Propionibacterium acnes (P. acnes) is a ubiquitous, slow growing, rod-shaped, non-spore forming, Gram-positive anaerobe (Figure ​2) found across body sites, including sebaceous follicles of the face and neck (Funke et al., 1997; Grice and Segre, 2011; Findley and Grice, 2014).

Is Propionibacterium acnes a contaminant?

Propionibacterium acnes is often considered a contaminant when it grows in blood culture, akin to the growth of coagulase-negative staphylococci, Bacillus sp., and Corynebacterium sp. In a series of 522 patients with P. acnes bacteremia, only 18 (3.5 %) were considered to have a clinically significant bacteremia [1].

What kills Propionibacterium acnes P. acnes?

Your dermatologist may recommend medical-grade versions of benzoyl peroxide and salicylic acid, as well as retinoids and topical antibiotics. Retinoids not only help dry up the oil and kill P acnes, they help your skin cells turn over to improve the look and health of your skin.
