Bifidobacterium longum strain AF13-41

Bifidobacterium longum strain AF13-41 is a Gram-positive, anaerobic bacterium characterized by its rod shape and inability to move, as it lacks flagella. This strain typically exists in clusters, pairs, or singles, and thrives optimally at a temperature of 37°C within a mesophilic temperature range. It has a single replicon and one membrane, and it is free-living. The primary habitat of B. longum strain AF13-41 is host-associated, with a diverse range of hosts including Homo sapiens, Metazoa, Sus scrofa, Insecta, Primates, Mammalia, and Vertebrata. Despite its association with various hosts, this strain is non-pathogenic, although it has been linked to health effects such as bacteraemia. The presence of Bifidobacterium longum strain AF13-41 in the microbiota of humans and other animals suggests its potential role in maintaining gut health and contributing to the overall microbial balance within these ecosystems. The non-pathogenic nature of this strain implies that it may play a beneficial role in its host's health, potentially aiding in digestive processes or supporting immune function. Further exploration of its interactions within the host environment could provide valuable insights into its ecological significance and applications in health-related fields.
