Abstract

Information on the prevalence of S. aureus and the current antimicrobial resistance profile is necessary in selecting the appropriate treatment of S. aureus infections in any part of the world. This study examined the frequency and antibiotic resistance list of S. aureus isolates obtained from clinical specimens at one hospital in Korea. A total of 1,746 gram positive cocci collected were identified as S. aureus. S. aureus isolates were obtained from different samples including sputum (N=565; 32.4%), endotracheal aspirate (358; 20.5%), wounds (329; 18.8%), blood (137; 7.8%), urine (67; 3.8%), and pus (59; 3.4%). All 1,545 S. aureus (100%) strains screened from sputum (565; 36.6%), endotracheal aspirate (388; 25.1%), wounds (329; 21.3%), blood (137; 8.9%), urine (67; 4.3%), and pus (59; 3.8%) were sensitive to glycopeptide (vancomycin, teicoplanin), oxazolidinone (linezolid) and stretogramin (quinupristin/dalfopristin). The prevalence of resistant S. aureus was significantly (P<0.01) lower in urine, blood, pus, wounds, and sputum than in endotracheal aspirates. As a result, there was a significant difference in the antibiotic resistance of S. aureus according to the clinical specimens.

황색포도상구균의 유병률에 대한 정보와 항생제 내성 리스트는 전 세계 어느 곳에서나 황색포도상구균 감염의 적절한 치료 방법을 선택하는 데 필요하다. 이 연구는 한국의 어느 병원 임상 검체에서 얻은 황색포도상구균 균주의 빈도와 항생제 저항성을 조사하기 위하여 수행하였다. 그람 양성구균 1,746 개의 균은 S. aureus으로 확인되었다. S. aureus은 객담(N=565, 32.4%), 기관내 흡인(358, 20.5%), 상처(329, 18.8%), 혈액(137명, 7.8 %), 고름(59 %, 3.4 %)이었다. 객담, 기관 내 흡인, 상처, 혈액, 소변 및 고름에서 스크리닝 된 1,282개의 S. aureus 균주 모두 글리코 펩타이드 옥시 졸리 디논(리네 졸리드) 및 스트렙토그라민(퀴뉴프리스틴/달포프리스틴)에서 모두 민감성이 나타났다. 황색 포도상 구균은 기관 내 흡인과 비교하면 소변, 혈액, 고름, 상처 및 객담에서 내성이 유의하게 낮았으며(P<0.01), 기관내 흡인 검체에서 분리 된 황색포도상 구균의 경우 특히 내성의 빈도가 높았다. 결과적으로, 임상 표본에 따라 황색 포도상 구균의 항생제 저항성에는 상당한 차이가 있었다.
