Abstract

Propionibacterium acnes, P. avidum, and P. granulosum were quantitatively measured in 50 young adults. The scalp, forehead, external auditory canal, alae nasi, anterior nares, groin, rectum, and antecubital and popliteal fossa were sampled. These represent various cutaneous microenvironments, differing in moisture, density of sweat, sebaceous glands, and extent of anaerobiosis. These studies show that the propionibacteria are ubiquitous on the skin, with P. acnes predominant in both prevalence and population, especially in areas rich in sebum. P. granulosum recovery paralled that of P. acnes, but the density was significantly lower. P. avidum was found mainly in moist areas and the retum, suggesting an intestinal reservoir.

摘要

对50名年轻成年人的痤疮丙酸杆菌、嗜丙酸杆菌和颗粒丙酸杆菌进行了定量测定。对头皮、前额、外耳道、鼻翼、前鼻孔、腹股沟、直肠以及肘前窝和腘窝进行了采样。这些部位代表了不同的皮肤微环境,在湿度、汗腺密度、皮脂腺以及厌氧程度方面存在差异。这些研究表明,丙酸杆菌在皮肤上普遍存在,痤疮丙酸杆菌在患病率和菌量上均占主导,尤其是在皮脂丰富的区域。颗粒丙酸杆菌的检出情况与痤疮丙酸杆菌相似,但密度显著较低。嗜丙酸杆菌主要存在于潮湿部位和直肠,提示肠道是其储存库。
