  • B. pilosicoli attaches in an end-on manner to the mucosal epithelium of the large intestine and interferes with water absorption in the GI tract. (wikipedia.org)
  • However, the higher prevalence of colonization with B. pilosicoli in humans than dogs suggested that the dogs were infected with human isolates, probably through consumption of human feces ( 8 ). (cdc.gov)
  • The identity of B. pilosicoli was confirmed on the basis of ultrastructural morphology of the cecal epithelium adherent microbes, immunohistochemical staining with a Brachyspira genus-specific monoclonal antibody, and amplification of a B. pilosicoli species-specific 16S ribosomal RNA (rrs gene) sequence by using the polymerase chain reaction and DNA obtained by laser-capture microdissection of the epithelium-adherent microbial fringe.
