Intestinal spirochetosis (IS) is a zoonotic and rare gastrointestinal infection caused by Brachyspira. It does not show specific symptoms and are various ; gastrointestinal bleeding, diarrhea, asymptomatic. There is no established consensus for treatment yet. We report a case of a 48-year-old Japanese female with recurred IS and treatment with metronidazole seemed to be effective. She had visited our hospital because of mucus and bloody stool in 2010. A blood test, stool culture, colonoscopy examination had been done and diagnosed with IS. The symptom subsided with no therapy a few days, so we had not tried medication. The next year the symptom had reoccurred and disappeared a few days, so she did not come our hospital. However she showed the same symptom and visited our hospital again in 2014.
We diagnosed that she was suffered from IS and treated her with metronidazole (1,000mg/day for 10days) and her clinical symptom completely improved. This case report suggests that metronidazole treatment for IS infection was effective to prevent recurrence.
