Resumo

Background: South American rattlesnake (Crotalus durissus spp.) envenomation is rarely reported in small animals andlivestock in Brazil. Minor swelling at the snakebite site, skeletal muscle, and renal damage, and severe neurological signscharacterize the crotalic envenomation. This case report aims to present epidemiological, clinical, and pathological dataof two cases of Crotalus durissus spp envenomation in dogs in the Northeast of Brazil.Cases: Envenomation by Crotalus durissus spp. was recorded in two dogs in Patos, State of Paraíba, Brazil. In Case 1,the dog presented flaccid paralysis, hyporeflexia, a deficit of cranial nerves, epistaxis, and gingival hemorrhages. Laboratory assay showed proteinuria, myoglobinuria, regenerative thrombocytopenia, and increased serum activities of creatinekinase (CK), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP). The dogwas medicated with crotalic antivenom and wholly recovered from local and systemic clinical signs. In Case 2, the dogdied and was detected fang marks at the ventral region of the left mandible (two small parallel perforations spaced 2.0 cmapart) at the snakebite site. Cyanosis of the oral cavity, congestion, and hemorrhages in several organs were observed atnecropsy. Tubular nephrosis, muscular necrosis, hepatocytes swelling were observed. The owners witnessed snakebites,and the rattlesnakes (Crotalus durissus spp.) identified by the rattle at the end portion of the tail in both cases.Discussion: Natural South American rattlesnake envenomation presents complex clinical signs that makes diagnosis achallenge for veterinary practitioners. The criteria for the correct diagnosis and observed in the two dogs include witness ofthe snakebite, identification of the snake, detection of fang marks, clinical-pathological findings, and therapeutic responseto treatment with specific anti-venom....

Resumo

Amorimia septentrionalis is a sodium monofluoroacetate (MFA) - containing plant that causes sudden death in ruminants. The aim of this study was to determine whether the resistance to A. septentrionalis poisoning in goats conferred by the intra-ruminal inoculation with the MFA-degrading bacteria Ancylobacter dichloromethanicus and Pigmentiphaga kullae can be transferred to susceptible goats by the transfaunation of rumen content. Two groups of 8 goats and 2 goats resistant to A. septentrionalis poisoning were used. Goats in Group 1 received four daily doses of 160ml of rumen content from resistant goats and subsequently ingested 8 daily doses of 5g kg-1 of A. septentrionalis. Goats from Group 2 (control) received only the plant. In Group 1, only 2 goats showed mild tachycardia and mild jugular vein engorgement on the 4th and 5th day, but they subsequently returned to normal, even with the continuation of plant administration. All control goats showed severe signs of intoxication and the plant administration was suspended between the 3rd and 7th day. So, the transfer of ruminal fluid from goats previously inoculated with MFA-degrading bacteria induces resistance to poisoning by A. septentrionalis in susceptible goats.(AU)


Amorimia septentrionalis é uma planta que contém monofluoracetato de sódio (MFA) e causa morte súbita em ruminantes. O objetivo deste trabalho foi determinar se a resistência à intoxicação conferida por A. septentrionalis em caprinos inoculados com as bactérias degradadoras de MFA, Ancylobacter dichloromethanicus e Pigmentiphaga kullae, pode ser transferida, por transfaunação ruminal, para outros caprinos suscetíveis. Para tanto, foram utilizados dois caprinos previamente inoculados com bactérias degradadoras de MFA e dois grupos de oito caprinos para o experimento de transfaunação, denominados Grupo 1 e Grupo 2. Os caprinos do Grupo 1 receberam 4 doses diárias de 160ml de conteúdo ruminal dos caprinos resistentes e, posteriormente, ingeriram 8 doses diárias de 5g kg-1 da planta. Os caprinos do Grupo 2 (controle) receberam apenas a planta. Dos caprinos do Grupo 1, apenas 2 animais apresentaram discreta taquicardia e leve ingurgitamento da veia jugular no 4o e 5o dia do experimento, no entanto, estes voltaram ao normal, mesmo com a continuação da administração da planta. Todos os animais do grupo controle apresentaram sinais graves de intoxicação e a administração da planta foi suspensa entre e o 3o e o 7o dia. Conclui-se que a transfaunação de líquido ruminal de caprinos previamente inoculados com bactérias degradadoras de MFA induz resistência à intoxicação por A. septentrionalis em outros caprinos susceptíveis.(AU)
