Bifidobacterium longum strain APC1503

Bifidobacterium longum strain APC1503 is a Gram-positive, anaerobic rod-shaped bacterium. It typically exists in clusters, pairs, or singly, and is characterized by the presence of flagella, although it is non-motile. This strain is mesophilic, with an optimal temperature of 37°C, and possesses a single membrane and replicon. Bifidobacterium longum strain APC1503 is primarily associated with various hosts, including Homo sapiens, Metazoa, Sus scrofa, Insecta, Primates, Mammalia, and Vertebrata. It exhibits a free-living biotic relationship, suggesting its ability to thrive in diverse environments within these hosts. Despite its association with health effects, such as bacteraemia, this strain is classified as non-pathogenic, highlighting its potential safety in various applications. Importantly, it does not form spores, which may influence its survival and ecological interactions. In summary, Bifidobacterium longum strain APC1503 exemplifies the complex relationships between microbiota and their hosts, contributing to our understanding of gut health and the overall microbial ecosystem. The strain's adaptability to different environments and its non-pathogenic nature position it as a candidate for further research into its beneficial roles within host species.
