본 연구에서는 식품에서의 L. monocytogenes에 대한 기 초자료를 제공하고자 2010년부터 2011년까지 서울지역에서 수거된 식품 총 1042건에서 L. monocytogenes를 분리 하여 항생제 감수성 검사를 하였다. 김밥 4건(0.8%), 육회 4건(2.6%), 연어제품 2건(11.1%), 돈육식품과 조리된 생선에서 각 1건씩(각5.9%, 6.3%) 총 12균주가 분리 동정되었다. 분리 균주를 20종의 항생제에 검사한 결과 대다수 항생제(16종)에 감수성을 나타내었지만 cefotetan (11균주), cefotaxime (7균주), cefepime (6균주)에서 내성을 나타냈으며 3균주에서 임상치료에 자주 사용되는 tetracycline에 대해서 내성을 나타내었다.

Listeria monocytogenes continues to be a important food safety concern. The aims of the present study were to investigate the prevalence and antimicrobial susceptibility of L. monocytogenes. A total of 1,042 samples was collected from 2010 to 2011 in Seoul and twelve L. monocytogenes were isolated. Isolation rate was Gimbap (0.8%), Beef (yukhoe) (2.6%), Pork (cooked) (5.9%), Fish(cooked) (6.3%), and Salmon (11.1%), respectively. In this study, most of the isolates were susceptible to antibiotics. The most common resistance was cefotetan on 11 isolates, followed by cefotaxime on 7 isolates, cepefime on 6 isolates and tetracyclin on 3 isolates.
