background: there are some genetic differences in blastocystis that show the existence of species or genotypes. one of these genes that help in identifying blastocystis is ssurrna. the aim of this study was assessment of genetic diver-sity of blastocystis by pcr with seven pairs of sts primers. methods: this study was done on 511 stool samples collected from patients referred to the health care...

Dientamoeba fragilis es un protozoario que parasita el intestino grueso del hombre y animales domésticos. Hasta momento, aún no son claros aspectos de su ciclo vida, como rango hospedadores, reservorios, mecanismo infección, entre otros. Se postula cerdo hospedador natural para este que, debido a cercanía con humano, podría facilitar una transmisión zoonótica. En Colombia existen la fecha estud...

Blastocystis is the most common nonfungal microeukaryote of the human intestinal tract and comprises numerous subtypes (STs), nine of which have been found in humans (ST1 to ST9). While efforts continue to explore the relationship between human health status and subtypes, no consensus regarding subtyping methodology exists. It has been speculated that differences detected in subtype distributio...

The role and function of the granular life cycle stage in Blastocystis sp, remains uncertain despite suggestions being made that the granules are metabolic, reproductive and lipid in nature. This present study aims to understand granular formation by triggering apoptosis in Blastocystis sp. by treating them with metronidazole (MTZ). Blastocystis sp.cultures of 4 sub-types namely 1, 2, 3 and 5 w...

Blastocystis hominis is an intestinal protozoan that is emerging as an important cause of diarrhea in the immunosuppressed population. We report two cases of diarrhea caused by this organism in renal transplant recipients. The infection was diagnosed promptly by careful stool examination and treated successfully with metronidazole. These case report highlights the fact that unusual parasites li...

edigraphic.com Blastocystis hominis is a strict anaerobic protozoan that occurs in the intestine of humans and other mammals (Zierdt, 1991). Recently, phylogenetic analyses of ribosomal RNAs place B. hominis within the straminopiles (Silberman et al., 1996). Its pathogenic role in human beings is still disputed by some investigators (Markell and Udkow, 1986; Miller, 1988). The mechanism by whic...
