The complete annotated genome sequences of three Campylobacter jejuni strains isolated from naturally colonized, farm raised chickens.

Interpretive Summary: In the United States, Campylobacter jejuni is the predominant species associated with human illness, accounting for >99% of all reported infections. Many wild, domesticated, and farm animals are carriers of C. jejuni, especially birds. Human C. jejuni infections are primarily due to the handling and consumption of contaminated poultry products, with water and milk also serving as sources of infection. To better understand the epidemiology of C. jejuni in farm animals, specifically chickens, three C. jejuni isolates were obtained from three different Rainbow Ranger broiler chickens and their genomes were sequenced. Interestingly, all three strains harbor a distinct megaplasmid containing tet(O), which is associated with tetracycline resistance.

Technical Abstract: Campylobacter jejuni is a leading cause of bacterially derived foodborne illness worldwide. Human illness is commonly associated with handling and consumption of contaminated poultry products. Three C. jejuni strains were isolated from cecal contents of three different naturally colonized, farm raised chickens. This study describes the complete annotated genomes of these three chicken isolates.
