REVIEW ON PENTATRICHOMONAS HOMINIS (DAVAINE, 1860) SENSU WENRICH, 1931 (TRICHOMONADIDA: TRICHOMONADIDAE) Vladimir Stolzenberg Torres

Abstract

This study addresses Trichomonads, a group of flagellated protozoa found in the genitourinary and gastrointestinal tracts of different hosts. Among them, Pentatrichomonas hominis stands out, considered commensal and found in humans, dogs, cats and other species. Although previously considered non-pathogenic, its presence has been linked to inflammatory bowel diseases, rheumatoid arthritis and even cancer. The prevalence of infection is high, especially in tropical and subtropical regions. Infection occurs via the feco-oral route, with consequent colonization of the large intestine. Although it usually causes self-limiting diarrhea, it can lead to serious complications, especially in children and immunocompromised patients. Diagnosis is made by parasitological examination and molecular analysis, and treatment consists of metronidazole, with dietary changes in mild cases. The study also addresses the morphology and reproduction of P. hominis, as well as methods for diagnosing and controlling the infection. A correct understanding of this species is crucial for the appropriate treatment of Trichomonad infections.
