Cutibacterium acnes JCM 18909

Cutibacterium acnes JCM 18909 is a Gram-positive, nonsporulating rod-shaped bacterium that thrives in anaerobic environments, with an optimal growth temperature of 37.0 °C. This microbe is primarily host-associated, indicating its adaptation to living in association with human hosts, particularly in skin environments. C. acnes is part of the normal skin microbiota and plays a critical role in maintaining skin health, although its abundance and activity can be influenced by various factors, including skin condition and environmental changes. Its anaerobic nature suggests that it thrives in oxygen-limited niches, such as sebaceous glands, where it can metabolize lipids and contribute to the skin's microbiome. The presence of C. acnes is often explored in relation to skin health and disorders, particularly given its association with conditions like acne. However, it is essential to note that while its presence is consistent in healthy skin, its role can vary depending on the host's skin environment and other microbial interactions. Understanding C. acnes JCM 18909's specific contributions to skin ecology may provide insights into its complex relationship with host health and disease.
