Factors associated with small ruminant lentivirus infection in goat herds from Pernambuco state, Northeast region of Brazil.

Serum samples (n = 1532) were collected between May 2011 to April 2012 from goats from 76 herds (49 from dairy farms and 27 herds for genetic improvement) from three geographical regions from the state of Pernambuco, Brazil: Zona da Mata, Agreste, and Sertão. Samples were processed using agar gel immunodiffusion test, with p28 CAEV antigen. The objective was to determine the risk factors for small ruminant lentivirus (SRLV) in dairy goats and goats with high genetic value. Overall, seroprevalence was 13.7% (210/1532) [95% CI: 12-15.4%] in animals and 67.1% (51/76) [95% CI: 56.5%- 77.7%] in herds. In dairy farms the seroprevalence was 73.5% (36/49) [95% CI: 61.1%- 85.8%], and in properties with animals of high genetic value it was 55.6% (15/27) [95% CI: 36.8%- 74.3%]. Robust Poisson regression analysis adjusted by the random effect of the herd showed that risk factors were: importing bucks from another Brazilian state (prevalence ratio [PR] = 4.73 [95% CI: 2.05; 10.88]), not isolating sick animals (PR = 3.27 [95% CI: 2.24; 4.76]), and participating in fairs/animal crowding (PR = 1.52 [95% CI: 1.09; 2.11]). Prevalence results show that SRLV is present in caprine herds in the state of Pernambuco and identified risk factors are strongly related to animal transit. Considering the epidemiological situation, the first step for mitigating the consequences of this disease would be controlling animal transit.

Clinical and surgical aspects of hypospadia and urethral diverticulum in goats / Aspectos clínicos e cirúrgicos de hipospadia e divertículo uretal em caprinos

Hypospadia is the imperfect closure of the external urethra of the male which results from the incomplete fusion of the urogenital folds and abnormal openings of the penile urethra. The urethral diverticulum is the abnormal dilatation of the urethra, and can be of multifactorial origin and related to genetic, endocrinological and environmental factors. The objective of this article is to report on the clinical and surgical treatment of two cases of hypospadias and one case of urethral diverticulum in goats raised as pets, originated from cross breeding polled pairs. In Case 1 the hypospadias was characterized by two orifices on the ventral portion of the penis, separated by a 2 cm interruption of the urethra, and in Case 2 by an orifice on the ventral portion in the region of the urethra. In both cases there was an accumulation of urine in the middle ventral region of the foreskin, leading to distension of the skin. Both cases were successfully treated by urethrostomy and partial penectomy with fixation of the proximal urethral ostium to the skin. In Case 3, the animal was seen at ten days of age with presence of a diverticulum in the preputial region, however, the animal returned for new care only after four months due to urethral obstruction and died as a result of advanced azotemia. Surgical treatment of hypospadia, when performed before the development of azotemia associated with urinary retention, has been shown to be efficient, and post-operative care is important

Hipospadia é o fechamento imperfeito da uretra externa do macho, resultado da falha de fusão das pregas urogenitais e da formação incompleta da uretra peniana e o divertículo uretral é a dilatação anormal da uretra, podendo ser de origem multifatorial e relacionada a fatores genéticos, endocrinológicos e ambientais. O objetivo desse artigo é relatar o tratamento clínico-cirúrgico de dois casos de hipospadia e um de divertículo uretral em caprinos criados como animais de estimação, oriundos de cruzamentos de casal mocho. No Caso 1 a hipospadia era caracterizada por dois orifícios ventrais ao pênis, separados por uma interrupção de 2 cm da uretra e no Caso 2 por um orifício na face ventral na região da uretra, em ambos os casos ocorreu o acúmulo de urina na região médio ventral do prepúcio levando a distensão da pele. Os dois casos foram tratados com sucesso através da uretrostomia e penectomia parcial com fixação do óstio uretral proximal a pele. Já no Caso 3, o animal foi atendido com dez dias de vida com presença de divertículo na região prepucial, no entanto retornou para novo atendimento somente após quatro meses devido obstrução uretral, causando quadro grave de azotemia e a morte. O tratamento cirúrgico da hipospadia, quando realizada antes do desenvolvimento de azotemia associado a retenção urinária, mostrou-se eficiente, sendo importante atenção os cuidados pós-operatórios

Molecular characterization of ureaplasmas isolated from reproductive tract of goats and sheep from Brazil.

Ovine/caprine ureaplasmas have not yet been assigned a species designation, but they have been classified into nine serotypes. Herein ureaplasmas were searched for in 120 samples of vulvo vaginal mucous from sheep and 98 samples from goats at 17 farms. In addition, semen samples were collected from 11 sheep and 23 goats. The recovered ureaplasma were from sheep and goats from animals without any reproductive disorder symptoms, but not all animals presented positive cultures. In sheep, 17 (68%) cultures of vulvovaginal mucous were positive for ureaplasma and 11 (27%) samples of semen presented positive cultures in animals with clinical signs of orchitis, balanoposthitis or low sperm motility. In goats four ureaplasma isolates were obtained from vulvovaginal mucus, but the semen samples were all negative. The isolates were submitted to Pulsed-field gel electrophoresis methodology and their 16S rRNA genes were sequenced. Fifty percent of ureaplasma recovered from sheep allowed for PFGE typing. Eleven isolates showed eight profiles genetically close to the bovine ureaplasmas. The 16S rRNA gene sequencing showed differences or similarities of isolates from sheep and goats, and the reference strains of bovine and human ureaplasma. Four clinical isolates from sheep were grouped separately. The studied ureaplasma isolates showed to be a diverse group of mollicutes.

Susceptibilidade a antimicrobianos de bactérias isoladas de leite caprino em Sergipe - Brasil / Antimicrobial susceptibility of bacteria isolated from goat milk in Sergipe - Brazil

Background: Bacterial resistance is a fundamental aspect of One Health, which is defined as the inseparable unity of animal, human, and environmental health. Epidemiological surveillance on the spread of bacterial resistance in animals and their derived products is essential given that meat, milk, and dairy products can carry resistant microorganisms that may reach humans through the food chain either by direct consumption or by handling the product. To eliminate the scarcity of information, it is necessary to characterize the epidemiological situation in terms of bacterial resistance in dairy production in northeastern Brazil. Thus, the objective of this study was to determine the frequency and antimicrobial susceptibility profile of bacteria isolated from goat milk samples from some municipalities in the Brazilian state of Sergipe. Materials, Methods & Results: The study included 28 goat farms in 4 municipalities of the Semiarid region of the State of Sergipe in Northeastern Brazil, namely Canindé de São Francisco (n = 11), Nossa Senhora da Glória (n = 6), Poço Verde (n = 6), and Porto da Folha (n = 5). All lactating does of each herd (n = 263) aged >1 year were, sampled randomly by non-probabilistic convenience sampling. Milk samples were collected from both teats, resulting in 526 samples in total. Bacterial culturing and isolation were performed, followed by antimicrobial susceptibility profile analysis to the following active principles: amoxicillin with and without clavulanic acid, amikacin, ampicillin with sulbactam, ciprofloxacin, cefalexin, cefalotin, ceftriaxone, chloramphenicol, doxycycline, enrofloxacin, gentamicin, levofloxacin, ofloxacin, penicillin G, and tetracycline. A survey form was used to obtain zootechnical information for each farm. Data are described as absolute and relative frequencies. The significance assessment of the differences between herd characteristics and bacterial isolation was performed using Pearson's chi-squared test. Bacterial isolation occurred in 15.4% (81/526) of the samples from 23.2% (61/263) of the goats. Escherichia coli (45.9% = 28/61), Staphylococcus caprae (16.4% = 10/61) and Enterococcus faecalis (11.5% = 7/61), were the most frequently isolated species. Bacterial isolations were predominant in dairy herds with up to 50 animals, production of 20 to 50 L/day and in the municipality of Porto da Folha. In terms of antimicrobial susceptibility, most isolates demonstrated resistance to penicillin and amoxicillin (88.5%), followed by ceftriaxone (23%), ofloxacin (23%), tetracycline (23%), doxycycline (19.7%), chloramphenicol (11.5%), levofloxacin (11.5%), ampicillin/ sulbactam (8.2%), amikacin (6.6%), cephalothin (4.9%), cephalexin (3.3%) and gentamicin (3.3%). Approximately 20% of the isolates were multidrug resistant, especially E. coli (50%) and S. aureus (16.7%). Discussion: E. coli was the most frequently isolated species from the samples. It is considered an environmental pathogen, and its high frequency in different herds indicates poor milking hygiene. E. coli also stood out as the species presenting the most multidrug-resistant (MDR) isolates (50%), with strains resistant to beta-lactams, aminoglycosides, quinolones, tetracycline, and chloramphenicol. Coagulase-negative staphylococci are recognized as a public health problem as they are etiological agents of various diseases and can easily acquire antimicrobial resistance genes. Although it was not the most frequently isolated species, S. aureus was the species with the second-highest frequency of MDR strains. The presence of MDR species is relevant and indicates the need for urgent action to reduce the dissemination of antimicrobial resistance. Relevant steps must be taken jointly by professionals involved in human, animal, and environmental health.

Comparação entre diferentes técnicas empregadas na conservação e manutenção de peças anatômicas / Comparison between different techniques used in the conservation and maintenance of anatomical parts

Dentre as diversas formas de obter a conservação de peças anatômicas para estudo, a formolização é a mais utilizada. Esta técnica altera a coloração e textura, dificultando o processo de ensino-aprendizagem. Além disso, proporciona um ambiente insalubre que pode comprometer a saúde de indivíduos expostos constantemente ao formol. Existem técnicas alternativas como a glicerinação, criodesidratação e corrosão, as quais reduzem os riscos à saúde ocasionados pela exposição aos materiais, proporcionam um ambiente livre de odores desagradáveis e facilitam a manipulação e o armazenamento das peças, quando comparadas com a formolização. O presente trabalho visa à apresentação de técnicas alternativas para a conservação e manutenção de peças anatômicas e seus devidos procedimentos, buscando a substituição da utilização do formol como forma principal de conservação. A técnica de glicerinação apresenta grande eficiência quanto à preservação das características de coloração e formato das vísceras, além de ser uma técnica de baixo custo e não apresentar riscos à saúde, assim como a técnica de criodesidratação, a criodesidratação difere em relação à tonalidade das vísceras, entretanto demonstra facilidade quanto à conservação, armazenamento e manutenção das mesmas. Já a injeção e corrosão de órgãos facilitam a visualização da arquitetura interna de órgãos ocos, além de permitir fazer o modelo de vascularização de órgãos. No entanto, esta pode ser considerada uma técnica cara a depender do polímero utilizado.

Among the several ways to obtain the conservation of anatomical parts for study, formalization is the most used. This technique changes the color and texture, making the teaching-learning process difficult. In addition, it provides an unhealthy environment that may compromise the health of individuals constantly exposed to formaldehyde. There are alternative techniques such as glycerination, cryodehydration, and corrosion, which reduce health risks caused by exposure to materials, provide an environment free of unpleasant odors and facilitate handling and storage of parts, when compared to formalization. This work aims to present alternative techniques for the conservation and maintenance of anatomical parts and their proper procedures, seeking to replace the use of formaldehyde the main form of conservation. The glycerination technique presents great efficiency in preserving the viscera's color and shape characteristics, in addition to being a low-cost technique and not presenting health risks, as well as the cryodehydration technique. The cryodehydration differs in relation to the tonality of the viscera; however, it demonstrates convenience in terms of their conservation, storage, and maintenance. On the other hand, the injection and corrosion of organs facilitate the visualization of the internal architecture of hollow organs, in addition to allowing the model of organ vascularization. However, it can be considered an expensive technique depending on the polymer used.

Seroprevalence of Leptospira spp. in horses from Rio Grande do Norte, Brazil / Soroprevalência de Leptospira spp. em equinos do Rio Grande do Norte, Brasil

This study aimed to determine the prevalence and risk factors associated with the presence of anti-Leptospira spp. antibodies in horses reared in the Eastern and Western Potiguar mesoregion, State of Rio Grande do Norte, northeastern Brazil. Seven hundred and eighty-five animals (785) were used from 90 properties from 2018 to 2019. The serological diagnosis was performed by the microscopic agglutination technique (MAT), using a collection of live antigens composed of twenty serovars belonging to sixteen serogroups. Variable data associated with risk factors were obtained from questionnaires carried out to herd owners and statistically analyzed. The absolute and relative frequencies were determined by descriptive analysis and risk factors by univariate analysis of the variables using the Pearson's chi-square test and Fisher's exact test, when necessary, and then assessed by Poison regression. The positivity frequency among animals was 97.2% (763), and from all properties, there was at least one seropositive animal. The main reactive serogroup was Icterohaemorrhagiae (72.88%), followed by reactive animals to Australis (14,94%), Sejroe (4.43%), Shermani (2.77%), Autumnalis and Pomona (1.29%). It was observed occurrences lower than 1% to serogroups Canicola, Ballum, Grippotyphosa and Hebdomadis, with titles ≤400 in 78,97% of cases. The significant occurrence of seropositive horses and the serogroup Icterohaemorrhagiae predominance highlights the importance of vaccination and hygiene in Potiguares herds facilities to prevent leptospirosis cases and the consequent elimination of the agent in the environment.

Este estudo objetivou determinar a prevalência e os fatores de risco associados à presença de anticorpos anti-Leptospira spp. em equinos criados na mesorregião Leste e Oeste Potiguar, estado do Rio Grande do Norte, Nordeste do Brasil. Foram utilizados 785 animais oriundos de noventa propriedades durante o período de 2018 e 2019. O diagnóstico sorológico foi realizado pela técnica de soroaglutinação microscópica (MAT) utilizando coleção de antígenos vivos composta por vinte sorovares, pertencentes a dezesseis sorogrupos. Os dados das variáveis associadas aos fatores de risco que podem predispor a presença de equinos soropositivos, foram obtidos a partir de questionários aplicados aos proprietários dos rebanhos e analisados estatisticamente. As frequências absolutas e relativas foram determinadas por análise descritiva e os fatores de risco por análise univariada das variáveis de interesse pelo Teste de Qui-quadrado de Pearson e Exato de Fisher, quando necessário, e em seguida submetidos à análise de regressão de Poison. A frequência de equinos soropositivos foi de 97,2% (763), sendo que em todas as propriedades houve pelo menos um animal com presença de anticorpos. O sorogrupo predominante foi o Icterohaemorrhagiae (72,88%), seguido do Australis (14,94%), Sejroe (4,43%), Shermani (2,77%), Autumnalis e Pomona (1,29%). Ocorrências menores que 1% foram observadas para os sorogrupos Canicola, Ballum, Grippotyphosa e Hebdomadis, com títulos ≤400 em 78,97% dos casos. Devido à alta ocorrência de equinos soropositivos e a predominância do sorogrupo Icterohaemorrhagiae, ressalta-se a importância da vacinação e da higiene das instalações nos rebanhos Potiguares na prevenção de casos de leptospirose e a consequente eliminação do agente no ambiente.

Seroprevalence and risk factors associated with seropositivity for equine encephalomyelitis virus in horses in Rio Grande do Norte, Brazil

The present objective was to investigate the presence of anti-equine viral encephalomyelitis (EVE) antibodies and the possible risk factors for its dissemination in horses raised in the East and West Potiguar mesoregions of the state of Rio Grande do Norte, Brazil. Serological diagnosis for neutralizing antibodies against Eastern (EEEV), Western (WEEV) and Venezuelan (VEEV). Equine viral encephalomyelitis was performed using a seroneutralization technique on 811 blood samples from horses from ninety properties and sixteen municipalities between July 2018 and February 2019. Factors associated with EVE were evaluated using an investigative epidemiological questionnaire, and the data were statistically analyzed using the Epi Info 3.5.2 software with a confidence level of 95%. The seroprevalence of anti-EVE antibodies was 14.2% (115), with 10.36% (84) for EEEV, 6.9% (56) for WEEV, and null for EVE. When analyzing risk factors, it can be concluded that horses raised in properties that do not clean installations and/or rent out their pasture are more likely to have anti-EVE antibodies. These results show evidence that horses raised in the East and West Potiguar mesoregions were exposed to EEEV and WEEV, thus reinforcing the importance of vaccination and serological survey of nonvaccinated horses as a means of monitoring the disease.

Is bluetongue virus a risk factor for reproductive failure in tropical hair sheep in Brazil?

Background: Bluetongue is a vector-borne viral disease transmitted by midges from the genus Culicoides. The disease caninfect most of the ruminant and camelid species, but the severe disease is most often seen in european wool and muttonsheep breeds. In this sense, there is a gap in the knowledge on BTV infection in hair sheep breeds from tropical zones.Thus, this study aimed at establishing whether exposure to BTV is a risk factor for reproductive failure in Santa Inês ewes,a hair sheep breed, reared under tropical conditions in Brazil.Materials, Methods & Results: A retrospective cross-sectional study was carried out in sheep farms in São Paulo state,Brazil, after the rainy season. Serum samples from 110 Santa Inês ewes with a history of reproductive disorders, in the last6 months, which were included: abortion, premature birth, stillbirth, retention of placenta, infertility, estrus repetition, fetalmalformation, weak lamb birth and neonatal death were collected. The presence of antibodies against BTV was assessedby agar gel immunodiffusion method (AGID). Serology to the infectious agents Brucela ovis, Lepstopira spp., Toxoplasmagondii, Neospora caninum and Campylobacter sp. were also assessed. Bivariate associations between the outcome andindividual explanatory variables were assessed using the Fishers exact test. Abortion was the most common reproductive disorder (53%; 74/139) observed, followed by estrus repetition (12%; 17/139) and infertility (11%; 15/139). Otherdisorders related to the conceptus totaled nearly one fourth of the reported disorders. A total of 20% (22/110) of the eweswere seropositive to BTV. A higher frequency of BTV seropositive than BTV seronegative ewes with a history of abortionwas found. Also, abortion with seroreactivity to BTV was tested for prevalence ratio that showed 1.38 [95% CI 1.10-1.74;P = 0.030]. With regards to the abortion involvement of other infectious diseases associated with the seropositive ewes to...(AU)

Miliary tuberculosis in catlle in Sergipe State, Brazil / Tuberculose miliar em bovino no estado de Sergipe

O objetivo deste trabalho é relatar o primeiro caso de tuberculose miliar em bovino no estado de Sergipe, seus achados clínicos e patológicos. Um bovino, fêmea, com histórico de que há dez dias apresentava emagrecimento progressivo e no oitavo dia de evolução clínica começou a apresentar incoordenação e anorexia. No exame clínico do sistema nervoso foi observado desvio lateral da cabeça, déficit proprioceptivo com dismetria, ataxia, redução do tônus lingual, flacidez de mandíbula, ausência do reflexo de deglutição e compressão da cabeça contra objeto. Macroscopicamente foram observados múltiplos nódulos nos pulmões, diafragma, linfonodos mediastínicos, glândula mamária, encéfalo e medula espinhal, amarelados, de tamanhos variados e consistência firme que, ao corte, apresentavam conteúdo amarelado pastoso com aspecto arenoso. O coração continha abundante líquido serosanguinolento no saco pericárdico, com presença de fibrina livre no líquido e aderida ao epicárdio. Histologicamente, as lesões nodulares caracterizavam-se pela formação de lesão granulomatosa caracterizada por uma área central de necrose, rodeada por macrófagos epitelióides, poucos linfócitos e abundantes células gigantes multinucleadas do tipo Langhans, exibindo áreas multifocais de calcificação caracterizando o quadro de tuberculose miliar, confirmado com a coloração de Ziehl Neelsen. A tuberculose miliar deve ser considerada no diagnóstico diferencial de enfermidades que acometem o sistema nervoso em bovinos oriundos de rebanhos com elevados índices de animais positivos para tuberculose, reforçando a importância do inquérito a respeito da prevalência desta enfermidade.(AU)

The objective of this work is to report the first case of miliary tuberculosis in cattle in the state of Sergipe, Brazil, with its clinical and pathological findings. A female bovine with a ten-day history had progressive weight loss and on the eighth day of clinical evolution showed incoordination and anorexia. The clinical examination of the nervous system indicated lateral deviation of the head, proprioceptive deficit with dysmetria, ataxia, reduced lingual tone, flaccidity of the jaw, absence of the swallowing reflex and compression of the head against an object. After euthanasia, multiple nodules were observed in the lungs, diaphragm, mediastinal lymph nodes, mammary glands, brain and spinal cord. Yellowish of varying sizes and firm consistency were observed at the macroscopic level and when cut, had a pasty yellowish content with a sandy aspect. The heart contained abundant serosanguinous fluid in the pericardial sac, with the presence of free fibrin in the liquid and adhered to the epicardium. In the histological analysis, the nodular lesions were characterized by the formation of granulomatous lesions with a distinctive central area of necrosis, surrounded by epithelioid macrophages, few lymphocytes and abundant giant multinucleated cells of the Langhans type, showing multifocal areas of calcification characterizing miliary tuberculosis, confirmed with the Ziehl Neelsen stain. Miliary tuberculosis must be considered in the differential diagnosis of diseases that affect the nervous system in cattle from herds with high levels of animals positive for tuberculosis, reinforcing the importance of the investigation regarding the prevalence of this disease.(AU)

Fatores associados à infecção pelo vírus da estomatite vesicular em equídeos no estado do Rio Grande do Norte, Brasil / Factors associated with infection by the vesicular stomatitis virus in equines in the state of Rio Grande do Norte, Brazil

Objetivou-se investigar a presença do Vírus da Estomatite Vesicular (VEV) e seus fatores de risco para ocorrência e disseminação da enfermidade em equídeos das mesorregiões Leste e Oeste Potiguar do estado do Rio Grande do Norte, Brasil. Foram analisadas pela técnica de virusneutralização, 809 amostras sanguíneas de equídeos provenientes de noventa propriedades de dezesseis municípios Potiguares durante os meses de julho de 2018 a fevereiro de 2019. Os fatores de riscos associados ao VEV foram avaliados por meio de questionário epidemiológico e os dados submetidos a análise estatística no programa IBM SPSS Statistics versão 21.0 com nível de confiança de 95%. Posteriormente, todas as variáveis estatisticamente significantes foram submetidas a análise de regressão de Poisson. A soroprevalência de anticorpos anti-VEV foi 24,6% (199/809), sendo 3,2% (13/402) de soropositivos na mesorregião Leste e 45,7% (186/407) na do Oeste Potiguar. Com relação aos sorotipos, observou-se uma prevalência de 3,8% (31/809) e 24,5% (198/809) para Indiana 2 e 3 respectivamente, com 15,1% (30/198) de coinfecção. Equídeos criados na mesorregião Oeste, em propriedades que não realizam quarentena e onde os animais enfermos são mantidos no rebanho, foram consideradas fatores predisponentes a infecção pelo VEV. Esses resultados demonstram a circulação do VEV em equídeos no Rio Grande do Norte, com destaque ao Oeste Potiguar, e sendo necessário a aplicação de medidas sanitárias que impeçam introdução e disseminação do vírus ente as espécies susceptíveis, principalmente em condições climáticas favoráveis para a sua manutenção, no ambiente de criação e pastagens.

This study aimed to investigate the presence of Vesicular stomatitis virus (VSV) and risk factors for its occurrence and dissemination in equines from the Eastern and Western mesoregions of the state of Rio Grande do Norte, Brazil. Blood samples were analyzed, by Serum Virus Neutralization Assay, from 809 animals belonging to 90 properties distributed in sixteen municipalities from July 2018 to February 2019. Risk factors were assessed using an epidemiological questionnaire. Data were submitted to statistical analysis using the software IBM SPSS Statistics, version 21.0 with a 95% confidence level. Also, all statistically significant variables were subjected to Poisson regression analysis. The occurrence of anti-VSV antibodies was 24.6% (199/809) with 3.2% (13/402) and 45.7% (186/407) of seropositivity in the Western and Eastern mesoregion, respectively. Regarding serotypes, there were an occurrence of 3.8% (31/809) and 24.5% (198/809) for Indiana 2 and 3, respectively, and 15.1% (30/198) of co-infection for both. Equines kept of the Western mesoregion, on properties that do not quarantine, and where sick animals are kept in the herd, were considered risk factors for LVV infection. These results demonstrate the presence of VSV in equines in Rio Grande do Norte, with emphasis on Oeste Potiguar, and that sanitary measures must be adopted to prevent the introduction and viral spreading among susceptible species, especially due to favorable climatic conditions for the maintenance of VSV in the breeding and pasture environment.

A soroprevalência de anticorpos anti-VEV foi 24,6% (199/809), sendo 3,2% (13/402) de soropositivos na mesorregião Leste e 45,7% (186/407) na do Oeste Potiguar. Com relação aos sorotipos, observou-se uma prevalência de 3,8% (31/809) e 24,5% (198/809) para Indiana 2 e 3 respectivamente, com 15,1% (30/198) de coinfecção. Equídeos criados na mesorregião Oeste, em propriedades que não realizam quarentena e onde os animais enfermos são mantidos no rebanho, foram consideradas fatores predisponentes a infecção pelo VEV. Esses resultados demonstram a circulação do VEV em equídeos no Rio Grande do Norte, com destaque ao Oeste Potiguar, e sendo necessário a aplicação de medidas sanitárias que impeçam introdução e disseminação do vírus ente as espécies susceptíveis, principalmente em condições climáticas favoráveis para a sua manutenção, no ambiente de criação e pastagens.(AU)

This study aimed to investigate the presence of Vesicular stomatitis virus (VSV) and risk factors for its occurrence and dissemination in equines from the Eastern and Western mesoregions of the state of Rio Grande do Norte, Brazil. Blood samples were analyzed, by Serum Virus Neutralization Assay, from 809 animals belonging to 90 properties distributed in sixteen municipalities from July 2018 to February 2019. Risk factors were assessed using an epidemiological questionnaire. Data were submitted to statistical analysis using the software IBM SPSS Statistics, version 21.0 with a 95% confidence level. Also, all statistically significant variables were subjected to Poisson regression analysis. The occurrence of anti-VSV antibodies was 24.6% (199/809) with 3.2% (13/402) and 45.7% (186/407) of seropositivity in the Western and Eastern mesoregion, respectively. Regarding serotypes, there were an occurrence of 3.8% (31/809) and 24.5% (198/809) for Indiana 2 and 3, respectively, and 15.1% (30/198) of co-infection for both. Equines kept of the Western mesoregion, on properties that do not quarantine, and where sick animals are kept in the herd, were considered risk factors for LVV infection. These results demonstrate the presence of VSV in equines in Rio Grande do Norte, with emphasis on Oeste Potiguar, and that sanitary measures must be adopted to prevent the introduction and viral spreading among susceptible species, especially due to favorable climatic conditions for the maintenance of VSV in the breeding and pasture environment.(AU)

Characterization of goat and sheep production in the state of Sergipe, Northeast of Brazil / Caracterização do sistema de produção de caprinos e ovinos no estado de Sergipe, Nordeste do Brasil

Characterization of the profile of goat and sheep production in Sergipe enables better understanding of the main barriers linked to low productivity, generating important information for the development of this sector. The objective was to identify and characterize the production of goats and sheep in Sergipe. From 2011 to 2014, 41 goat properties and 60 sheep properties were analyzed, located in 25 municipalities in the three mesoregions of the State (Leste, Agreste, and Sertão). The information was obtained through application of a structured questionnaire to the farmers addressing topics such as: characterization of the property, herd, facilities, sanitary, nutritional, and reproductive management, and socioeconomic aspects of the farmer.  The results demonstrated that 58.5% (24/41) of goat farms had an area less than 30 hectares (ha), reared predominantly mixed breed animals (SRD), with low use of technologies, aiming at family consumption, and complementing income through local marketing. On the sheep properties, 58.3% (35/60) were over 100 ha and used for the production of Santa Inês sheep and crossbreeds together with cattle. Significant flaws were also observed in feed, sanitary, and reproductive management, emphasizing the non-use of preserved foods and forages typical of the region, factors that contribute to the low level of productivity and ustainability of production in a viable and homogeneous manner. The findings led to the conclusion that more organized production is necessary, mainly through investment in technologies and qualified and continuous rural extension, aiming at improving the production, productivity, income, and quality of life of the breeders.(AU)

A caracterização do perfil das criações possibilita um maior entendimento dos principais entraves ligados a baixa produtividade e auxilia na disponibilização de dados importantes para a busca de soluções para crescimento da ovinocaprinocultura. O presente trabalho teve como objetivo caracterizar o sistema de produção de caprinos e ovinos no estado de Sergipe. Foram visitadas entre os anos de 2011 e 2014, 41 e 60 propriedades de caprinos e ovinos, respectivamente, localizadas em 25 municípios distribuídos nas três mesorregiões do Estado (Leste, Agreste e Sertão). O levantamento dos dados ocorreu pela aplicação de questionário junto aos proprietários, com temas referentes às características do rebanho, instalações, manejo sanitário, nutricional e reprodutivo eperfil do criador. A caprinocultura foi caracterizada como atividade complementar da renda de pequenos produtores rurais, com a maioria do rebanho representado por animais de padrão racial não definido e pela raça Saanen. A atividade é voltada ao consumo familiar com baixo uso tecnológico e produção leiteira para atendimento do comércio local. Enquanto que na ovinocultura, os rebanhos são compostos por animais puros e mestiços da raça Santa Inês mantidos em grandes áreas de terra devido a sua criação consorciada com bovinos. As falhas de manejo observadas nos rebanhos caprinos e ovinos comprometem a viabilidade do sistema de produção, contribuindo com maiores desafios para ovinocaprinocultura sergipana em atender a demanda do mercado consumidor do Estado(AU)

Dilatação e torção de ceco associada à obstrução por fitobezoar em bezerra / Cecal dilatation and torsion associated with phytobezoar obstruction in a heifer

Background: Dilatation of the cecum associated with intestinal torsion is a fermentative digestive disease that has a lowoccurrence in veterinary medicine, particularly in large animal practice. This condition is most prevalent in dairy cattle.The etiology of this digestive system disorder is related to changes in nutritional management. As it is an uncommoncondition that is frequently observed in the practice of veterinary medicine, the objective of this report was to describe acase of dilatation and torsion of the cecum associated with phytobezoar obstruction in a heifer that was examined at theVeterinary Hospital of the Federal Rural University of Pernambuco (HOVET-UFRPE), Recife, Brazil.Case: A 55-day-old heifer, with a history of abdominal distension associated with difficulty feeding and neurological signsof hind limb paresis, intentional head tremors, and prostration, was examined at the HOVET-UFRPE large animal clinic.A clinical examination demonstrated the presence of enophthalmos, abdominal distension, pale coloration of the ocularmucous membranes, and a moderate level of dehydration (3%). The dehydration was treated through the administrationof 1.150 L of saline solution along with 6 mL of Bionew (Vetnil®), 15 mL of calcium solution, and 5 mL of 50% glucose.Subsequently, the animal underwent intestinal washing through the insertion of an oral probe, which resulted in the expulsion of putrid content. Afterward, the animals blood was collected and sent to the Clinical Pathology Laboratory of theDepartment of Veterinary Medicine at HOVET-UFRPE for a complete blood count...(AU)

Hypertrophic osteoarthropathy in a sheep / Osteoartropatia hipertrófica em um ovino

This research described the radiological, clinical and pathological aspects of hypertrophic osteoarthropathy in a seven-year-old Santa Inês ram. The main clinical features were lameness of the thoracic and pelvic limbs, rigid, cracking and enlarged of the humeroradial, humeroulnar and tibiofemoral joints, cervical spine stiffness, and severe lordosis of the thoracolumbar vertebrae. Dyspnea, nasal discharge and abdominal breathing were also observed. On radiographic examination of the thoracic and pelvic limbs, osteoarthrosis with the formation of osteophyte bridging, intra-articular calcification and periosteum reaction were observed. At necropsy were reported bilateral osteophytosis in the humeroradial, humeroulnar, tibiofemoral and interphalangeal joints, and fusion of the bodies of thoracic vertebrae T5-13 T6 and T12-T13. Microscopically, extensive areas of fibrosis were observed in the lungs and the affected joints were thickened by well demarcated and perpendicular orientated woven and trabecular bone proliferation in the epiphysis. The periosteum was also expanded by fibrous connective tissue that extended into and between the new proliferated bone. Based on these findings, hypertrophic osteoarthropathy, which is an unusual condition in sheep, was diagnosed.(AU)

Este trabalho descreve os aspectos radiográficos e clínico-patológicos de um caso de osteoartropatia hipertrófica em um ovino, macho, de sete anos de idade, da raça Santa Inês. Os principais sinais clínicos consistiram em claudicação dos membros torácicos e pélvicos, rigidez, crepitação e aumento das articulações úmero-radio-ulnar e femoro-tibio-patelar, rigidez na coluna cervical e severa lordose das vértebras toracolombares. Dispneia, secreção nasal e respiração abdominal também foram observadas. No exame radiográfico dos membros torácicos e pélvicos, foram observadas osteoartrose com formação de osteófitos em ponte, calcificação intra-articular e reação do periósteo. À necropsia notou-se osteofitose bilateral nas articulações umerorradioulnar, femorotibiopatelar e interfalangiana e fusão dos corpos das vértebras torácicas T5-T6 e T12-T13. Microscopicamente, havia áreas extensivas de fibrose pulmonar e as articulações afetadas encontravam-se expandidas pela proliferação de tecido ósseo recém-formado e trabecular, bem demarcado na epífise. O periósteo também estava expandido por tecido conjuntivo fibroso que se estendia dentro e entre o novo osso proliferado. Com base nestes achados, osteoartropatia hipertrófica, que é uma condição inusual em ovinos, foi diagnosticada.(AU)
