Biological characteristics of Escherichia coli isolatep from pigeons



Abstract
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 Taegn province.
Of the 166 strains isolated, 28 strains (16.9%) were classified into 6O 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 hemolptic and 3(1.8%) were colicinogenic.
Antibiotie 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.
