Parabacteroides distasonis ATCC 8503

Parabacteroides distasonis ATCC 8503 is a Gram-positive, anaerobic bacterium characterized by its rod shape and non-motility. It exhibits a mesophilic temperature range, thriving in moderate temperature conditions. This species contains one replicon and possesses two membranes, indicative of its Gram-positive classification. P. distasonis is free-living and does not have any known pathogenicity, which suggests it plays a non-harmful role within its ecological niche. Its inability to form spores indicates a reliance on specific environmental conditions for survival and reproduction. The organism's habitat is host-associated, meaning it is commonly found within the gastrointestinal tracts of various hosts. This association suggests that P. distasonis may contribute to the complex microbial communities in these environments, potentially influencing host health and digestion. Overall, the ecological function of Parabacteroides distasonis ATCC 8503 could be significant in maintaining gut homeostasis, aiding in nutrient absorption, and competing with pathogenic microorganisms. Its role as a free-living, non-pathogenic bacterium highlights the importance of such organisms in promoting a balanced microbiome in host-associated habitats.
