Final answer:
Cutibacterium acnes (C. acnes) is a type of bacteria commonly found on human skin and plays a role in the development of acne.
Step-by-step explanation:
Cutibacterium acnes (C. acnes) is a type of bacteria that is commonly found on human skin. It belongs to the phylum Actinobacteria and is part of the normal microbiota of the skin. C. acnes plays a role in the development of acne, particularly when it infects hair follicles and pores that are clogged with dead skin cells and sebum. The bacteria consume components of sebum and secrete enzymes that can damage the hair follicle, leading to the formation of inflammatory lesions on the skin.
