Antimicrobial Susceptibility Patterns and Conjugation Characteristics of Escherichia Coli Isolates From Broiler and Indigenous Chicken in Kericho County, Kenya

Abstract

Improper use of antibiotics is a leading factor in promoting emergence, Resistance in E. coli decreased with increase in the age of broiler chicken while the opposite was in those from indigenous. Plasmids were transferrable pointing to similar transfers in natural settings. No correlation between rate of resistance and number of plasmids, whereas a positive correlation between rate of resistance and size of plasmid band was found.
