我们检查了监狱环境表面，以探讨它们是否可能成为活的耐甲氧西林金黄色葡萄球菌 (MRSA) 的储存库。我们擦拭了 132 个表面，接种初级和次级甘露醇盐和苯唑西林抗性筛选琼脂，并使用 API 测试来识别金黄色葡萄球菌，并使用 E 测试来确定甲氧西林/苯唑西林抗性。我们从 10 个（7.6%）表面回收了金黄色葡萄球菌；八株 (6.1%) 分离株为 MRSA。我们对六种耐药菌株进行脉冲场凝胶电泳，观察到三种模式，其中一种与之前对囚犯鼻腔标本的研究中发现的模式相同。在没有明显爆发的情况下，在各种环境表面上发现了 MRSA 污染的表面，这强调惩教设施应该制定环境清洁方案，作为 MRSA 预防的一部分。
We examined jail environmental surfaces to explore whether they might serve as reservoirs of viable methicillin-resistant Staphylococcus aureus (MRSA). We swabbed 132 surfaces, inoculated primary and secondary mannitol salts and oxacillin-resistant screening agar, and used API tests to identify S. aureus and E-tests to determine methicillin/oxacillin resistance. We recovered S. aureus from 10 (7.6%) surfaces; eight (6.1%) isolates were MRSA. We ran pulsed-field gel electrophoresis on six resistant isolates and observed three patterns, one of which was identical to that identified in a previous study of inmates' nasal specimens. Finding MRSA-contaminated surfaces on a variety of environmental surfaces in the absence of an overt outbreak emphasizes that correctional facilities should have protocols for environmental cleaning as a component of MRSA prevention.
