Figure 7: Candidate genes implicated in growth in the pig gastrointestinal tract.

(a) Circular diagram of the C. jejuni M1cam genome with genes required during pig infection indicated in red. No distinct clustering was observed except for several genes located in the flagellar (glycosylation) locus and genes encoding an ABC-type branched-chain amino acid transporter system (livMHKJ). (b) Functional class enrichment analysis of genes linked to piglet infection. Bars display the number of genes assigned to each COG category that were required during infections of pigs, with the percentage of genes per COG given on the top of each bar. COG functional class enrichment was analysed using a Fisher-exact test and corrected for multiple testing using Q-value50, ***Q < 0.001.
