凝固酶阴性葡萄球菌(CNS)作为人体皮肤表面正常寄居菌群之一,被认为是无侵袭性、低毒力的条件致病菌[1]。路邓葡萄球菌作为CNS中的一种,由Freney等[2]于1988年首次报道,它常被作为培养污染菌,因此一般实验室只将其鉴定到CNS水平上,而不再进一步鉴定。然而近年来,路邓葡萄球菌引 Coagulase-negative staphylococcus aureus (CNS), one of the normal colonies on human skin surface, is considered to be a non-invasive, low-virulent opportunistic bacterium [1]. Staphylococcus aureus, a species of CNS, was first reported in 1988 by Freney et al. [2]. It is often used as a culture of contaminated bacteria. Therefore, most laboratories only identify it to the level of CNS without further identification. However, in recent years, Deng Road Staphylococcus cited
