| 摘 要： | 目的了解老年患者医院下呼吸道感染凝固酶阴性葡萄球菌（CNS）的分布及耐药性特点。方法收集2003-2007年本院老年患者医院下呼吸道感染CNS，进行菌株鉴定和药敏试验，按美国国家临床实验室委员会（NCCLS）标准判断。结果分离出CNS142株，检出率明显超过金黄色葡萄球菌，以溶血葡萄球菌和表皮葡萄球菌为主，分离率最高的是溶血葡萄球菌（43．0％）。甲氧西林耐药率（MR）高达97．9％，万古霉素耐药率为0．0％，2003-2007年，四环素、红霉素、克拉霉素、克林霉素、环丙沙星耐药率呈增高趋势，β-内酰胺类抗生素均呈高水平耐药。结论耐甲西林凝固酶阴性葡萄球菌（MRCNS）成为老年患者下呼吸道医院感染的主要致病菌，多重耐药性现象严重，应加强耐药监测。
