Blastocystis cysts were detected in 38% (47/123) (37 Scottish, 17 Malaysian) of sewage treatment works. Fifty percent of influents (29% Scottish, 76% Malaysian) and 28% of effluents (9% Scottish, 60% Malaysian) contained viable cysts. Viable cysts, discharged in effluent, provide further evidence for the potential for waterborne transmission of Blastocystis.
Blastocystis is anaerobic, unicellular protozoan resides in intestinal tract of human as well as other hosts. It was considered as fungus before, now it has been classified to a protozoa. The pathogenicity of the organism is still doubtful and is the subject of debate. Hence, in this review, we will discuss classification, morphology, lifecycle, pathogenicity, Clinical features, Diagnosis and t...

I have read with interest the paper by Kulik et al. published in the fourth issue of 2008 regarding Blastocystis sp. infection in patients with chronic renal disease undergoing hemodialysis [1]. Blastocystis had long been disreg...
Blastocystis is a common zoonotic enteric protozoan that has been classified into 17 distinct subtypes (STs). A cross-sectional study was conducted to determine the prevalence and subtype distributions of Blastocystis in villagers living along the Chao Phraya River, Ayutthaya Province, Thailand, and to assess the risk of zoonotic infection. In total, 220 stool samples were collected, and DNA wa...
Small-subunit (SSU) rRNA gene sequences were obtained by PCR from 12 Blastocystis isolates from humans, rats, and reptiles for which elongation factor 1alpha (EF-1alpha) gene sequences are already available. These new sequences were analyzed by the Bayesian method in a broad phylogeny including, for the first time, all Blastocystis sequences available in the databases. Phylogenetic trees identi...
Blastocystis is an extracellular, enteric pathogen that induces intestinal disorders in a range of hosts including humans. Recent studies have identified potential parasite virulence factors in and host responses to this parasite; however, little is known about Blastocystis-host attachment, which is crucial for colonization and virulence of luminal stages. By utilizing 7 different strains of th...
Blastocystis sp. is a common intestinal parasite infecting humans and a wide range of animals worldwide. It exhibits an extensive genetic diversity and 17 subtypes (STs) have thus far been identified in mammalian and avian hosts. Since several STs are common to humans and animals, it was proposed that a proportion of human infections may result from zoonotic transmission. However, the contribut...
Blastocystis is a genus of common single-celled intestinal parasitic protists with an unsettled role in human health and disease. Being a stable component of intestinal microbiota, once established, the Blastocystis parasite appears more common in healthy individuals than in patients with infectious, functional, or inflammatory bowel disease. Recent data suggest that the parasite is associated ...
Background and purpose: Blastocystis hominis is a common intestinal protozoon with worldwide distribution. The prevalence of this parasite varies between different countries. This study aimed at investigating the prevalence of Blastocystis in individuals attending health centers in Sari, Iran, 2014. Materials and methods: We conducted a descriptive study in which 420 stool samples were obtai...
BACKGROUND Acute diarrhea is one of the major public health problems worldwide. Most of studies on acute diarrhea have been made on infants aged below 5 years and few efforts have been made to identify the etiological agents of acute diarrhea in people over five, especially in China. METHODS 271 diarrhea cases and 149 healthy controls over 5 years were recruited from four participating hospit...
