Abstract:
92 E. coli isolates were from 241 chickens which were suspected to be colibacillosis from 23 poltry farms in 10 main chicken raising area in Tianjin. Study indicated that the characteristics of pathogen were in accordance with the microbiological property of E. coli. They were more sensitive to gentamicin,acidi flupiperi,chloromycetin,although there were some difference in pathogenic activity among the isolates. The serum types of all isolates were identified by "O" antisera, belonging in 25 types, mainly in the O111, O89, O86, 030, O78. The isolates selected from major types were reliable in antigenicity.
