In addition to listeriosis which is relatively common in ruminants, there are three other uncommon suppurative intracranial processes (SIP) identifiable in adult ungulates as brain abscess, basilar empyema and suppurative meningitis. The present paper reports the epidemiological, clinical, laboratorial, pathological and microbiological findings of 15 domestic ruminants with SIP. A total of 15 animals were selected (eight sheep, four cattle and three goats); with the definitive diagnoses of basilar empyema (n=3), brain abscess (n=1), listeriosis (n=5) and suppurative meningitis (n=6). Hematology revealed leukocytosis with inversion of the lymphocyte/ neutrophil ratio in 4 cases. In the majority of animals, cerebrospinal fluid (CSF) presented light yellow coloration and cloudy aspect due to neutrophilic pleocytosis (15 -997 leukocytes/µL). Microbiological culture of CSF or central nervous system (CNS) fragments resulted on isolation of Trueperella (Arcanobacterium) pyogenes, Listeria monocytogenes, Escherichia coli and Stenotrophomonas sp. In a goat with thalamic abscess, microbiological assay was not performed, but Gram positive bacilli type bacteria were observed in histology. The diagnosis of these outbreaks was based on the association of epidemiological, clinical, pathological and bacteriological findings; reiterating that the infectious component remains an important cause of CNS disease in domestic ruminants and also shows the need for dissemination of information about the most effective preventive measures for the ranchers. teriológicos; reiterando que o componente infeccioso continua sendo uma causa importante de doença do SNC em ruminantes domésticos e também mostra a necessidade de disseminação da informação sobre as medidas preventivas mais eficazes para os criadores.TERMOS DE INDEXAÇÃO: Abscesso cerebral, animais de produção, empiema basilar, listeriose, meningite supurativa.
The present study aimed to report the occurrence as well as the clinical, laboratorial, pathological and mycological findings of three outbreaks of rhinocerebral and rhinopharyngeal conidiobolomycosis in sheep from
Objetivou-se com este trabalho estudar o perfil hematológico de caprinos (Capra hircus) da raça Canindé, criados no Estado do Rio Grande do Norte, como também a busca de valores de referência que se adequem à nossa região. Foram coletadas amostras sanguíneas de 58 animais clinicamente sadios, distribuídos em 4 grupos (machos acima de 5 meses, fêmeas gestantes, fêmeas não gestantes e filhotes até 4 meses de idade). A partir de única amostra de sangue de cada animal foram realizados o eritrograma (contagem de hemácias, hematócrito, hemoglobina, volume corpuscular médio e concentração de hemoglobina corpuscular média) e o leucograma (contagem total e diferencial de leucócitos). Os dados obtidos foram avaliados por meio do teste de Tukey para variáveis paramétricas e Kruskal-Wallis seguido pelo teste de Dunn para não paramétricos em nível de significância de (p<0.05). Os resultados apontam para existência de maiores quantidades de He nos machos adultos e fêmeas não gestantes, diferente do que ocorre com o VCM; já com relação ao leucograma temos que os eosinófilos mostram-se mais elevados nas fêmeas adultas e os monócitos se elevam quando na presença da gestação. Os valores deste trabalho podem servir de referência para raça Canindé, tornando possível futuras interpretações para os parâmetros verificados, além de subsidiar novos estudos em animais hígidos ou doentes. Mostra a necessidade de pesquisas que evidenciem as condições semiáridas de manejo e alimentação, bem como a avaliação dos fatores de variação, sobre constituintes do sangue, que levem em conta o sexo, a idade e estado fisiológico dos animais.
Cottonseed cake contains gossypol, a potentially toxic compound that, when consumed by sheep, can affect reproduction, the immune system, and the liver. Changes in hematologic and serum biochemical parameters were monitored for 63 days in 12 Santa Inês ewes, six of which received ration containing 400 g kg(-1) of cottonseed cake. Blood samples were collected at the start of the experiment and weekly thereafter for hematologic assessment and determination of serum urea, creatinine, total protein, and albumin concentrations and for measurement of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and γ-glutamyl transferase activities. No clinical signs of toxicity were observed. Evaluation of the erythron showed that sheep consuming cottonseed cake had an increased packed cell volume (p < 0.05) and increased erythrocyte counts and hemoglobin concentrations (p < 0.05) in the leukogram and serum biochemistry panel. In conclusion, consumption of 400 g kg(-1) cottonseed cake by sheep for 63 days may induce changes in the erythron but no consistent changes in serum biochemical parameters, indicating no damage to the liver or kidneys.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
