Isolation and toxogenic characterization of tri5 positive Fusarium from poultry houses
鸡舍环境中tri5基因阳性镰孢茵的分离及其产毒特性

Objective] We used tri5-PCR technique to identify the toxin-producing Fusarium strains,the toxogenic characteristics and toxicogenic condition of tri5 positive strains.We also evaluated the potential trichothecene-producing level of the Fusarium strains from the air and solid materials in poultry houses.Methods] tri5 gene,the start gene encoding trichothecene synthase,was taken to detect 139 Fusarium isolates by PCR.Toxogenic culture was carried out for tri5 positive Fusarium strains,and the quantities of...
