Faecalibacterium prausnitzii strain CNCM I 4573

Faecalibacterium prausnitzii strain CNCM I 4573 is a Gram-positive, non-sporulating, anaerobic bacterium that exhibits a rod shape. It is a chemoheterotroph, meaning it derives its energy from organic compounds. This species is mesophilic, with an optimal growth temperature of 37°C, and it thrives within a specific temperature range conducive to its metabolic processes. F. prausnitzii strain CNCM I 4573 is notable for its presence in various habitats, including the gastrointestinal tracts of multiple hosts such as Homo sapiens (humans), Gallus gallus (chickens), as well as other Metazoa, Aves, and primates like Macaca mulatta and Macaca fascicularis. This diversity in host range suggests its adaptability and potential role in different biological environments. Despite the absence of mobility, as indicated by the lack of flagella, F. prausnitzii possesses a single replicon, which is characteristic of its genomic structure. The strain's ecological significance lies in its association with gut health, particularly in humans, where it is considered a beneficial microbe that contributes to the maintenance of intestinal homeostasis and may play a role in anti-inflammatory processes. The presence of F. prausnitzii in the gut microbiota is often linked to health benefits, emphasizing its importance in the ecological balance within the intestines of various hosts. Its ability to thrive in anaerobic conditions and utilize organic substrates positions it as a key player in microbial communities, potentially influencing host metabolism and immune responses.
