Known and putative genetic determinants of antibiotic resistance in Campylobacter jejuni strains recovered from two cases of recurrent infections. (n), number of copies; *, allele mixture; **, MIC 10× higher than other susceptible strains (see Table 1); ***, heterogeneous resistance; †, restores TATA box from GAAAAT to TAAAAT in the -10 promoter region; ††, restores the Campylobacter jejuni ribosome binding site (RBS) consensus sequence (AAGGA); †††, affects the Campylobacter jejuni -35 consensus sequence (TTTAAGTnTT); ††††, leads to the loss of a second RBS.
