Controversy surrounds the clinical consequences of infection with this organism: Some researchers strongly believe B. hominis is pathogenic, others believe it is not responsible for clinical symptoms when detected, and still others believe the question of pathogenicity is unsettled [1-5]. We report a case of hemorrhagic proctosigmoiditis believed to be caused by B. hominis infection.A 76-year-old man presented with generalized abdominal cramps, grossly bloody diarrhea, tenesmus, and fecal urgency that had lasted 24 hours. The patient did not have a fever. He had ...References1. Vannatta JB, Adamson D, Mullican K. Blastocystis hominis infection presenting as recurrent diarrhea. Ann Intern Med. 1985; 102:495-6.
