Complete Genome Sequences of Campylobacter jejuni Strains OD267 and WP2202 Isolated from Retail Chicken Livers and Gizzards Reveal the Presence of Novel 116-Kilobase and 119-Kilobase Megaplasmids with Type VI Secretion Systems

Genome sequences of Campylobacter jejuni strains OD267 and WP2202, isolated from chicken livers and gizzards, showed the presence of novel 116-kb and 119-kb megaplasmids, respectively. The two megaplasmids carry a type VI secretion system and tetracycline resistance genes. These are the largest sequenced Campylobacter plasmids to date.
