Core essential genes of C. jejuni NCTC 11168. Genes are colored to indicate the COG category. Numbers after the legend indicate percentages of the COG category enriched in the core essential gene list. Soft edge rectangle- various studies: Metris [26], Stahl-Stintzi [25], Gao-O [27], JCVI-syn3-H [24], CJ-81176-O: C. jejuni 81–176 (this study), and CJ-11168: C. jejuni NCTC 11168 (this study). O and H in the study name indicate orthologs and homologs respectively. Genes circled in thick red and thin red are common in six and five studies, respectively. All the genes in this network were identified as essential in at least four of the studies
