Abstract
Molecular markers have over the years permitted the rapid identification, phylogenetic classification and antimicrobial resistance profile of microbial taxa as compared to the traditional culture method. Through molecular analysis of 16S rRNA gene, this study investigated the molecular and genetic differences that exist between E. coli isolated from local scavenging chicken in relation to their pathogenicity and antimicrobial resistance. Our analysis revealed that E. coli samples from the two different housing systems showed significant genetic diversity and we postulated that this is attributable to the pressure created by vaccines and antimicrobial drugs. The different genetic patterns corresponded to different antimicrobial susceptibility patterns and prevalence of virulence genes. Thus, the 16SrRNA gene can also be used as a molecular marker to indicate the antimicrobial resistance and pathogenicity of chicken.
