Bifidobacterium adolescentis strain AD2-8

Bifidobacterium adolescentis strain AD2-8 is a Gram-positive, rod-shaped bacterium that thrives in anaerobic conditions, making it well-suited for host-associated environments. This strain exhibits a single-cell arrangement and does not exhibit mobility, as it lacks flagella, despite their presence in other contexts. It is classified as non-sporulating and is mesophilic, with an optimal growth temperature of 37°C. The strain has been identified in various hosts, including Homo sapiens (humans), Bos taurus (cattle), Sus scrofa (pigs), and Oryctolagus cuniculus (rabbits). This suggests a significant ecological flexibility and potential for mutualistic relationships within diverse gastrointestinal microbiomes. The presence of a single replicon and one membrane indicates a streamlined genomic structure, which may contribute to its adaptability in various host environments. Bifidobacterium adolescentis is categorized as free-living, suggesting that while it can exist independently, it is intricately linked to the health and functionality of its hosts' microbiomes. This bacterium plays a critical role in the gut ecosystem, potentially aiding in digestion and influencing the host’s immune response. Its adaptability and presence in multiple host species highlight the importance of Bifidobacterium adolescentis strain AD2-8 in maintaining microbial diversity and health in gut environments.
