BLASTOCYSTIS HOMINIS-POTENTIAL DIAHORREAL AGENT: A REVIEW

Abstract

Blastocystis hominis is a protozoan intestinal parasite and it has a widespread geographic distribution in countries of all income levels globally. A true pathogenic status of Blastocystis hominis is yet controversial; while it has been found in patients with gastrointestinal symptoms mainly. Moreover, Blastocystis is usually found in people who report no symptoms, and it has been estimated that most cases may be asymptomatic. The plausible reasons could be Blastocystis’ lack of pathogenicity or personal immunity of the host. Research on Blastocystis hominis is scarce with large gaps remaining in complete understanding. In this regard, this review highlights its life cycle, transmission mechanisms, incubation period, epidemiology, and treatment options.
