| Toxigenic types of Clostridium perfringens are significant causative agents of enteric disease in domestic animals, although type E is presumably rare, appearing as an uncommon cause of enterotoxemia of lambs, calves and rabbits. We report herein the typing of 23 C. perfringens strains, by the polymerase chain reaction (PCR) technique, isolated from small intestine samples of bovines that have died suddenly, after manifesting or not enteric or neurological disorders. Two strains (8.7%) were identified as type E, two (8.7%) as type D and the remainder as type A (82.6%). Commercial toxoids available in Brazil have no label claims for efficacy against type E-associated enteritis; however, the present study shows the occurrence of this infection. Furthermore,... |

| The aim of this study was to report a case of clostridial myocarditis in a bovine in Brazil with emphasis on the pathological findings, isolation and molecular identification associated with the in situ localization of C. chauvoei. The animal, a male Brangus bull with nine months of age, was found dead without prior clinical signs. Multifocal and coalescent areas of necrosis were observed in the myocardium. Rod cells in the cardiac muscle fibers were positive immunostaining for C. chauvoei, while this bacterium was also isolated and identified by polymerase chain reaction (PCR). |

| ABSTRACT: Blackleg is an endogenous acute infection that principally affects cattle, whose etiologic agent is the anaerobic bacterium Clostridium chauvoei. In recent years, the major virulence factors of C. chauvoei have been discovered and described. However, the pathogenesis of blackleg in cattle, and in particular, the movement of the pathogen from the point of entry to the affected tissues is not yet fully elucidated. Disease control is based on appropriate management and vaccination. This review summarizes the latest research findings that contribute toward the understanding of the disease in cattle, provide a foundation to preventive strategies, and identify future research needs. |

| ABSTRACT: Amorimiapubiflora (Malpighiaceae), which contains sodium monofluoroacetate (MFA) is the main cause of "sudden death" in cattle in the Brazilian state of Mato Grosso. This research investigated the induction of resistance to the poisoning in sheep by the continuous administration of non-toxic doses of the plant and also the possibility to transfer this resistance to other sheep by the transfaunation of ruminal fluid. For this a group of four sheep (G1) received daily doses of 0.5g kg-1 for 20 days and after an interval of 15 days were challenged with three daily doses of 1g kg-1 for 3 days. Also the transfer of resistance to A. pubiflora poisoning was evaluated by transfaunation of rumen fluid (100ml for 10 days) from G1 sheep to five sheep (G2),... |

| ABSTRACT: The objective of this study was to describe the epidemiological, clinical, and pathological aspects of Palicourea aeneofusca poisoning in cattle in the region of Pernambuco, Brazil and to determine if it is possible to induce food aversion by P. aeneofusca poisoning in cattle raised under extensive management conditions. To determine the occurrence of poisoning, 30 properties were visited in five municipalities of the region of Pernambuco. Three outbreaks of poisoning of cattle were monitored. To induce conditioned food aversion by the consumption of P. aeneofusca, 12 animals were randomly distributed into two groups of six animals each. Cattle were weighed and received green P. aeneofusca leaves in their trough at a dose of 35mg kg-1 body weight... |
