Environmental Investigation and Genetic Analysis of Nosocomial Transmission of Methicillin-Resistant Staphylococcus aureus

Abstract: Health and Welfare Organization Wakayama Rousai Hospital (2014 年 12 月 24 日 受付・2015 年 4 月 22 日 受理) 要 旨 当院において 2014 年 2 月から 3 月の 1 ヶ月間に,同一病棟において 3 名の患者から methicillin-resistant Staphylococcus aureus (MRSA)が検出された.3 名は入院後 48 時間以降の検出例であ った.さらに,検出同時期に長期入院 MRSA 保菌患者 1 名が同じ病棟に入院していた.これら 4 名から検出された MRSA 株は,薬剤感受性パターン(アンチバイオグラム)と phage open reading frame typing 法による遺伝子学的解析が一致した.我々は院内伝播を疑い,感染経路を明らかにす るために同病棟における環境の MRSA 培養と遺伝子学的解析を実施した.その結果,環境から 4 株の MRSA が検出され,患者由来株のアンチバイオグラムと遺伝子学的解析が同一であった.こ れらのことから,病棟の環境における MRSA の拡散が示唆… Show more

“…The usefulness of POT screening in controlling nosocomial infections has been previously reported. In one of these studies, an environmental investigation was performed during an MRSA outbreak; POT screening of MRSA revealed the infection source and route, resulting in termination of the outbreak [6]. In another study, POT screening was introduced as a method for identifying transmission within 48 h of hospital admission as nosocomial spread [7].…”
