Bifidobacterium longum strain APC1461

Bifidobacterium longum strain APC1461 is a Gram-positive, non-pathogenic anaerobic bacterium characterized by its rod shape and non-motility. It typically exists in clusters, pairs, or singles and exhibits a mesophilic growth range, with an optimal temperature of 37°C. This strain has one replicon and a single membrane, suggesting a straightforward genetic and cellular structure. B. longum APC1461 is associated with various hosts, including Homo sapiens, Metazoa, Sus scrofa, Insecta, Primates, Mammalia, and Vertebrata, highlighting its versatility and adaptability within different biological systems. The strain is free-living, which implies it can thrive independently in its environments. While the strain is generally considered beneficial, it is important to note that it has been linked to cases of bacteraemia, indicating a potential health concern under specific conditions. However, its non-pathogenic nature suggests that it does not typically cause disease. Ecologically, Bifidobacterium longum plays a significant role in the gut microbiota of its hosts, contributing to digestive health and the maintenance of microbial balance. Its ability to coexist in various animal and human hosts underscores its importance in microbiological research and potential applications in probiotic therapies. The strain's resilience and functional roles in diverse ecosystems reflect its evolutionary success and importance in microbiome studies.
