The bacteria found in an acne bump.
The bacterium Propionibacterium acnes (P. acnes for short) is a regular resident of all skin types; it's part of the skin's natural sebum maintenance system. Once a follicle is plugged, however, P. acnes bacteria multiply rapidly, creating the chemical reaction we know as inflammation in the follicle and surrounding skin.
Bacteria that causes acne lesions.
a bacterium naturally found on the human skin that protects from infection and chemically alters skin oil.
Propionibacterium acnes is a relatively slow growing, (typically) aerotolerant anaerobe gram positive bacterium that is linked to the skin condition acne; it can also cause chronic blepharitis and endophthalmitis, the latter particularly following intraocular surgery. The genome of the bacterium has been sequenced and a study of the bacterial genome has shown several genes that can generate enzymes for degrading skin and proteins that may be immunogenic (activate the immune system).
