Cutibacterium acnes JCM 18920

Cutibacterium acnes JCM 18920 is a Gram-positive, rod-shaped bacterium categorized as an anaerobe. This species is distinguished by its lack of mobility, despite the presence of flagella. It thrives optimally at a temperature of 37°C and falls within the mesophilic temperature range. C. acnes JCM 18920 is nonsporulating and exhibits a free-living biotic relationship. The organism possesses a single replicon and is characterized by one membrane structure. Its habitat is primarily host-associated, indicating a close relationship with its host environment, which is often the human skin. This association is significant as C. acnes is commonly found in sebaceous glands and is known for its role in skin health and conditions such as acne. Understanding the traits of Cutibacterium acnes JCM 18920 provides insights into its ecological role within the human microbiome. Its anaerobic nature and optimal growth temperature suggest it is well-adapted to the microenvironments found in hair follicles, where oxygen levels are low. The presence of this bacterium can influence skin conditions and the overall microbial balance on the skin, highlighting its importance in both health and disease contexts.
