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...

Introduction: Blastocystis hominis is a parasite found in the stools of human as well as in the stools of other animals and recently its pathogenic potential has been increasingly recognized. Irritable Bowel Syndrome (IBS) is a digestive system’s disorder which is featured by change in bowel habits, abdominal pains and other symptoms similar to Blastocystis hominis infection. There is lit...

The incidence and prevalence of intestinal parasites in children is most likely due to lack of natural or acquired resistance and differences in behavior and habits closely related to environmental and socioeconomic determinants. The most important protozoa that parasitize humans are Giardia, Entamoeba, Blastocystis, and Cryptosporidium. These parasites present wide intraspecific genetic divers...

The objective of this investigation was to study the morphological characteristics of Blastocystis hominis in sodium acetate-acetic acid-Formalin-preserved stool samples. Routinely processed samples were examined for morphological detail, including size, shape, nuclear detail, and central body characteristics. Morphological findings revealing the importance of recognizing B. hominis in the diag...

Eight hundred stool specimens were examined for the presence of Blastocystis Hominis (BH) by direct microscopy in Saline and Iodine and by concentration with formal saline ether method. Four hundred specimens were positive for Cyst or Ova of various parasites, of which BH was present in 12% samples. Of the total 400 positive cases 56% were positive for Protozoa and within this group 21% were po...

background blastocystis is a common protozoan parasite in mammals, birds, amphibians,reptiles, fish, arthropods, and annelids. this parasite has some subtypes, which pathogenicity status of them still remained controversial. some of blastocystis subtypes are potentially pathogenic to human. objectives this study has identified the b. hominis subtypes and their prevalence rates in hamadan. patie...
