Methicillin-resistant Staphylococcus aureus (MRSA) continues to be an important nosocomial pathogen. Various hospital-based studies have described the incidence of MRSA and carriage of this organism in health care workers. Recently, even community acquired S. aureus strains have shown resistance to methicillin. This changing epidemiology prompted us to study the nasal carriage of MRSA amongst healthy individuals in a community. A total of 319 nasal swabs were taken from both anterior nares of healthy parents attending a well-baby clinic. Of these, 94 yielded growth of S. aureus (29.4%). Out of these 94 isolates, 17 (18.1%) were found resistant to oxacillin. These strains showed low level resistance only to clindamycin.
耐甲氧西林金黄色葡萄球菌（MRSA）仍然是一种重要的医院病原体。各种基于医院的研究已经描述了MRSA的发病率以及医护人员中该菌的携带情况。最近，甚至社区获得性金黄色葡萄球菌菌株也显示出对甲氧西林耐药。这种不断变化的流行病学情况促使我们对社区中健康个体的MRSA鼻腔携带情况进行研究。我们从一家母婴健康门诊的健康父母的双侧前鼻孔共采集了319份鼻拭子。其中，94份培养出金黄色葡萄球菌（29.4%）。在这94株分离株中，17株（18.1%）被发现对苯唑西林耐药。这些菌株仅对克林霉素表现出低水平耐药。
