Abstract

A new mycotoxin that produces severe tremors and acute toxicity when administered orally or intraperitoneally (ip) to mice and 1-day-old cockerels was obtained from a strain of Penicillium verruculosum Peyronel isolated from peanuts. The ip 50% lethal dose (LD 50 ) of this tremorgen was 2.4 mg/kg in mice and 15.2 mg/kg in chickens. Orally administered LD 50 values for the toxin were 126.7 mg/kg in mice and 365.5 mg/kg in chickens. The trivial name “verruculogen” is proposed for this tremorgenic mycotoxin. Physical and chemical characteristics of the mycotoxin are described.
