Background P. distasonis and Diseases Services Products Brochures FAQs Resources
Introduction of P. distasonis
Parabacteroides distasonis (P.distasonis) is a member of the gut core microbiome that brings many beneficial properties to its host, in the metabolic, immune, and intestinal inflammation aspects. It could even have the potential to serve as a potential probiotic to promote digestive health in humans based on microbiome or animal studies. Creative Biolabs offers well-established and innovative One-Stop-Shop live biotherapeutic products (LBP) solutions. We are flexible to meet the unique needs of LBP client projects.
Introduction of P. distasonis
P. distasonis is the type of strain for the genus Parabacteroides, a group of gram-negative anaerobic bacteria that commonly colonize the gastrointestinal tract of numerous species. P. distasonis strain has become the strain comparator for all Parabacteroides species. This type of strain is an isolate deposited in 1933 and is a gram-negative, non-spore-forming, rod-shaped, strictly anaerobic bacterium present in the gastrointestinal (GI) tract of humans and animals. A single P. distasonis cell is 0.8-1.6 × 1.2-12 μm in size. Its colonies on sheep blood agar plates are 1-2 mm in diameter, appear gray to off-white, and are circular, slightly convex, and smooth in shape. In intestinal Parabacteroides, P. distasonis is defined as one of the 18 core members of the human intestinal flora and is believed to have important physiological functions in the host. The abundance of P. distasonis is relatively lower in patients with obesity, nonalcoholic fatty liver, and multiple sclerosis.
P. distasonis for Disease Treatment
In a study, oral treatment with live P. distasonis (LPD) reduced weight gain, improved glucose homeostasis, and corrected obesity-related abnormalities, including hyperlipidemia and hepatic steatosis, in both ob/ob mice and high-fat diet (HFD)-induced metabolic syndrome mice. Moreover, the introduction of P. distasonis into obese mice dramatically changed the profile of secondary bile acids. Treatment with P. distasonis also significantly increased intestinal succinate levels, which have recently been identified as an important dicarboxylic acid in maintaining glucose homeostasis. These findings support the gut commensal P. distasonis as a promising probiotic that can modulate host metabolism to alleviate obesity and metabolic dysfunctions.

Scientists reported that oral treatment of BALB/c mice with components from the commensal, P. distasonis, significantly reduces the severity of intestinal inflammation in murine models of acute and chronic colitis induced by dextran sulphate sodium (DSS). The membranous fraction of P. distasonis (mPd) prevented DSS-induced increases in several proinflammatory cytokines, increased mPd-specific serum antibodies, and stabilized the intestinal microbial ecology. These results suggest that specific bacterial components derived from the commensal bacterium, P. distasonis, may be useful in the development of new therapeutic strategies for chronic inflammatory disorders such as IBD.

FAQs
What are the unique properties of P. distasonis that make it a promising next-generation probiotic?
P. distasonis is a gram-negative anaerobic bacterium that colonizes the human gastrointestinal tract. It has shown potential in modulating host metabolism, reducing inflammation, and positively influencing the gut microbiota composition. Its abilities to produce bioactive compounds like succinate and modify bile acid profiles are key factors that contribute to its probiotic properties.
How is P. distasonis cultured and administered in research settings?
P. distasonis is typically cultured under anaerobic conditions in BHI broth. For research purposes, it is administered to animal models through gavage. The culture process involves resuspending the bacteria in BHI broth and ensuring a suitable anaerobic environment for growth.
