Bacteroides thetaiotaomicron

Bacteroides thetaiotaomicron is a Gram-negative, rod-shaped bacterium that is classified as an anaerobe, thriving in environments devoid of oxygen. This microbe possesses a unique cellular structure, characterized by two membranes and true flagella, although it does not exhibit motility. The species is mesophilic, indicating its optimal growth occurs at moderate temperatures. Bacteroides thetaiotaomicron is primarily host-associated, engaging in a free-living biotic relationship. It has three replicons, suggesting a complex genomic architecture that may contribute to its adaptability and functional diversity. The genome accessions available for this species include QRUV00000000.1, CZAP00000000.1, and CZBI00000000.1, which can provide further insights into its genetic makeup and potential functionalities. Notably, Bacteroides thetaiotaomicron is integral to the gastrointestinal microbiota of many hosts, playing a crucial role in the degradation of complex carbohydrates. This capability highlights its importance in nutrient metabolism and host health, suggesting that it may influence digestive processes and the overall homeostasis of the gut ecosystem.
