Aflatoxicosis in horses.
Two episodes of acute aflatoxin poisoning in horses suggest that horses are susceptible to the toxic effects of this mycotoxin. Lesions associated with exposure to aflatoxin included encephalomalacia of cerebral hemispheres, fatty degeneration, necrosis, bile duct hyperplasia, fibrosis of the liver, fatty infiltration of the kidney, hemorrhagic enteritis, and myocardial degeneration. Hypoglycemia, hyperlipidemia, and depletion of lymphocytes accompanied these lesions. The diagnosis was based on gross and histopathologic observations, consistent with observations of other species poisoned with aflatoxin, and isolation of the toxin from feed and animal tissues. Removing contaminated feed prevented further morbidity or mortality.
