Material type: materialTypeLabelBookPublisher: 2012Subject(s): Department of MicrobiologyDDC classification: 1477,T Dissertation note: Escherichia coli is normal inhabitant of lower intestinal tract of all warm blooded animals. The background of drug resistant studies on E. coli represent that extensive and irrational use of antimicrobials in human and veterinary sector for treatment, prophylaxis and feed additive made this organism resistant to commonly used antimicrobials. It is assumed that E. coli have the ability to transfer resistant genes via bacterial conjugation, transduction and transformation. As a result pathogenic organisms are also becoming resistant to commonly used antibiotics. And there is a need to check the extent of resistance to ensure the efficacy of antimicrobials used in public health. The purpose of current study was to estimate the prevalence of antimicrobial resistant E. coli in retailed chicken meat samples of Lahore city. In current study hundred chicken meat samples were collected from local market in various areas of Lahore.These samples were processed for isolation of generic E. coli. Initial confirmation of generic E. coliwas made using standard culturing and biochemical reactions. The prevalence rate of E. coli was found 85%. The antimicrobial resistance against in the E. coli isolates was determined by disk diffusion method. All the E. coli isolates were found resistant to at least seven antimicrobials and 34 different antimicrobial patterns were found.
