[Propionibacterium acnes in acne vulgaris (comparative biochemical study of the comedone and the pustule].

The biochemical properties of the Propionibacterium acnes in 22 patients with inflammatory Acne vulgaris was studied. Group I/II was found in most cases. There was no difference between the biochemical properties of the comedone and the pustule. The authors suggest that factors other than those depending on the PA degradative metabolism can be responsible for the purulent inflammatory process of the pil-sebaceous follicle.
