SpecialtyInfectious disease

Human intestinal spirochetosis, often called just intestinal spirochetosis when the human context is implicit, is an infection of the colonic-type mucosa with certain species of spirochetal bacteria. Similar infections sometimes occur in pigs, dogs, and birds; porcine intestinal spirochaetosis is an economically important disease of livestock.

Signs and symptoms[edit]

No clear association exists with complaints. However, potential associations include abdominal pain and watery diarrhea, which may be seen with blood; however, these findings are not specific and may be due to a number of other causes.[2]

Cause[edit]

Human intestinal spirochetosis is caused by Brachyspira pilosicoli and Brachyspira aalborgi.[3] Porcine and avian intestinal spirochetosis are caused by Brachyspira hyodysenteriae and Brachyspira pilosicoli.[citation needed]

Diagnosis[edit]

Micrograph showing intestinal spirochetosis. H&E stain.

It is diagnosed by examination of tissue, i.e., biopsy.[citation needed]

Management[edit]

Symptomatic individuals can be treated with oral metronidazole.
