Abstract

DURING the past three decades occasional reports have appeared in which ingestion of feeds contaminated with Fusarium has been associated with a variety of toxic syndromes in domestic animals. Loginov (1958) reported death of newly weaned pigs within 2 to 3 days with symptoms of acute catarrhal inflammation of naso-pharynx, stomatitis, pulmonary edema and liver dystrophy. Fusarium sporotrichoides var. minus was isolated from moldy wheat bran which caused this condition. Nelson, Christensen and Mirocha (1965) reported that molds of the genus Fusarium were the common and major cause of an estrogenic syndrome in swine involving the genital tracts of both sexes. Curtin and Tuite (1966) proposed three distinct active metabolites being produced by Gibberella zeae, one anabolic and causing uterine hypertrophy, one with emetic activity and one causing refusal to consume the contaminated feed.

The object of this study was to determine the toxicity of autoclaved corn inoculated with cultures of Fusarium (Gibberella) roseum Ohio Isolate C when fed to swine and laboratory animals.
