Bacteroides ovatusRANK: SpeciesTAXONOMY: Bacteroidetes/Chlorobi group -> Bacteroidetes -> Bacteroidia -> Bacteroidales -> Bacteroidaceae -> Bacteroides -> Bacteroides ovatus OVERVIEW: Bacteroides ovatus as the Predominant Commensal Intestinal Microbe Causing a Systemic Antibody Response in Inflammatory Bowel Disease. 'Our results therefore suggest that B. ovatus is so highly antigenic that it surpasses the anti-inflammatory regulation exerted by an IgA response and thus can cause an inflammatory IgG response too. On the other hand, B. vulgatus does not appear to be sufficiently pathogenic to induce an IgG response in addition to an IgA response.'

[PMID:23282177] In a study of gut bacteria of 15 patients with SARS-CoV-2 over the course of hospitalization, Bacteroides dorei, Bacteroides thetaiotaomicron, Bacteroides massiliensis, and Bacteroides ovatus, which downregulate expression of ACE2 in murine gut, correlated inversely with SARS-CoV-2 load in fecal samples from patients. [PMID: 32442562] [PMCID: PMC7237927] This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072] |
