Bifidobacterium longum subsp. longum strain MCC10003

Bifidobacterium longum subsp. longum strain MCC10003 is a Gram-positive, rod-shaped bacterium that thrives in anaerobic environments. This strain is predominantly associated with host organisms, specifically Homo sapiens and other primates, and exhibits a unique cell arrangement characterized by clusters, pairs, and singles. As a mesophilic organism, it optimally grows at 37°C, which aligns with the body temperature of its hosts. This strain is non-motile, lacking flagella, which indicates that it does not possess the means to move independently. Instead, Bifidobacterium longum subsp. longum MCC10003 primarily exists in a free-living state within the gastrointestinal tract of its hosts. The presence of a single replicon and one membrane further illustrates its simple cellular structure, typical of many bacteria in the Bifidobacterium genus. The ecological role of Bifidobacterium longum subsp. longum MCC10003 in the gut microbiome is significant, as it contributes to the maintenance of gut health and the balance of intestinal flora. Its ability to thrive in the human gut suggests a symbiotic relationship where it may aid in digestion and provide essential nutrients to its host, enhancing overall well-being. The strain's adaptations to its anaerobic habitat and its association with primates highlight its importance in the study of host-microbe interactions and the development of probiotics.
