#1 - Spontaneous poisoning by Ricinus communis leaves (Euphorbiaceae) in goats

Abstract in English:

The aim of this study was to report the clinical and pathological aspects of an outbreak of poisoning by the ingestion of Ricinus communis leaves in a herd of goats at Pernambuco, northeastern Brazil. Within 3-5 hours after ingesting the sprouts and young shrubs of the plant, twenty Toggenburg female goats and two adults crossbred wethers presented acute neurological clinical signs, which were initially characterized by decreased locomotor activity that later evolved to severe ataxia, depression, incoordination and staggering gait. Four goat that died spontaneously were necropsied. Gross lesions were unspecific and consisted in focal areas of lungs edema, petechial hemorrhages in the epicardium and congestion and enlargement of liver. The contents of the rumen, reticulum and omasum were dry and contained leaves of the plant. Histologically there were no lesions in the CNS. In the liver, the main lesion consisted in cytoplasmic vacuolization and necrosis of hepatocytes. Eighteen goats recovered after a supportive therapy with activated charcoal, glycated isotonic solution, dexamethasone and vitamin B12. There is no specific therapy for poisoning by R. communis, however supportive and symptomatic treatments are recommended and should be based on the clinical signs.

Abstract in Portuguese:

O objetivo deste estudo foi relatar os aspectos clínicos e patológicos de um surto de intoxicação pelas folhas de Ricinus communis em um rebanho de caprinos em Pernambuco, Nordeste do Brasil. Três a cinco horas após a ingestão dos brotos e arbustos jovens da planta, vinte cabras da raça Toggenburg e dois machos mestiços apresentaram quadro clínico neurológico agudo caracterizado principalmente pela diminuição da atividade locomotora, grave ataxia, depressão, incoordenação e marcha cambaleante. Quatro caprinos morreram espontaneamente e foram necropsiados. Macroscopicamente, as lesões eram inespecíficas e consistiam em áreas focais de edema pulmonar, hemorragias petequiais epicárdicas e aumento do volume e congestão do fígado. Os conteúdos do rumem, retículo e omaso eram ressecados e continham folhas da planta. Histologicamente, não foram observadas lesões no SNC. No fígado, havia vacuolização citoplasmática e necrose de hepatócitos. Dezoito caprinos se recuperaram após receberem terapia de suporte com carvão ativado, soro glicosado, dexametasona e vitamina B12. Não existe terapêutica especifica para a intoxicação pelas folhas de R. Communis. Os tratamentos sintomáticos e de suporte são recomendados e devem basear-se nos sinais clínicos.

E-mail: davidbarcellos@terra.com.br The occurrence and bacteriology of purulent otitis in groups of pigs affected by three different clinical conditions are described: postweaning multisystemic wasting syndrome (PMWS), depressed growth (attrition) and normal growth (control). A total of 385 animals, 60-130 days of age, were examined. Diagnosis of PMWS was confirmed by the presence of clinical signs and pathological findings compatible with the disease, and through detection of viral antigens in tissues by immunohistochemistry. From 242 pigs with PMWS, 57 (23.5%) showed purulent lesions in the middle ear. Among 119 pigs with attrition, only 1 (0.7%) presented the lesion. In 24 control pigs, middle ear lesions were not detected. The most frequently isolated agents from the lesions were Arcanobacterium pyogenes (43%), á–hemolytic Streptococci (37.2%) and Pasteurella multocida (27.9 %) out of 86 materials. The frequent occurrence of purulent lesions in the middle ear of PMWS affected pigs suggests that PCV2 infection may increase the susceptibility to bacterial otitis. The low occurrence of this disease in piglets with attrition suggests that otitis does not represent a significant cause for depressed growth in pigs from growing and finishing age. The isolation of A. pyogenes, á-hemolytic Streptococci and P. multocida from most of the lesions emphasizes the importance of these organisms as causal agents of otitis media in swine.
