irrigação de frutas e hortaliças ingeridas cruas, pesca, dessedentação animal e recreação. Investimentos estruturais em saneamento básico são fundamentais para minimizar a degradação ambiental resultante das atividades antrópicas e para atuar preventivamente na saúde pública. Adicionalmente, a recuperação das matas ciliares ao longo da Bacia Hidrográfica e manutenção da vegetação nestas áreas são medidas para a redução do transporte de partículas do solo para os cursos d'água, e em consequência, acarretará na melhoria das características quali-quantitativas desse recurso hídrico.(AU)

Abortamento por Neospora caninum em bovinos de leite no sul de Santa Catarina, Brasil / Abortion due to Neospora caninum in dairy cattle in Southern Santa Catarina state, Brazil

Background: Neosporosis is a cosmopolitan disease known as the main infectious cause of abortion in cattle, reported in several states in Brazil. The transplacental transmission in cattle is responsible for perpetuating the disease in the herd. In the state of Santa Catarina, previous studies on this protozoan in cattle are mostly serological surveys. To increase information about this reproductive disorder, this work describes the diagnosis of abortions due to Neospora caninum in dairy cattle from state of Santa Catarina and the follow-up for 4 years in a farm affected by neosporosis. Cases: From 2015 to 2019, necropsy was performed on 10 aborted bovine fetuses, between fifth and eighth month of pregnancy, with 1 fetus aborted in 2015, 3 in 2016, 2 in 2017 and, 4 in 2019, all originating from the same dairy property in the southern region of state of Santa Catarina. No macroscopic lesions were found. Histopathology revealed mild to moderate multifocal mononuclear necrotizing encephalitis in 5 fetuses, and multifocal mild mononuclear myositis and myocarditis in 4 and 3 fetuses, respectively. Polymerase Chain Reaction (PCR) using primers based on the Nc-5 gene was positive for N. caninum in five fetuses. Three visits were performed in the farm for epidemiological evaluation and blood samples collection for IgG antibodies anti-N. caninum (IFAT). The total herd was 170 Jersey, Holstein and crossbred cattle, raised in a semi-confined system with mechanical milking system. Since 2014, there has been a significant increase in abortions cases, approximately 20 cows had abortions; in the year 2015, approximately 10; in 2016, less than 5; in 2017, 4 cows aborted; in 2018, 11 abortions and, in 2019, there were 4 abortions. An increase in the rate of return to estrus was also reported, and both primiparous and multiparous cows had reproductive disorders. Abortions were recorded throughout the year and occurred predominantly between the fourth and sixth month of pregnancy. In 2016, an Indirect Immunofluorescence Reaction (IFAT) was performed on sera from 26 cows (13 with a history of reproductive disorders and another 13 without disorders). Of these, 50.0% (13/26) were seropositive, with titers ranging from 100 to 1600 (cutoff ≥100). The Enzyme Immunoassay (ELISA) of the entire herd was carried out in 2017, with 26.54% (43/162) of seropositivity, 8.02% (13/162) suspect, and 30.4% (17/56) had reproductive disorders. It was observed that only animals born on the property were used for replacement, there was less possibility of direct contact between dogs on the property with milking facilities, placental and fetal remains, properly disposing of these, incinerating or burying. Thirty animals were discarded from the property, 25 of which had reproductive disorders. All young female daughters of seropositive cows remained on the property for replacement. During the evaluation period, all dogs were eliminated. Discussion: In this study, the diagnosis of neosporosis was made through epidemiology, histopathological lesions characterized by mononuclear encephalitis, myocarditis and myositis, and detection of the agent by PCR, associated with serological techniques. The lesions observed are indicative of N. caninum infection and are compatible with lesions observed in other studies. Serological screening is important to complement the diagnosis of abortion by N. caninum and to help control the agent in herds. From this report it is concluded that N. caninum is an important agent of reproductive disorders in cattle in the southern region of Santa Catarina, the different serological analyzes showed a good screening index for the inclusion of control strategies. In addition, the monitoring of reproductive rates of affected properties becomes necessary over the years, allowing better observation of control strategies.

Endosurgery approach in a dog with thoracoabdominal injury

Background: Chest trauma is one of the main thoracic injuries in dogs and cats, reaching a high morbidity and mortality. The tissue damage, in thoracic trauma, can be underappreciated by visual exam and traditional radiography. The thoracoscopy can provide information for a precise definitive diagnosis, by this technique bleeding or air leakage can be identified and corrected immediately and the diaphragm can be completely evaluated. The aim of this work was to describe the thoracoscopic approach in a case of diaphragmatic perforation caused by penetrating trauma in a dog. Case: A 6-year-old male dog mixed-breed dog, weighing 14 kg with thorax perforation was presented to the Veterinary Hospital. Clinical examination of the animal revealed the following: pale mucous membranes, moderate dyspnea, open pneumothorax, abdominal distension, heart rate of 108 beats per minute and respiratory rate of 64 breaths per minute. Physical examination confirmed a 3 cm perforation hemorrhagic lesion in the left ninth intercostal space. As an emergency treatment, oxygen therapy, tramadol hydrochloride [Cronidor® 2%, 4 mg/kg, i.v, TID], tranexamic acid [Transamin® 25 mg/kg, i.v, TID], ceftriaxone [Rocefin® 50 mg/kg, i.v, BID] and fluid therapy with lactated Ringer's solution were administered. The hair was removed, and then, wound cleaning and obliteration of the wall injury with sterile gauze was performed. After the emergency stabilization, the animal was anesthetized, followed by preventive thoracocentesis by an approach close to thoracic perforation and thoracoscopy without pneumoperitonea through this thoracic perforation with 0-degree rigid endoscope. About 100 mL of blood and air was drained and diagnosed perforation in the diaphragm and pulmonary atelectasis in the caudal and left cranial lobes. the edges of the incisional wound were debrided, and the closure of thoracic incision was performed usual way. After that, the air was removed by a catheter and syringe system. A flexible plastic tube was inserted through the chest wall and into the pleural space for drainage every 2 h for 24 h. There were no intercurrences during the first 24 h after the surgical procedure. The patient was discharged 48 h after the surgery. Cephalexin [75 mg, 30 mg/kg, v.o, TID, during 5 days), Ketoprofen [20 mg, 2 mg/kg, v.o, SID, during 5 days], Tramadol Hydrochloride [50 mg, 4 mg/kg, v.o, SID, during 2 days] and Rifamycin spray at the wound site was prescribed. Ten days after surgery, the patient returned to the hospital for suture removal and reassessment. Discussion: The prognosis of chest perforation depends on the severity and number of internal and external thoracic lesions, as well as cardiovascular status at the time of initial patient care. In cases of penetrating chest trauma, it is essential to thoroughly examine the thoracic cavity for bleeding, tissue tears, and diaphragm perforation. The use of the endoscope allowed for a more detailed exploration of the chest without the need to increase the incision. When the diaphragm lesion was found, it was also possible to perform the abdominal examination by videoendoscopy, through this perforation. Laparotomy and thoracotomy cause postoperative pain and discomfort, in addition to increasing recovery time, however, even with trauma, not performing a larger incision favored the recovery of this patient, without any intercurrence in the first 24 h after the procedure. In conclusion, the endoscopic approach was efficient for diagnosis, avoiding greater trauma and contributing to a better clinical recovery of the patient.

Open legacy soil survey data in Brazil: geospatial data quality and how to improve it

Spatial soil data applications require sound geospatial data including coordinates and a coordinate reference system. However, when it comes to legacy soil data we frequently find them to be missing or incorrect. This paper assesses the quality of the geospatial data of legacy soil observations in Brazil, and evaluates geospatial data sources (survey reports, maps, spatial data infrastructures, web mapping services) and expert knowledge as a means to fix inconsistencies. The analyses included several consistency checks performed on 6,195 observations from the Brazilian Soil Information System. The positional accuracy of geospatial data sources was estimated so as to obtain an indication of the quality for fixing inconsistencies. The coordinates of 20 soil observations, estimated using the web mapping service, were validated with the true coordinates measured in the field. Overall, inconsistencies of different types and magnitudes were found in half of the observations, causing mild to severe misplacements. The involuntary substitution of symbols and numeric characters with similar appearance when recording geospatial data was the most common typing mistake. Among the geospatial data sources, the web mapping service was the most useful, due to operational advantages and lower positional error (~6 m). However, the quality of the description of the observation location controls the accuracy of estimated coordinates. Thus, the error of coordinates estimated using the web mapping service ranged between 30 and 1000 m. This is equivalent to coordinates measured from arc-seconds to arc-minutes, respectively. Under this scenario, the feedback from soil survey experts is crucial to improving the quality of geospatial data.

Dissimilarity of parameterized maps generated in geostatistics and the assumption of an automatic software model in precision agriculture / Dissimilaridade de mapas gerados na geoestatística parametrizada e seu pressuposto modelo automático de software na agricultura de precisão

Geostatistics is the main technique used to efficiently determine spatial variability. The objective of this study was to evaluate the applicability of the principles of geostatistics in the use of semivariograms elaborated through parametric monitoring and the assumption automatically made by software in the map preparation of soil chemical attributes. Available phosphorus (P), potassium (K+), calcium (Ca²+), magnesium (Mg²+), base saturation (V%), sulfur (SO4²-), and pH were compared from the soil chemical attributes of 60 samples of a Typical Oxisol collected at a 0-20 cm depth and a distance of 300 m betweenthe points. The maps were compared using error matrices and evaluated by the Global Accuracy (GA), Kappa (K), and Tau (T) indexes. The parameterized semivariograms and the automatic software model assumption did not present a high coincidence for the available P and Mg²+, making it necessary to adjust the semivariogram variables in the spatial analysis as a function of the outliers, sum of squares of residuals, coefficient of determination, and cross-validation to better represent the variability of the data and thus avoid distortions of the sample point range that would affect the adequate representativeness of the attributes, which contrasts with the automatic model generated by the software.

A geoestatística é uma das principais técnicas utilizadas para determinar a variabilidade espacial dos atributos do solo. O objetivo deste trabalho foi comparar o uso de semivariogramas elaborados através do acompanhamento paramétrico da geoestatística e seu pressuposto modelo realizado automaticamente por software na confecção dos mapas de fertilidade do solo. Foram comparados os mapas dos valores de pH, fósforo (P), potássio (K+), cálcio (Ca²+), magnésio (Mg²+), enxofre (SO4²-) e saturação por bases (V%), provenientes de 60 amostras coletadas de área de Latossolo Vermelho Distrófico coletadas na profundidade 0-20 cm e malha de 300 m de distância entre os pontos. Os mapas foram comparados por matrizes de erro e avaliadas pelos índices Exatidão Global, Kappa e Tau. O uso de semivariogramas parametrizados e seu pressuposto modelo automático do software não apresentaram alta coincidência para os teores de P disponível e Mg²+, sendo necessário ajustes das variáveis dos semivariogramas na análise espacial em função dos outliers, soma dos quadrados dos resíduos, coeficiente de determinação e validação cruzada para melhor representação da variabilidade dos dados e assim, evitar distorções do alcance do ponto amostral para uma boa representatividade dos atributos estudados, o que contraria o modelo automático gerado pelo software.
