Parabacteroides distasonis strain AM33-1

Parabacteroides distasonis strain AM33-1 is a Gram-positive, anaerobic bacterium characterized by its rod shape and the presence of flagella. This strain is part of the diverse microbiota associated with Homo sapiens, indicating its role in the human gut ecosystem. P. distasonis strain AM33-1 is nonsporulating and free-living, suggesting that it does not form spores to survive unfavorable conditions but rather thrives in the anaerobic environments typical of the human gastrointestinal tract. This bacterium operates within a mesophilic temperature range, which is optimal for growth in the human body, further supporting its adaptation to a host-associated habitat. It possesses a unique cellular structure with two membranes and a single replicon, which is characteristic of certain Gram-positive bacteria. The ecological insight into P. distasonis strain AM33-1 lies in its potential contributions to human health. As a member of the gut microbiota, it may play a role in digestion, metabolism, and the maintenance of gut homeostasis. The presence of flagella may suggest a capability for movement within the gut environment, potentially influencing its interactions with other microbial species and the host's immune system. The accession number QSIP00000000.1 provides a pathway for researchers to access further genomic data on this strain, enhancing our understanding of its biological functions and ecological roles within the human microbiome.
