Plasmids and antimicrobial susceptibility of Escherichia coli with special reference to poultry isolates in Sarawak

Son R., . and Gulam R. R. A., . Plasmids and antimicrobial susceptibility of Escherichia coli with special reference to poultry isolates in Sarawak. pp. 21-25. ISSN 9128-2506

A total of forty six strains of Escherichia coli from poultry sources were examined for the occurrence of plasmid DNA in association with their susceptibility to nine antimicrobial agents. Of all the E. coli surveyed 35 (16 of 46) contained plasmid DNA ranging in size from 1.5 to 64 megaDalton (mDa). Antibiotic susceptibility for the 46 poultrty isolates indicated that most isolates were resistant to ampicillin erythromycin streptomycin trimethoprim-sulfamethoxazole sulfonamide and tetracycline and no isolates were susceptible to penicillin G. More isolates containing plasmids were resistant to ampicillin erythromycin streptomycin sulfonamide trimethoprim-sulfamethoxazole and tetracycline. In addition six selected resistant E. Coli poultry isolates were found to transfer enbloc their antimicrobial resistance phenotypes with the concomitant transfer of all their respective donors plasmid species to the recipient E. coli K12 NA1r which suggested a possible relationship between plasmid carriage and resistance to the antimicrobial agents tested.

Abstract

A total of forty six strains of Escherichia coli from poultry sources were examined for the occurrence of plasmid DNA in association with their susceptibility to nine antimicrobial agents. Of all the E. coli surveyed 35 (16 of 46) contained plasmid DNA ranging in size from 1.5 to 64 megaDalton (mDa). Antibiotic susceptibility for the 46 poultrty isolates indicated that most isolates were resistant to ampicillin erythromycin streptomycin trimethoprim-sulfamethoxazole sulfonamide and tetracycline and no isolates were susceptible to penicillin G. More isolates containing plasmids were resistant to ampicillin erythromycin streptomycin sulfonamide trimethoprim-sulfamethoxazole and tetracycline. In addition six selected resistant E. Coli poultry isolates were found to transfer enbloc their antimicrobial resistance phenotypes with the concomitant transfer of all their respective donors plasmid species to the recipient E. coli K12 NA1r which suggested a possible relationship between plasmid carriage and resistance to the antimicrobial agents tested.
