From the nares of 11 healthy adults, 253 strains of coagulase negative staphylococcus were isolated and 88% of them were identified as Staphylococcus epidermidis using the API STAPH system. Chromosomal DNA fingerprinting of the isolated strains revealed that each person carried multiple types of S. epidermidis in his or her nares. The colonization of the strains was not stable; the types of the isolates changed in the first and the second examinations 5 months apart. The results contrasted with previous findings in which only one strain of S. aureus colonized persistently in the nares of healthy adults.
从11名健康成年人的鼻腔中分离出253株凝固酶阴性葡萄球菌，使用API STAPH系统将其中88%鉴定为表皮葡萄球菌。对分离菌株进行染色体DNA指纹分析显示，每个人的鼻腔中都携带多种类型的表皮葡萄球菌。这些菌株的定植并不稳定；在相隔5个月的第一次和第二次检查中，分离株的类型发生了变化。该结果与之前的研究结果形成对比，之前的研究发现健康成年人鼻腔中仅持续定植一株金黄色葡萄球菌。
