Antimicrobial susceptibility patterns of Escherichia coli isolated from poultry samples at a laboratory in Kenya

Abstract

Bacteria of the genus Escherichia coli, cause Colibacillosis in poultry and are transmitted to humans through handling and/or consumption of contaminated products raising concern over food safety and spread of resistant bacteria. We determined proportion of pathological samples where E.coli was isolated and its antimicrobial susceptibility patterns. From 106 birds and 148 organs, Escherichia coli was isolated in 65% organs with 20% susceptible to Ampicillin, 30% to Tetracycline, 10% to Cotrimoxazole, 20% to Streptomycin, 40% to Kanamycin, 60% to Gentamycin and 10% to Sulphamethoxazole. High proportions of E.coli in samples including resistance to common antibiotics was detected. A holistic approach for prevention, control and treatment of avian Colibacillosis embracing good management, prudent use of antibiotics and utilization of laboratory services are important in controlling infections and overuse of antibiotics reducing resistance development. Enhanced food safety and handling practices are important in preventing spread of the drug resistant genes to human populations.
