Bacteroides fragilis strain BFR_KZ02

Bacteroides fragilis strain BFR_KZ02 is a Gram-negative, rod-shaped bacterium classified as a chemoorganotroph, utilizing organic compounds for energy. This strain is an anaerobe, thriving in environments devoid of oxygen, and is typically found as single cells rather than in clusters. BFR_KZ02 is mesophilic, with an optimal growth temperature of 37°C, which aligns with the body temperature of its various hosts, including Homo sapiens, Gallus gallus, Metazoa, Equidae, and Serpentes. This strain possesses a unique biotic relationship, as it is free-living yet associated with multiple hosts. Bacteroides fragilis is notable for its pathogenic potential in humans, being implicated in various health issues such as bacteremia, abscess formation, and colorectal cancer. It can contribute to severe conditions like septicemia, intraabdominal abscesses, and soft-tissue infections. The pathogenicity of this strain highlights its role in both health and disease, emphasizing its significance in the human microbiome. BFR_KZ02's structure includes two membranes and a single replicon, characteristic of its classification within the Bacteroides genus. Understanding the ecological role and health implications of Bacteroides fragilis strains like BFR_KZ02 is crucial, as they can influence host health, particularly in the context of intestinal microbiota balance and the potential for opportunistic infections. The bacterium's ability to establish itself in various hosts indicates its adaptability and relevance in microbial ecology.
