Cutibacterium acnes subsp. acnes

Cutibacterium acnes subsp. acnes is a Gram-positive, anaerobic bacterium characterized by its rod shape and lack of mobility, as it does not possess flagella. This subspecies thrives optimally at a temperature of 37°C, categorizing it as mesophilic, which indicates its preference for moderate temperatures typical of human skin. C. acnes subsp. acnes is classified as free-living, highlighting its ability to exist independently in various environments, particularly on human skin where it is part of the normal microbiota. It is noteworthy that this bacterium has four replicons, which may contribute to its genetic diversity and adaptability in different conditions. The presence of C. acnes subsp. acnes on the skin is significant, as it plays a dual role in human health. While it is generally considered a commensal organism, its overgrowth can be associated with skin conditions such as acne. This duality reflects its potential impact on human health, suggesting that maintaining a balanced skin microbiome is essential for preventing the pathological effects associated with its proliferation. The accessions for this bacterium include CP023676.1, CP044255.1, CP025934.1, and AP019723.1, which provide genomic data that can further enhance understanding of its biology and ecological interactions within the human microbiome. Overall, C. acnes subsp. acnes exemplifies the complexity of microbial life and its significant role in human health and disease.
