We undertook a retrospective analysis of colonic spirochetosis in 14 cases: females, 3; males, 11; children, 4; adults, 10. Two men had HIV infections. All children and both HIV-infected men had abdominal complaints, diarrhea, or both. Most other adults underwent colonoscopy for polyp screening (n = 4) or follow-up of Crohn disease (n = 1) or had other indications (n = 2) or diarrhea (n = 1). H...

Avian intestinal spirochaetosis (AIS) is a condition arising from colonization of the caeca and colon of birds with anaerobic spirochaetes of the genus Brchyspira. The purpose of the present study was to evaluate PCR amplification from formalin-fixed, paraffin-embedded tissue method for detecting infected laying hens with Brachyspira pilosicoli  with the same primers that have been used for det...
