Classification of Parabacteroides distasonis and other Bacteroidetes using O- antigen virulence gene: RfbA -Typing and hypothesis for pathogenic vs. probiotic strain differentiation

Abstract excerpt

Parabacteroides distasonis (Pdis) is the type species for the new Parabacteroides genus, and a gut commensal of the Bacteroidetes phylum. Emerging reports (primarily based on reference strain/ATCC-8503) concerningly propose that long-known opportunistic pathogen Pdis is a probiotic. We posit there is an urgent need to characterize the pathogenicity of Pdis strain-strain variability. Unfortunately, no...
