一株不表达K88、K99、987P粘附因子的鸽源产毒素性大肠杆菌的分离鉴定

Isolation and Identification of a K88,K99,987P Adherence Factors negative E.coli Strain that Produces Enterotoxin from Pigeon

从病鸽尸体中分离出一株大肠杆菌，通过生化试验、血清学鉴定及动物致病性试验，表明该菌是一株具有很强致病力的不表达Ｋ８８、Ｋ９９、９８７Ｐ粘附素的鸽源产毒素性大肠杆菌。

A E.coli strain was isolated from carcasses of Pigeon.It showed that the isolate was highly pathogenic, K88、K99,987P adherence factors negative and enterotoxin producing by biochemistry,sero tests and pathogenicity tests
