Abstract

A method allowing isolation and microbiological analysis of individual pilosebaceous units (follicles) was used to study biopsies of back skin obtained from volunteer acne vulgaris patients. The main microbial groups isolated were members of the genera Propionibacterium, Staphylococcus and Pityrosporum. The incidence (and mean density) of these organisms in 140 normal follicles was 12% (2.6 X 10(5) per follicle), 4% (5.5 X 10(3) per follicle) and 13% (10(2) per follicle) respectively. Colonized follicles were not distributed evenly amongst the subjects studied. The results are analysed and discussed from an ecological standpoint.

摘要

一种允许对单个毛囊皮脂腺单位（毛囊）进行分离和微生物分析的方法被用于研究从寻常痤疮患者志愿者身上获取的背部皮肤活检样本。分离出的主要微生物类群是丙酸杆菌属、葡萄球菌属和马拉色菌属的成员。这些微生物在140个正常毛囊中的发生率（以及平均密度）分别为12%（每个毛囊2.6×10⁵）、4%（每个毛囊5.5×10³）和13%（每个毛囊10²）。被定植的毛囊在研究对象中分布并不均匀。从生态学角度对结果进行了分析和讨论。
