Antimicrobial Resistance of Listeria monocytogenes Isolates from Food and the Environment in France over a 10-Year Period

摘要

In order to assess antimicrobial resistance in Listeria monocytogenes , 202 food and environmental isolates from 1996 to 2006 were tested. Only four strains displayed acquired resistance. Resistance to erythromycin, tetracycline-minocycline, and trimethoprim was evidenced, and the genes erm (B), tet (M), and dfrD , already found in L. monocytogenes , were detected.
