Iveraldo S. Rosa 4 , Luiz A. The clinical and pathological data, epidemiology and laboratory findings indicate a possible intake of the toxin through contaminated water. The average mortality rate was From about 9, cattle envolved in the outbreaks, 2, animals died, predominantly with a hyperacute and acute clinical picture. The high morbidity rates were observed within a short period and affected all categories of cattle, with a clinical and pathological picture characterized by paresis and paralysis of the muscles of locomotion, swallowing and mastigation, with abscence of gross lesions at post-mortem examination.

Botulismo em bovinos leiteiros no Sul de Minas Gerais, Brasil. Botulism in dairy cattle in southern Minas Gerais, Brazil. E-mail: gmcosta ufla. An outbreak of bovine botulism in a dairy herd caused by ingestion of contaminated maize, in southern Minas Gerais, Brazil is described.
The herd was composed by lactating cows of high milk production fed with diet based on maize ensilage and concentrate in a free stall system. Samples from intestine, rumen and liver of necropsied cattle and drinking water and maize were submitted to the mouse bioassay and soroneutralization tests for detection of Clostridium botulinum toxins.
Types C and D toxins were detected in samples from intestinal and rumen contents and maize. The reporter of an outbreak of botulism in cattle associated with an unusual source of toxin, shows that stocked maize in inadequate conditions is a factor of risk for the occurrence of the botulism in dairy cattle.
