To assess the prevalence and risk factors for colonization with Staphylococcus aureus in inmates entering two maximum-security prisons in New York State, USA, inmates (N=830) were interviewed and anterior nares and oropharyngeal samples collected. Isolates were characterized using spa typing. Overall, 50·5% of women and 58·3% of men were colonized with S. aureus and 10·6% of women and 5·9% of men were colonized with MRSA at either or both body sites. Of MSSA isolates, the major subtypes were spa type 008 and 002. Overall, risk factors for S. aureus colonization varied by gender and were only found in women and included younger age, fair/poor self-reported general health, and longer length of prior incarceration. Prevalence of MRSA colonization was 8·2%, nearly 10 times greater than in the general population. Control of epidemic S. aureus in prisons should consider the constant introduction of strains by new inmates.
为评估美国纽约州两所最高安全级别监狱新入监囚犯金黄色葡萄球菌定植的流行率和危险因素，对 830 名囚犯进行了访谈并采集了前鼻和口咽拭子。采用 spa 分型对分离株进行了特征分析。总体而言，50.5%的女性和 58.3%的男性在前鼻和/或口咽部位定植了金黄色葡萄球菌，10.6%的女性和 5.9%的男性定植了耐甲氧西林金黄色葡萄球菌（MRSA）。MSSA 分离株的主要亚型为 spa 型 008 和 002。总体而言，金黄色葡萄球菌定植的危险因素因性别而异，仅在女性中发现，包括年龄较小、自我报告的一般健康状况一般或较差，以及先前监禁时间较长。MRSA 定植率为 8.2%，几乎是普通人群的 10 倍。监狱中应考虑通过新囚犯不断引入流行株来控制金黄色葡萄球菌的流行。
