Bifidobacterium longum subsp. longum EK13 seq39

Bifidobacterium longum subsp. longum EK13 seq39 is a Gram-positive, non-pathogenic bacterium characterized by its rod shape and absence of mobility, lacking flagella. This species thrives as an anaerobe, with an optimal growth temperature of 37°C, placing it within the mesophilic temperature range. B. longum EK13 seq39 typically forms clusters, pairs, and singles within its habitat, which is host-associated, indicating a close relationship with various hosts. The biotic relationships of B. longum EK13 seq39 are notably free-living, as it can inhabit multiple hosts, including Homo sapiens, Metazoa, Sus scrofa, Insecta, Primates, Mammalia, and Vertebrata. This versatility may contribute to its ecological adaptability and significance in diverse biological systems. Although it is associated with health effects such as bacteraemia, it is important to note that this strain is classified as non-pathogenic, suggesting a role in maintaining health rather than causing disease. With a single replicon and one membrane, B. longum EK13 seq39 exhibits a simple yet efficient cellular structure. Its nonsporulating nature indicates a continuous growth strategy in stable environments, typical of many gut-associated bacteria. The adaptability and non-pathogenic status of B. longum EK13 seq39 underscore its potential role in the microbiota of various hosts, possibly contributing to health maintenance and microbial balance within those ecosystems.
