Cutibacterium acnes JCM 18916

Cutibacterium acnes JCM 18916 is a Gram-positive, anaerobic rod-shaped bacterium that is primarily associated with host environments. It thrives optimally at 37°C, falling within the mesophilic temperature range. This species is characterized by having a single circular replicon and a single membrane, indicating a relatively simple cellular structure. Notably, Cutibacterium acnes JCM 18916 does not exhibit mobility, as it lacks flagella despite their presence in some other bacterial species. This organism is nonsporulating, which suggests that it does not form spores as a means of survival under unfavorable conditions. Ecologically, Cutibacterium acnes is recognized for its free-living biotic relationship, indicating its ability to exist independently of a host while still being found in host-associated environments. This bacterium plays a significant role in the human microbiome, particularly on the skin, where it contributes to the maintenance of skin health and the balance of local microbial communities. Its presence can influence skin conditions, highlighting its importance in both health and disease contexts. The accession number for this strain is BAVN00000000.1, which provides a reference for further genetic and phenotypic studies.
