Pentatrichomonas hominis in an immunosuppressed patient with enteric manifestations
Keywords:Diarrhea, Metronidazole, Pentatrichomonas hominis
Pentatrichomonas hominis is a flagellated protozoa considered to be a commensal that inhabits caecum and large intestine in man. It is regarded to be non-pathogenic, however, it has been postulated that these trichomonads undergo multiplication under favorable conditions for growth and exhibit a form of opportunism eventually causing diarrhea. We report, for the first time in India, a case of diarrhea due to P. hominis in an elderly male with myeloid malignancy that resolved on treatment with metronidazole.
