RESUMO.-Este trabalho teve por objetivo realizar um levantamento sobre as plantas tóxicas para ruminantes e equídeos na Mesorregião Norte do Piauí. Foram feitas 71 entrevistas a médicos veterinários, engenheiros agrôno-mos, técnicos agrícolas e produtores de 16 municípios, entrevistando pelo menos quatro pessoas por município. As plantas comprovadamente tóxicas que foram apontadas com maior frequência na região estudada foram Ipomoea asarifolia, que causa intoxicações em pequenos ruminantes em todas as áreas visitadas. Stryphnodendron coriaceum pelas mortes que ocasiona é, aparentemente, a planta que causa maiores perdas econômicas na me- The objective of this study was to survey toxic plants for ruminants and equidae in northern Piauí. Seventy one persons were interviewed, including farmers, veterinary practitioners, agronomists, and agrarian technicians from 16 municipalities, performing at least four interviews in each municipality. The most common plant mentioned as a cause of poisoning was Ipomoea asarifolia, which is a well known cause of tremogenic disease in ruminants. Stryphnodendron coriaceum which causes digestive signs was referred as a common cause of death, and is probably the plant that causes most cattle deaths in the region. Enterolobium contortisiliquum was also mentioned as a frequent cause of digestive signs, abortion and photosensitization in cattle. Outbreaks of nephrosis caused by Thiloa glaucocarpa are frequent at the beginning of the raining season. Poisoning by the cyanogenic plants Manihot spp. e Piptadenia macrocarpa are a cause of peracute deaths. Other plants mentioned as toxic were Buchenavia tomentosa, Caesalpinia sp., Brunfelsia sp., Luetzelburgia sp., Hybantus ipecaconha, Phisalys angulata, and Spondias luta. Farmers report that goats are poisoned by the ingestion of the pods of Luetzelburgia sp., which causes digestive signs and death. The ingestion of the fruits of Buchenavia tomentosa is associated with digestive signs and and abortion in ruminants. Brunfelsia sp. is mentioned as a cause of nervous signs at the start of the raining season and donkeys are apparently more affected. The consumption of the fruits of Spondias luta are associated with diarrhea in goats. Recent unpublished experiments demonstrated the toxicity of Brunfelsia sp. as a cause of nervous signs and of Luetzelburgia sp. as a cause of digestive signs in goats. Experiments with other plants are necessary to confirm their toxicity.

O conhecimento das principais causas de óbito em cães e gatos fornece subsídios para o monitoramento, planejamento e avaliação de medidas que visam reduzir o percentual de óbito desses animais em uma dada localidade. O presente trabalho compilou os diagnósticos post-mortem de cães e gatos necropsiados no Laboratório de Patologia Animal – da Universidade Federal do Piauí (UFPI), Estado do Piauí, Brasil, no período de agosto de 2009 a agosto de 2014, estabelecendo a frequência das doenças que culminaram com o óbito dos animais. Nesse período foram necropsiados 361 cães e 86 gatos. Dos cães, 56,7% eram machos e 43,3% fêmeas. Em relação à idade no momento do óbito, 29,4% tinham menos de um ano; 27,7% entre 1,1 a 5 anos; 23,3% de 5,1 a 10 anos e 9,1% acima de 10,1 anos. Em relação aos felinos, 61,6% eram machos e 38,4% eram fêmeas, dos quais 29,1% tinham menos de um ano; 39,5% de 1,1 a 5 anos; 18,6% de 5,1 a 10 anos e 2,3% acima de 10,1 anos. Nos cães as principais causas de óbito foram distúrbios infecciosos (23,8%), doenças degenerativas (14,4%), distúrbios circulatórios (10,2%) e neoplasias 8,6%. Em gatos, os distúrbios infecciosos (18,6%), urinários (15,1%), traumáticos (8,1%) e neoplasias (8,1%) foram as principais causas de morte. Conclui-se que a principal causa de morte, tanto em cães quanto gatos, diagnosticada no setor de Patologia Animal – UFPI foram as doenças infecciosas, estes resultados contribuem para que o clínico dedique maior atenção a essas enfermidades, visando adoção de medidas profiláticas que reduzirão a sua ocorrência nos animais de companhia da região estudada.

Pesq. Vet. Bras. 33(9) The goal of this study was to characterize the epidemiological situation and the factors involved in the prevalence of babesiosis and anaplasmosis in cattle in the dairy basin of Parnaíba, Piauí, Brazil. The study was conducted in 22 farms, and collected blood samples from 202 cattle to study serological, molecular and determination of the packed cell volume (PCV). On the farms were applied surveys involving epidemiological aspects. Seroprevalence rates were: Babesia bigemina 52.5%, B. bovis 68.8%, and Anaplasma marginale 89.1%. Of the samples analyzed, 73.3% were reactive for Babesia spp. and A. marginale, showing co-infection. In PCR, B. bigemina and B. bovis were positive in 52.0% and 33.2% respectively, and A. marginale in 76.2%. Of these, 51.5% amplified DNA of Babesia spp. and A. marginale. The semi-intensive management predominated in 68.0% of the farms studied. The clinical history of babesiosis and anaplasmosis, was reported from 73% of the farms. There was no significant difference (p>0.05) between age groups and for the PCV of positive compared with negative animals. The study indicates that in this region is enzootic instability for babesiosis and enzootic stability for anaplasmosis, reinforcing the fact that in Brazil there are areas of enzootic instability, even in tropical regions of the country. The PCR technique was a valuable tool for the diagnosis of these diseases and may be used to characterize a geographic region. ões tropicais do país. A técnica de PCR demonstrou ser uma ferramenta valiosa para o diagnóstico destas doenças e pode ser utilizada para caracterizar uma região geográfica.

ResumoAs hérnias umbilicais surgem como massas arredondadas e macias localizadas na cicatriz umbilical. Uma hérnia umbilical surge porque a linha alba deixou de se fechar em volta do pedículo do cordão umbilical e em muitos casos isto é predisposto pela infecção moderada do resíduo umbilical. Muitas das hérnias umbilicais são hereditárias, e provavelmente são resultantes de caráter

A 21-yr-old female jaguar (Panthera onca) died in a zoo in Teresina, Piaui, Brazil, following a history of abdominal distension, ascites, anorexia, and dyspnea. At necropsy, a dark red, watery, blood-tinged serous fluid was present in the abdominal cavity. The peritoneum was thick with firm, yellow, villous projections. Histologically, the tumors were composed of a biphasic population of cells, which reacted to anti-cytokeratin and anti-vimentin antibodies, consistent with a biphasic benign mesothelioma of peritoneal origin. This is the first reported case of mesothelioma in a captive jaguar.
