Human intestinal spirochetosis was described by Harland and Lee in 1971, after observing colonization of the apical membrane of the intestinal mucosa by spirochetes. The clinical importance of these findings is not clear, since it is unknown whether the presence of these microorganisms is pathogenic or commensal. The clinical presentation is variable. It can be asymptomatic or manifest with abdominal pain, changes in intestinal rhythm and rectal bleeding. The prevalence of intestinal spirochaetosis is notably higher in developing countries than in developed countries, with the most likely route of transmission being fecal-oral, although sexual transmission has also been suggested as it is more prevalent in homosexual men. We present the case of a 42-year-old man, in treatment for 3 years with Tenofovir, with an HIV-positive partner, who went to the hospital for persistent diarrhea associated with eating a hamburger.
