영문 초록

This study was conducted to investigate the antimicrobial susceptibilites and plasmid DNA of L. monocytogenes isolates. Peak distributions of minimum inhibitory concentration (MIC) of the isolates were 0.78㎍/ml for ampicillin and penicillin, 3.13㎍/ml for cephalothin, 6.25㎍/ml for amikacin, and all the isolates were 1.56㎍/ml for vancomycin. Most of 42 isolates were sensitive to ampicillin and penicillin, but isolates were resistant to cephalexin (100%), tetracycline (71.4%), erythromycin (64.3%) and neomycin (50%). Multiple resistance patterns were observed in 64.3% of the resistant strains. The most common resistance patterns were CpxEmTc (28.5%) and CPxEmNmTc (26.2% ). A total of 42 isolates of L. monocytogenes were subjected to the test for the presence of plasmid DNA and 9 strains (14.3%) had single plasmid element. The plasmids recovered from these organisms had molecular weight from 54 or 58 Kb.
