Campylobacter concisus and inflammatory bowel disease

Table 2 Genetic relatedness of enteric and oral Campylobacter concisus strains

Enteric C. concisus strains from patients with IBD	Genetically related C. concisus strains
A strain isolated from intestinal biopsies of patient No. 1	An oral strain from patient No. 6
A strain isolated from intestinal biopsies of patient No. 3	An oral strain from patient No. 3 (identical)
A strain isolated from luminal fluid of patient No. 3	An oral strain from healthy No. 1

Data shown in this table were obtained from reference 13. The genetic relatedness was assessed based on the sequences of six housekeeping genes. These data provide evidence showing that Campylobacter concisus (C. concisus) strains colonizing the intestinal tract of patients with IBD originating from either the patient’s own oral C. concisus strains or oral C. concisus strains from other individuals. IBD: Inflammatory bowel disease.
