Bifidobacterium longum subsp. infantis EK3

Bifidobacterium longum subsp. infantis EK3 is a Gram-positive, anaerobic bacterium that exhibits a rod shape and typically forms clusters, pairs, or singles. This species is non-motile, meaning it does not have the capability to move independently. It possesses a single membrane and has one replicon. The optimal growth temperature for B. longum subsp. infantis EK3 is 37°C, placing it within the mesophilic temperature range. This bacterium is host-associated, indicating a relationship with specific hosts, likely contributing to the microbiota of the gastrointestinal tract in infants. Its free-living biotic relationship suggests that while it thrives in association with hosts, it can also survive independently in suitable environments. The presence of flagella, despite the lack of motility, raises interesting questions about its cellular structure and evolutionary adaptations. The accession number JNWB00000000.1 provides a reference for further genomic studies. From an ecological perspective, Bifidobacterium longum subsp. infantis EK3 plays a critical role in the gut microbiome, particularly in infants, where it may aid in digestion and nutrient absorption. Its presence is essential for maintaining gut health and may influence the development of the immune system. Understanding the characteristics of this bacterium can help elucidate its functions and contributions to the overall health of its host.
