Abstract

The present study was conducted to investigate the biochemical properties, pathogenicity, antimicrobial test, and serotype of E-coli isolated from slaughtered cattle during the period from March 1991 to May 1991. 1. A total of 12 E-coli isolates were isolated from 132 bile juice of slaughtered cattle. 2. All isolates were resistant to Erythromycin, Cephalothin, Neomycin and Lincomycin while the majority of them were susceptible to Trimethoprimsulfamethoxazol (67%), Chloramphenicol(58％), Gentamicin(58%), Ampicillin(17%), Kanamycin(9%) and Tetracycline (9%). 3. In the test of colicinogenecity and congo-red binding capability, 4(33%) isolates produced colicin, all isolates were congo-red negative. 4. The serotypes of isolated E-coli were identified as 008： K- (2 strain), 015： K- (1 strain), 08： K87： K88ab(1 strain), 0139： Kl2(1 strain), 0147: K89(1 strain), others(6 strains ) were autoagglutination.
