This work is a study of the acute effects of aflatoxin B1 in dogs. The dog has a remarkable susceptibility to aflatoxin B1 given by oral and intraperitoneal routes. Intraperitoneal administration resulted in the shortest survival time and the most profound pathological changes. However, massive single oral doses produced lesions of similar nature and intensity. Oral administration of aflatoxin in small, divided doses, over extended periods proved to be less toxic. The experimentally induced disease resembled hepatitis X in many respects.
