Genes encoding transcription and translation machinery (infC, yfiA, rpoA, rhoI, tufA, fusA, tufB, efp), F0F1 ATPase components (atpE, atpF), fatty acid biosynthesis factors (acpP, fabI), protein folding and secretion apparatus (slyD, secG, prlA), and outer membrane components (ompA) were among the most highly expressed during human infection. This evidence concerns the gene DNAH8 and infection.
