Diarrhea, disorders in reproductive system, hematological changes like leucopenia trombocyto penia, and pathologic defects like Epithelionecrosisand gastroentritis also would be observed.In a dairy cattle herd in shahriar province, many cases of abortion, diarrhea and blood in the feces were observed.After mycological investigations for other purposes, 30 samples of their ration and vaginal samples which were contaminated with trichothecium samples were cultured in SDA and PDA.There is possibility of trichothecium mycotoxicosis in this herd because the clinical signs disappeared with replacingthe contaminated diet with a clean diet.
