Bacteroides fragilis strain 12905

Bacteroides fragilis strain 12905 is a Gram-negative, rod-shaped bacterium that typically exists as single cells and thrives optimally at a temperature of 37.0 °C. As a chemoorganotroph, this strain derives its energy from organic compounds, indicating its reliance on a rich organic environment for growth and metabolism. This microbe is classified as an anaerobe, meaning it grows in environments devoid of oxygen, which aligns with its habitat as a host-associated organism. Bacteroides fragilis strains, including 12905, are commonly found in the gastrointestinal tracts of humans and other animals, where they play a crucial role in the digestion of complex carbohydrates and the maintenance of gut homeostasis. The unique ecological role of Bacteroides fragilis strain 12905 extends beyond simple digestion; it is involved in the modulation of the host's immune response and contributes to the overall microbial diversity within the gut ecosystem. This bacterium exemplifies the intricate relationships between host organisms and their associated microbiota, highlighting its potential significance in both health and disease contexts.
