Abstract
젓갈로부터 분리된 ampicillin 감수성, coagulase 음성 Staphylococcus 속 17 균주의 항생물질내성 및 위해성을 평가하였다. 15 균주는 한 종류 이상의 항생물질에 대한 내성을 나타내었고, penicillin G 내성 균주가 가장 높은 빈도로 검출되었다. PCR 증폭에 의한 항생물질내성 유전자 존재 확인 결과, trimethoprim 내성 관련 dfrA 유전자와 tetracycline 내성 관련 tetK 유전자를 각각 보유한 두 균주가 확인되었다. α 형 용혈활성은 검출되지 않았지만, 다섯 균주가 δ 형의 용혈을 나타내었고, 그 중 두 균주는 β 형 용혈활성을 나타냈으며, 12 균주가 biofilm을 형성하였다. 본 실험에서 수행한 모든 안전성 평가 결과는 균주 특이적으로 나타났다.
