The purpose of this study was to examine O serotypes, colicin and hemolysin production. antibiotic susceptibility and haemagglutinating ability to animal erythrocytes among Escherichia coli strains isolated from pigeons in Taegu province. Of the 166 strains isolated, 28 strains (16.9%) were classified into 6 O serotypes and their types were O20(42.9%), O15(17.9%), O139(14.3%), O101(10.7%), O149(7.1%) and O8(7.1%). Of the 166 strains isolated, none was hemolytic and 3(1.8%) were colicinogenic. Antibiotic susceptibility test of Escherichia coli isolates was performed by the agar dilution method, using ampicillin, chloramphnicol, gentamicin, rifampicin, streptomycin (Sm), nalidixic acid, sulfadimethoxine and tetracycline (Tc). Forty four strains (26.5%) were resistant to one or more drugs and the most common resistance patterns were SmTc (27.3%). Of the 44 drug resistant strains, 6 strains haemagglutinated erythrocytes of chicken, guinea pig and 2 of the 6 strains agglutinated goose erythrocytes.
