In January 2005, a survey of intestinal parasitic infections was performed in a primary school, central Thailand. Of 675 stool samples, Blastocystis was identified with a prevalence of 18.9%. Genetic characterization of Blastocystis showed subtype 1 (77.9%) and subtype 2 (22.1%). Study of the water supply in this school was performed to find the possible sources of Blastocystis. Blastocystis fr...

materials and methods random sampling was carried out from january to may 2012. one hundred and forty fecal samples from stray cats were examined using sucrose flotation method. results gastrointestinal parasites were found in 121 of the 140 (86.4%) examined samples. the parasites detected in stray cats were toxocara spp. (45%, 63/140), isospora spp. (21.4%, 30/140), nematode larvae (21.4%, 30/...

BACKGROUND This study compared diagnostic methods for identifying Blastocystis in stool samples, and evaluated the frequency of detection of Blastocystis in patients with irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). RESULTS AND DISCUSSION From a set of 105 stool specimens submitted for routine parasitological analysis, 30 were identified as positive for Blastocystis by...

Blastocystis is a ubiquitous enteric protozoan found in the intestinal tracts of humans and a wide range of animals. Evidence accumulated over the last decade suggests association of Blastocystis with gastrointestinal disorders involving diarrhea, abdominal pain, constipation, nausea, and fatigue. Clinical and experimental studies have associated Blastocystis with intestinal inflammation, and i...

Blastocystis is an ubiquitous, enteric protozoan of humans and many other species. Human infection has been associated with gastrointestinal disease such as irritable bowel syndrome, however, this remains unproven. A relevant animal model is needed to investigate the pathogenesis/pathogenicity of Blastocystis. We concluded previously that pigs are likely natural hosts of Blastocystis with a pot...

163 The first identification of Blastocystis dates back to more than 100 years even though the scientific knowledge acquired during this period to understand the taxonomy, biology, and pathogenic capabilities of Blastocystis is not entirely convincing. However, in recent decades, the studies focusing on pathogenicity and taxonomy of Blastocystis have taken up the speed. The editors Dr. Heinz Me...

Blastocystis is a polymorphic intestinal parasite that is common in humans. A total of 51 asymptomatic and symptomatic patients positive for Blastocystis only were included in the study. Symptoms were mainly nonspecific gastrointestinal symptoms. Blastocystis isolates were xenically cultured and subtyped. Blastocystis species subtype 3 was the predominant subtype. Intrasubtype differences (vacu...

Monkeys are important experimental models for investigating human diseases. The aim of this study was to survey the alimentary tract parasites among imported vervet monkeys (Cercopithecus aethiops) to Iran. Fecal samples were collected from 40 vervets imported from Tanzania to Razi Vaccine and Serum Research Institute of Iran. Fecal samples were assessed by direct smear and Telman sedimentation...

In the tropics, there are too few studies on isolation of Blastocystis sp. subtypes from water sources; in addition, there is also an absence of reported studies on the occurrence of Blastocystis sp. subtypes in water during different seasons. Therefore, this study was aimed to determine the occurrence of Blastocystis sp. subtypes in river water and other water sources that drained aboriginal v...
