Spirochaetes have been found in human populations in the developing world but rarely in developed countries except in AIDS patients and homosexuals. No causal links with diet have been established. In some cases these spirochaetes have been linked to human gastrointestinal disturbance and they have been reported to be pathogenic in 1-day-old specific-pathogen-free chicks. There are a large number of isolates of intestinal spirochaetes but only one species so far described in the literature (Brachyspira aalborgi). Future developments are likely to include establishing the involvement of these organisms in disease and elucidating their taxonomy. © Williams & Wilkins 1996. All Rights Reserved.
