Blastocystis spp. (spp.) is an unicellular large intestinal protozoan parasite that has a worldwide distribution. It unclear pathogenicity and linked to many clinical disorders. The study purpose was determine the prevalence of molecularly in cohort symptomatic asymptomatic individuals assess association with patient characteristics as possible predictors occurrence Fecal specimens were collect...

background: blastocystis is one of the most common parasites, reported from both human and animals. this parasite is more prevalent in regions with low levels of hygiene, close contact with animal and unsuitable disposal systems. the aim of the study was to subtype blastocystis sp., isolated from diarrheic and non-diarrheic patients using sequencing of 18s ribosomal dna. methods: totally, 300 s...

In regions with high prevalence, Blastocystis hominis is frequently found in association with Entamoeba histolytica/E. dispar in xenic cultures. Its exacerbated growth is often superimposed on the growth of amebas, thus impeding the continuation of the amebas in the culture, within a few generations. The present study reports on the excellent efficacy (100%) of the antifungal agent miconazole i...

The in vitro activities of magainin analogs against Blastocystis hominis, Entamoeba histolytica, and Trypanosoma cruzi were assessed by protozoan morphological integrity and motility. The antiprotozoan activities in descending order were magainin B greater than G greater than H, the same order as the alpha-helix contents of the analogs. Magainin B and G were effective against B. hominis, T. cru...

Metronidazole (MTZ) was the most widely accepted treatment for Blastocystis hominis (B. hominis) with high treatment failure rate, resistance and potential mutagenic and carcinogenic effects so there is urgent need to find out new, effective and safe treatment against B. hominis. The present research aimed to evaluate the therapeutic effect of the aqueous extract of Nigella sativa (NS) at diffe...

Acquisition of mitochondria by the ancestor of all living eukaryotes represented a crucial milestone in the evolution of the eukaryotic cell. Nevertheless, a number of anaerobic unicellular eukaryotes have secondarily discarded certain mitochondrial features, leading to modified organelles such as hydrogenosomes and mitosomes via degenerative evolution. These mitochondrion-derived organelles ha...

Blastocystis is a common intestinal parasite of unsettled clinical significance, which is not easily detected by standard parasitological methods. The genus comprises at least 13 subtypes (STs) (which likely represent separate species), 9 of which have been found in humans. Recent data indicate that at least one of the subtypes is associated with intestinal disease. A quantitative TaqMan 5' nuc...

OBJECTIVES To determine the associated clinical symptoms and prevalence of Blastocystis hominis (B. hominis).  METHODS Stool samples of 50,185 patients (26,784 males and 23,401 females) who were received at the Parasitology Laboratory of Yuzuncu Yil University Faculty of Medicine, Van, Turkey in the last 5 years were inspected microscopically using saline and iodine-stained wet-mount preparat...

This is the first study of seasonal prevalence of parasitic infections over a period of 18 years in an urban/suburban setting anywhere in the world. We examined parasitological test results of 7766 fecal specimens from 3883 patients in the Los Angeles County, from 1996 to 2013 tested at Parasitology Center, Inc. (PCI), Scottsdale, Arizona. During this period, 1629 (41%) of patients were found i...
