摘要:We evaluated the in vitro susceptibility of four serotypes of enterohaemorrhagic Escherichia coli ( E. coli O26, E. coli O111, E. coli O157, and E. coli O165) with diverse DNA patterns to antimicrobial agents. The minimum inhibitory concentrations (MIC) determined in a total of 83 strains using Mueller–Hinton agar under aerobic and anaerobic conditions were 0.015—0.12 μg/ml for ciprofloxacin, 0.06—1 μg/ml for norfloxacin, 2—64 μg/ml for fosfomycin without glucose-6-phosphate (G-6-P), 0.25—32 μg/ml for fosfomycin with G-6-P, 2—256 μg/ml for kanamycin, 0.125—2 μg/ml for cefoperazone, and 0.06—1 μg/ml for ceftazidime. The MIC of ciprofloxacin, norfloxacin, cefoperazone, and ceftazidime were low in all strains examined.
