RESUMEN
Botulism is a well-known intoxication that affects humans and animals. The disease is endemic in cattle in Brazil and recently emerged as an important disease in commercial laying hens and broiler chickens in Europe. Dogs and other animal species can also be affected. Although antitoxins are commonly administered to humans diagnosed with botulism, in animals this is rarely the case and the treatment of botulism is still based only on support therapy. In the present work, we report an outbreak of type C botulism in Brazil that simultaneously affected domestic chickens, dogs and a black-pencilled marmoset (Callithrix penicillata). The successful use of Clostridium botulinum types C and D antitoxin for the treatment of an affected dog is also described.
