ESBL producing <em>Escherichia coli</em> prevalence in chicken stools in selected broiler farms in Galle district

Introduction: Most of the animals reared for food are reservoirs Extended Spectrum Beta-lactamase (ESBL) producing coliforms. ESBL Escherichia coli (E. coli) in chicken meat increasing worldwide. Since consumption meals is higher compared to other livestock Sri Lanka, there a threat transmit these organisms humans via food. The aim this study was determine E. prevalence stools and presence antibacterial substances feed water selected broiler farms Galle district Methods: Eighty stool samples were collected from district. Isolates confirmed as on lactose fermentation, colony morphology, Gram staining biochemical tests. production detected according CLSI double disc diffusion method. Ready serve tested against two types control cultures using agar well method detect effects any substances. Results: Eighty-six different isolated 80 samples. There no producers among all E coli. activity demonstrated or served except one farm. percentage distribution fecal microbial flora their density altered farm where antibiotics used feed. Conclusions: No indicating minimum risk transmission ESBLs human meat.
