Cutibacterium acnes HL110PA4

Cutibacterium acnes HL110PA4 is a Gram-positive, rod-shaped bacterium classified as a nonsporulating anaerobe. This microbe thrives optimally at a temperature of 37.0°C, which aligns with the typical body temperature of its host organisms. As a host-associated bacterium, C. acnes HL110PA4 is commonly found in environments that are closely linked to mammalian skin, where it plays a role in the complex microbiota. The nonsporulating nature of C. acnes HL110PA4 indicates a reliance on stable environmental conditions for survival, which is characteristic of many anaerobic bacteria that inhabit host-associated environments. This organism's anaerobic metabolism suggests a niche adaptation that allows it to thrive in low-oxygen conditions commonly found within hair follicles and sebaceous glands. Furthermore, the presence of C. acnes HL110PA4 in the skin microbiome highlights its potential significance in maintaining skin homeostasis and influencing host immune responses. Its ability to coexist within a diverse microbial community may contribute to the overall health of the skin, although the balance of such interactions can be critical, as disruptions may lead to dysbiosis. This strain exemplifies the intricate relationships between host-associated microbes and their environments, underscoring the importance of understanding microbial traits to elucidate their roles in broader ecological contexts.
