Abstract

Objective: Several non pathogenic protozoa inhabit the intestinal. The non pathogenic protozoa can be divided into two groups: amebae and flagellates. Protozoa are a diverse group of unicellulareukaryotic organisms, many of which are motile. They are restricted to moist or aquatic habitats. That can be flagellates, ciliates, and amoebas (motile by means of pseudopodia).

Methods: All protozoa digest their food in stomach-like compartments called vacuoles. Some protozoa have life stages alternating between proliferative stages (e. g., trophozoites) and dormant cysts. Protozoa can reproduce by binary fission or multiple fission. Some protozoa reproduce sexually, some asexually, while some use a combination, (e. g., Coccidia). Entamoeba is a genus of Amoebozoa found as internal parasites or commensals of animals. Several species are found in humans.

Results: Entamoebahistolytica is the pathogen responsible for 'amoebiasis' (which includes amoebic dysentery and amoebic liver abscesses), while others such as Entamoeba coli and E. dispar are harmless. With the exception of Entamoebagingivalis, which lives in the mouth, and E. moshkovskii, which is frequently isolated from river and lake sediments, all Entamoeba species are found in the intestines of the animals they infect. GenusEntamoebacontains many species, (Entamoebahistolytica, Entamoebadispar, Entamoebamoshkovskii,Entamoebapolecki, Entamoeba coli and Entamoebahartmanni) reside in the human intestinal lumen The nonpathogenic flagellates include Trichomonashominis, Chilomastixmesnili, Trichomonastenax.

Conclusion: The perfect diagnosis for non pathogenic protozoa is very important do not mistake with pathogenic protozoa which need accurate treatment to take the patient to full care.
