Lipophilic corynebacteria isolated as natural flora of human skin were examined. Among 119 assayed strains 94% presented a hydrophobic cell surface and 75.6% were able to form biofilms. These attributes, as well as aggregation in liquid media, were statistically connected with each other and promote the developing of biofilms on solid surfaces. This was characteristic of all the lipophilic Corynebacterium species found on human skin that were examined in this study. C. jeikeium and CDC group G2 strains dominated in this population, and they could be responsible for investigated features in the whole lipophilic skin bacterial population. These two groups are the most common coryneform bacteria isolated from nosocomial infections and these attributes most likely promote them to cause opportunistic infections.
对作为人类皮肤自然菌群分离出的亲脂性棒状杆菌进行了检查。在119株受试菌株中，94%呈现疏水细胞表面，75.6%能够形成生物膜。这些特性以及在液体培养基中的聚集在统计学上相互关联，并促进在固体表面形成生物膜。这是本研究中检测到的人类皮肤上所有亲脂性棒状杆菌物种的特征。杰氏棒状杆菌和CDC G2组菌株在该菌群中占主导地位，它们可能是整个亲脂性皮肤细菌群体中所研究特征的原因。这两组是从医院感染中分离出的最常见的棒状杆菌属细菌，这些特性很可能促使它们引发机会性感染。
