Bifidobacterium longum NCC2705

Bifidobacterium longum NCC2705 is a Gram-positive, non-motile, and non-sporulating anaerobic bacterium characterized by its rod shape. It is typically found associated with its host, Homo sapiens, and it exhibits a cell arrangement that includes clusters, pairs, and singles. This species thrives optimally at a temperature of 37°C, falling within the mesophilic temperature range, which is conducive to its growth and metabolic functions. The bacterium possesses a single membrane and a singular replicon, indicating a streamlined genomic structure that may contribute to its efficient functioning within the human microbiome. Notably, B. longum NCC2705 is recognized for its free-living biotic relationship, suggesting that while it is closely associated with human hosts, it can also exist independently in certain environments. Importantly, Bifidobacterium longum NCC2705 is not pathogenic, highlighting its potential role as a beneficial microorganism within the human gut microbiota. Its presence may contribute to various health benefits, including digestive health and immune system support. The ecological insight here is that the stability and functionality of the gut microbiome may depend significantly on the presence of such non-pathogenic, beneficial bacteria, which can help maintain a balanced microbial community critical for host health. The accession number for this strain is NC_004943.1, providing a reference for further genomic studies and applications in microbiology.
