Faecalibacterium prausnitzii strain AF36-11AT

Faecalibacterium prausnitzii strain AF36-11AT is a Gram-positive, non-motile, rod-shaped bacterium that thrives as an anaerobe, relying on chemoheterotrophic metabolism for energy. This strain is mesophilic, with an optimal growth temperature of 37°C, indicating its adaptation to warm-blooded hosts. F. prausnitzii is known to inhabit a variety of environments, including the gastrointestinal tracts of multiple hosts such as Homo sapiens (humans), Gallus gallus (chickens), Macaca mulatta (rhesus macaques), Macaca fascicularis (long-tailed macaques), and various Metazoa and Aves. This diverse host range suggests a significant ecological role in the gut microbiota of these organisms. The bacterium has a single replicon and is characterized by its non-sporulating nature, which may influence its survival strategies in the gut environment. The presence of flagella is noted, although the non-motility suggests that it does not actively move through its habitat but may rely on other mechanisms for colonization and interaction within the gut microbiome. The ecological significance of F. prausnitzii is underlined by its prevalence in healthy human gut microbiota and its potential role in maintaining gut health. This strain's ability to thrive in various hosts points to its adaptability and importance in microbial communities, possibly contributing to the metabolic processes that promote host well-being and influence overall gut health.
