Five hundred fifty three patients and two personnel (1986-1991) were categorized according to acquisition route of methicillin-resistant Staphylococcus aureus (MRSA) and initial culture date. Of the 555, there were 218 with nosocomial infections, 100 with nosocomial colonizations, 92 with community-acquired infections, and 145 with community-acquired colonizations. Nosocomial infections occurred significantly more often than nosocomial colonizations, community-acquired infections, or colonizations (p < 0.001). Results of this study show that over a long period, our patients acquired MRSA by different routes, none of which were related to seasons of the year. Although seasonal outbreaks of epidemic MRSA are important, an awareness of the occurrence of endemic MRSA is also important because it serves as a reminder that MRSA reservoirs are continuously present in some institutions.
根据耐甲氧西林金黄色葡萄球菌（MRSA）的获得途径和初次培养日期，对553例患者和2名工作人员（1986 - 1991年）进行了分类。在这555例中，有218例发生医院感染，100例为医院定植，92例为社区获得性感染，145例为社区获得性定植。医院感染的发生明显比医院定植、社区获得性感染或定植更为频繁（p < 0.001）。本研究结果表明，在很长一段时间内，我们的患者通过不同途径获得MRSA，其中没有一种与一年中的季节相关。虽然流行性MRSA的季节性暴发很重要，但认识到地方性MRSA的发生也很重要，因为它提醒人们，在一些机构中MRSA储存库持续存在。
