Faecalibacterium prausnitzii strain CNCM I 4575

Faecalibacterium prausnitzii strain CNCM I 4575 is a Gram-positive, non-sporulating anaerobic bacterium characterized by its rod shape and lack of mobility. This strain is a chemoheterotroph, deriving its energy from organic compounds, which is typical for many gut-associated microorganisms. It thrives optimally at 37°C, placing it within the mesophilic temperature range. This strain has been identified in multiple habitats, particularly within the gastrointestinal tracts of various hosts, including Homo sapiens (humans), Gallus gallus (chickens), and several species of primates, such as Macaca mulatta and Macaca fascicularis. The presence of this bacterium across diverse Metazoa and Aves highlights its ecological significance and adaptability within different digestive environments. Faecalibacterium prausnitzii is notable for its role in gut health, often associated with anti-inflammatory properties and a potential protective effect against various gastrointestinal disorders. Its non-motility and anaerobic nature suggest a specialized niche within the gut microbiota, where it likely interacts with other microbial inhabitants and contributes to the maintenance of a balanced intestinal ecosystem. Overall, the ecological presence of Faecalibacterium prausnitzii strain CNCM I 4575 underscores its importance in the microbiome, particularly in relation to human health and disease prevention. The specific energy source and habitat preferences of this strain reflect its adaptive strategies and functional contributions to its hosts.
