INTRODUCTION The present study was carried out from March to May 2008, with the aim of evaluating the effectiveness of different techniques for diagnosing Blastocystis hominis in a sample of the population attended at the Biomedicine Laboratory of Feevale University, Novo Hamburgo, Rio Grande do Sul. METHODS On hundred feces samples from children and adults were evaluated. After collection, t...

Blastocystis hominis has long been described as a non pathogenic protozoan parasite until recently when claims have been made that it can result in pathogenic conditions. Of the 729 stool samples (614 from survey and 115 from pediatric wards) examined, 18.1% of them were found to be positive for one or more intestinal protozoan cyst. The commonest was Giardia intestinalis (8.4%) Followed by Ent...

context blastocystis hominis is a unicellular protozoan found commonly in the intestinal tract of humans and many other animals with multiple subtypes, which tend to be specific to the host. we aimed to apply a meta-analysis for studies of protozoan pathogens in order to obtain a general overview of the prevalence and genotype analysis of blastocystis spp. in iran. results we included 40 eligib...

blastocystis hominis is a protozoan parasite which mainly found in human fecal samples both from symptomatic patients and asymptomatic population in developing countries. in this study we reported a patient referred to gi clinic with abdominal pain, nausea, vomiting, fever for 2 or 3 days and passed watery stools because of blastocystis sp. subtype 2 infection.

background: blastocystis  is a zoonotic protozoan parasite habit in intestinal tract of humans and wide range of animals. because of the mysterious nature and unknown or less-known aspects of blastocystis, comprehensive information about epidemiology of this parasite is not available. the objective of this study was to investigate the available parasitology studies during the last decade in ira...

Iron/sulfur cluster (ISC)-containing proteins are essential components of cells. In most eukaryotes, Fe/S clusters are synthesized by the mitochondrial ISC machinery, the cytosolic iron/sulfur assembly system, and, in photosynthetic species, a plastid sulfur-mobilization (SUF) system. Here we show that the anaerobic human protozoan parasite Blastocystis, in addition to possessing ISC and iron/s...

Genomic DNA of Blastocystis isolates released into 0.1% Triton X-100 was suitable for amplification and yielded similar results as the genomic DNA extracted with standard kit. The specific B. hominis primers (BH1: GCT TAT CTG GTT GAT CCT GCC AGT and BH2: TGA TCC TTC CGC AGG TTC ACC TAC A) successfully produced the PCR product of about 1,770 bp with all the 7 Blastocystis isolates tested. The re...
