背景：近年来，儿童耐甲氧西林无症状金黄色葡萄球菌（MRSA）感染的流行病学发生了变化，越来越多没有MRSA传统危险因素的儿童住院，促使我们确定”无症状”方法：我们对500名在儿科急诊科就诊的儿童的鼻孔和会阴进行培养。其中132例（26.4%）检出沙门氏菌。金黄色。11株（8.3%）S.金黄色葡萄球菌分离株为MRSA; 11例MRSA定植受试者中有4例（36.4%）无危险因素。132个S中有7个（5.3%）。金黄色葡萄球菌是耐甲氧西林的临界菌株。金黄色葡萄球菌（BRSA）; 5（71.4%）的7个主题殖民与BRSA没有MRSA的危险factors.Conclusions。这些研究结果表明，MRSA和BRSA分离株在社区和MRSA分离株循环不再局限于儿童与卫生保健环境的频繁接触。
Background.The recent evolution in the epidemiology of methicillin-resistant asymptomatic Staphylococcus aureus (MRSA) infections in children, whereby children without traditional risk factors for MRSA have been hospitalized in increasing numbers, prompted us to establish whether a parallel increase in" asymptomatic" MRSA colonization had occurred.Methods.We cultured the nares and perineum of 500 children attending our Pediatric Emergency Department.Results.One hundred thirty-two (26.4%) of these children were colonized with S. aureus. Eleven (8.3%) of the S. aureus isolates were MRSA; 4 (36.4%) of the 11 subjects colonized with MRSA had no risk factors. Seven (5.3%) of the 132 S. aureus isolates were borderline methicillin-resistant S. aureus (BRSA); 5 (71.4%) of the 7 subjects colonized with BRSA had no MRSA risk factors.Conclusions.These findings indicate that MRSA and BRSA isolates are circulating in the community and that MRSA isolates are no longer confined to children with frequent contact with a health care environment.
