a
pUCAB and pUCCDE contain the sdeAB and sdeCDE loci, respectively, cloned into vector pUC18.
b
Relative MIC is the MIC value obtained for the test strain divided by the MIC value of E. coli AG102MB. CIP, ciprofloxacin; NOR, norfloxacin; OFX, ofloxacin; CHL, chloramphenicol; EtBr, ethidium bromide.
