Parabacteroides distasonis

Parabacteroides distasonis is a Gram-positive, non-motile, rod-shaped bacterium characterized by its anaerobic metabolism and mesophilic temperature classification. This microbe is notable for its structure, possessing two cellular membranes and lacking the ability to form spores. Parabacteroides distasonis is typically found in host-associated environments, suggesting its potential role in the microbiome of various organisms. As a free-living bacterium, it exhibits complex genomic characteristics, with a total of 11 replicons identified across multiple genome accessions. This genetic diversity may contribute to its adaptability in anaerobic habitats. The absence of flagella indicates that P. distasonis relies on other mechanisms for movement within its environment, though its exact motility strategies remain undefined. The ecological role of Parabacteroides distasonis may encompass interactions with host organisms, potentially influencing gut health and contributing to the balance of microbiota. The presence of this bacterium in the gut microbiome could play a significant role in metabolic processes, underscoring its importance in maintaining microbial diversity and functionality in anaerobic environments.
