Faecalibacterium prausnitzii strain 942/30-2

Faecalibacterium prausnitzii strain 942/30-2 is a Gram-positive, non-motile, rod-shaped bacterium that thrives as an anaerobe, relying on chemoheterotrophic metabolism for energy. It is mesophilic, with an optimal growth temperature of 37°C, making it well-suited to the warm environments of the gastrointestinal tracts of various hosts. The strain has been identified in multiple habitats, indicating its ecological versatility and potential roles in different biological systems. F. prausnitzii is associated with a variety of hosts, including Homo sapiens (humans), Gallus gallus (chickens), various Metazoa and Aves, as well as primates such as Macaca mulatta and Macaca fascicularis. This broad host range suggests that the bacterium may play a significant role in gut health and microbial communities across different species, potentially contributing to the maintenance of gut homeostasis and influencing host metabolism. Notably, F. prausnitzii strain 942/30-2 does not form spores, which may indicate a reliance on stable environments for survival. The presence of a single replicon in its genetic structure suggests a streamlined genome, possibly facilitating its adaptation to the gut microbiome. The strain's significance in the gut microbiota is further underscored by its potential role in anti-inflammatory processes, as other strains of F. prausnitzii have been linked to beneficial effects on intestinal health. Thus, understanding this strain may provide insights into its ecological contributions and potential therapeutic applications in gut-related health issues.
