The putative global posttranscriptional regulator csrA was mutated in Campylobacter jejuni 81-176. The csrA mutant was attenuated in surviving oxidative stress. CsrA also contributed to biofilm formation and adherence to and invasion of INT407 intestinal epithelial cells, suggesting a regulatory role for CsrA in C. jejuni pathogenesis.
