Campylobacter gracilisRANK: SpeciesTAXONOMY: Proteobacteria -> delta/epsilon subdivisions -> Epsilonproteobacteria -> Campylobacterales -> Campylobacteraceae -> Campylobacter -> Campylobacter gracilis OVERVIEW: In 1981, four species were recognized as comprising what had previously been called Bacteroides corrodens. one of these organisms was called Bacteroides gracilis, but based upon 16S rRNA analysis, the organism was transferred to the genus Campylobacter. Campylobacter gracilis is microaerophilic, but is stimulated on media containing formate and fumerate.Campylobacter gracilis is a common member of subgingival plaque. 16S rRNA cloning studies indicate that it is generally the most common oral Campylobacter species identified.Campylobactrer gracilis is a member of Socransky's Orange Complex and is associated with periodontal disease. It has been recoved from primary endodontic infections. It is occasionally isolated from systemic infections.Identified as a constituent of the oral microbiome by Human Oral Microbiome Database. Identified as constituent of vaginal microbiome. [PMID:23282177] 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] |
