Cutibacterium acnes JCM 18918

Cutibacterium acnes JCM 18918 is a Gram-positive, anaerobic bacterium characterized by its rod shape and a single membrane. This species is non-motile and does not form spores, indicating a stable lifestyle without the need for dispersal through sporulation. The optimal temperature for growth is 37°C, placing it within the mesophilic range, which is typical for many human-associated microorganisms. C. acnes is associated with host environments, exhibiting a free-living biotic relationship. This suggests it can thrive in the presence of a host, likely contributing to its role in human skin microbiota. Its singular replicon indicates a streamlined genetic structure, which may facilitate efficient metabolic processes under anaerobic conditions. The presence of flagella, despite its non-motility, could suggest evolutionary remnants or potential roles in environmental adaptation, although this does not confer mobility to the organism. Understanding the characteristics of C. acnes JCM 18918 can provide insights into its ecological role, particularly in relation to human skin health and disease. Given that it is part of the normal skin flora, this bacterium may influence skin conditions and contribute to maintaining a balanced microbial community. Its unique traits highlight the complexity of host-associated microorganisms and their potential impact on human health.
