Metronidazole resistance in Campylobacter jejuni from poultry meat

The occurrence of metronidazole resistance was investigated among Campylobacter jejuni in raw poultry meat collected from supermarkets. MICs were determined by the agar dilution procedure in the testing range of 3 to 60 microg/ml metronidazole. The MICs showed a bimodal distribution with a significant proportion of metronidazole-resistant isolates among C. jejuni from raw broiler and turkey meat. Metronidazole resistance occurred most frequently among turkey meat isolates (P < 0.005). This is the first report of foodborne bacteria carrying metronidazole resistance.
