Parabacteroides johnsonii DSM 18315

Parabacteroides johnsonii DSM 18315 is a Gram-negative bacterium characterized by its distinct morphological and biochemical traits. This species belongs to the genus Parabacteroides, which encompasses various anaerobic bacteria commonly found in the gastrointestinal tract of mammals. As a member of the gut microbiota, P. johnsonii plays a role in the fermentation of complex carbohydrates, contributing to the overall metabolic processes of the host. The Gram-negative nature of P. johnsonii indicates a specific structural composition of its cell wall, which includes a thin peptidoglycan layer surrounded by an outer membrane containing lipopolysaccharides. This structural feature is significant, as it influences not only the bacterium's interaction with its environment but also its response to antibiotics and other antimicrobial agents. While specific metabolic capabilities and ecological roles of P. johnsonii remain to be fully elucidated, its presence in the gut microbiome suggests potential implications for host health and digestion. The bacterium may participate in the modulation of gut health by aiding in the breakdown of dietary fibers and influencing the overall composition of the microbial community. Further research is necessary to explore the functional roles of P. johnsonii in the gut and its interactions with other microbiota, which may reveal insights into its contributions to host metabolism and immune function.
