Bifidobacterium longum subsp. infantis strain TPY12-1 485

Bifidobacterium longum subsp. infantis strain TPY12-1 485 is a Gram-positive, anaerobic bacterium characterized by its rod shape and the arrangement of cells in clusters, pairs, and singles. This strain is non-motile, possessing flagella, and has an optimal growth temperature of 37°C, placing it within the mesophilic temperature range. It has a single replicon and one membrane, indicating its simpler cellular structure compared to more complex organisms. This bacterium is found in host-associated habitats, with a variety of potential hosts that include Homo sapiens, Metazoa, Sus scrofa, Insecta, Primates, Mammalia, and Vertebrata. Its biotic relationship is classified as free-living, suggesting it can survive independently, yet it is also closely associated with various hosts. Notably, Bifidobacterium longum subsp. infantis strain TPY12-1 485 is recognized for its health effects, particularly the potential association with bacteraemia; however, it is categorized as non-pathogenic. This characteristic indicates that, while it may be present in certain health conditions, it does not cause disease in its hosts. The presence of this strain within the gastrointestinal tract of various mammals, including humans, underscores its ecological significance. It plays a role in the gut microbiota, contributing to the overall microbial diversity and health of the host. Understanding such strains can provide insights into the maintenance of gut health and the prevention of dysbiosis.
