title: Propionibacterium acnes colonization in acne and nonacne.
abstract: Propionibacterium acnes is a number of the resident bacterial flora and resides in sebaceous follicles. Age-related and body-dependent quantitative differences exist, indicating the role of sebum as an important ecological factor for P. acnes. Acne patients demonstrate marked increases in this organism which generates inflammation through a variety of mechanisms.
