Which bacteria are related to acne?

The bacteria most commonly associated with acne is Propionibacterium acnes, which is often abbreviated as P. acnes. This bacterium lives on the skin and is a normal part of the skin flora. When the pores of the skin become clogged with excess oil and dead skin cells, the environment becomes conducive for P. acnes to proliferate. In this environment, it can lead to inflammation and the formation of acne lesions.

C. Acne could refer to Cutibacterium acnes, which is the newer classification name for Propionibacterium acnes. Both of these refer to the same bacterium linked to acne, thus making it significant in discussions about acne treatments and management.

Choosing an answer that includes both P. acne and C. acne correctly captures the two related names for the same bacterium involved in acne development. This understanding is crucial for recognizing how bacterial activity contributes to skin conditions like acne.
