Spirochetes that were identified as Brachyspira pilosicoli were present in the ceca of 7.5- to 18-wk-old turkeys with cecal spirochetosis and typhlitis. 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. To the author's knowledge, this is the first report of B. pilosicoli in the ceca of turkeys.
