Abstract
|
|
|
|
The present study was conducted to investigate serologic characteristics, antimicrobial resistance and plasmid profile of 79 E. coli isolated from faecal sample of the wild bird in Busan province (Gangseo, Saha) during the period from November 2004 to February 2005. Many strains were positive for rafiinose (63.3%), sorbitol (96.2%), sucrose (73.4%) and few strains were positive for esculin, arginine dihydrolase, ornithine decarboxylase. Among 79 isolates, O serotypes were O55, O158, O18 and 47 strains (59.5%) were resistant to antimicrobial drugs such as tetracycline (40.5%), carbenicillin (27.8%). 15 strains showed 14 different plasmid bands composed of 1 to 6 bands. They were ranged from 1.6 to 43 kb and harbored 43 kb (11.4%), 5.3 kb (6.3%) and 11.4 kb (5.1%). Plasmid profile of 15 strains were 43 profile (2.5%), 2.4, 43 profile (2.5%) and 5.3, 11.4, 43 profile (2.5%).
