Bacteroides fragilis strain OM04-9BH

Bacteroides fragilis strain OM04-9BH is a Gram-negative, rod-shaped anaerobe that thrives in host-associated environments. This strain is classified as a chemoorganotroph, deriving energy from organic compounds, and exhibits a mesophilic temperature range with an optimal growth temperature of 37°C. Importantly, this bacterium is non-motile and is characterized by its single-cell arrangement and the presence of two membranes, with one replicon in its genome. This strain has been identified in various hosts, including Homo sapiens (humans), Gallus gallus (chickens), Metazoa (multicellular animals), Equidae (horses), and Serpentes (snakes). Its biotic relationship is categorized as free-living, indicating its ability to survive independently within these hosts. Bacteroides fragilis strain OM04-9BH is notable for its pathogenicity in humans, where it is associated with a range of health issues including bacteremia, abscesses, colitis, and colorectal cancer. The strain's ability to cause anaerobic bacteremia and local tissue infections highlights its potential impact on human health, particularly in immunocompromised individuals or those with underlying conditions. Ecologically, this strain plays a significant role in the microbiota of various hosts, contributing to the complex interactions within their respective ecosystems. Its pathogenic potential and association with diverse hosts underscore its importance in both health and disease contexts, reflecting the intricate balance between microbial inhabitants and their hosts.
