Agathobacter rectalis ATCC 33656

Agathobacter rectalis ATCC 33656 is a Gram-positive, rod-shaped bacterium that functions as a chemoheterotroph and thrives in anaerobic environments, with an optimal growth temperature of 37.0°C. As a nonsporulating organism, A. rectalis is adapted to host-associated habitats, suggesting a close relationship with its host, potentially within the gastrointestinal tract. The anaerobic nature of A. rectalis indicates its metabolic processes are optimized for environments devoid of oxygen, which is characteristic of many gut-associated microorganisms. This adaptation allows A. rectalis to play a role in the complex microbial community of the gut, where it may contribute to the fermentation of dietary fibers and other substrates, subsequently impacting host health and metabolism. The presence of A. rectalis in the gut microbiota underscores its potential role in maintaining gut homeostasis and influencing host immune responses. Further insights into its metabolic pathways and interactions with other microbial species could elucidate its contributions to gut health and disease states. Given its specific habitat and energy requirements, A. rectalis may serve as a model organism for studying anaerobic metabolism and microbial ecology in host-associated environments.
