Propionibacterium acnes is a non-sporulating bacilliform (rod-shaped), gram-positive bacterium considered to be the predominant cause of the common inflammatory skin condition acne vulgaris. Although some strains have proven to be aerotolerant P. acnes is primarily anaerobic, found primarily in the pilosebaceous unit (a region that contains the hair follicle and sebaceous gland) of adolescent and adult human skin.
