Update on Blastocystis: highlights from the Fourth International Blastocystis Conference

Open Research Europe
While the stramenopile Blastocystis , first discovered in 1911, is considered the most prevalent enteric protist in humans, its biology remains largely unexplored. Clinical studies have only recently begun investigating the role of Blastocystis in the ...

Microbiota characterization in Blastocystis-colonized and Blastocystis-free school-age children from Colombia [PDF]

Parasites & Vectors, 2020
Background Blastocystis is a protist that lives in the intestinal tract of a variety of hosts, including humans. It is still unclear how Blastocystis causes disease, which presents an ongoing challenge for researchers.

Molecular Prevalence and Genetic Diversity of Blastocystis sp. in Slaughtered Ruminants in Qazvin Province, Iran: A Zoonotic Concern. [PDF]

Vet Med Sci
Moderate prevalence of Blastocystis sp. was detected in cattle, sheep and goats (22.5%) in Qazvin Province. Diverse STs (ST1, ST5, ST7, ST10, ST14) were identified, including both ruminant‐adapted and common human‐associated STs. Females showed higher infection rates than males, highlighting potential host‐related risk factors. Presence of zoonotic STs

Prevalence and Genetic Diversity of Blastocystis sp. in Humans, Dogs and Cats in Gabon: A One Health Perspective. [PDF]

Zoonoses Public Health
ABSTRACT Introduction Blastocystis sp. is a cosmopolitan protist that colonises the gastrointestinal tract of mammals, including humans, dogs and cats. Although its pathogenicity remains debated, Blastocystis sp. has been linked to gastrointestinal symptoms and alterations in the gut microbiota.

<i>Blastocystis</i> in a Liver Abscess: An Unusual Extraintestinal Location. [PDF]

Case Rep Infect Dis
Blastocystis is a common anaerobic protist of uncertain pathogenicity that inhabits the human intestine. Rare cases reported in the literature suggest possible extraintestinal dissemination by unclear mechanisms. We followed a 43‐year‐old Peruvian woman presenting with low‐grade fever and gastrointestinal symptoms who was diagnosed with a liver abscess

The Microbiome Within a Microbe: Rethinking Blastocystis Biology. [PDF]

J Eukaryot Microbiol
ABSTRACT Blastocystis spp., one of the most prevalent microeukaryotes in the human gut, has long puzzled researchers with its ambiguous role in health and disease. Decades‐old microscopy studies reported bacterial‐ and viral‐like particles within Blastocystis spp. cells, but these findings have been mainly overlooked.

Stool Microbiota Diversity Analysis of Blastocystis-Positive and Blastocystis-Negative Individuals [PDF]

, 2022
Blastocystis is a unicellular eukaryote found in the gastrointestinal tract of both human and other animal hosts. The clinical significance of colonic Blastocystis colonization remains obscure.

Intestinal shedding of enteric agents in histo-blood group antigen-secretor children in an Australian community-based birth cohort study

Journal of Pediatric and Neonatal Individualized Medicine, 2022
Histo-blood group antigens are inherited polymorphic glycans expressed on mucosal epithelial cell surfaces and shed in secretions. They act as receptors for gastrointestinal pathogens. Those expressing these antigens are categorized as secretors and have

Intestinal immune responses to commensal and pathogenic protozoa

Frontiers in Immunology, 2022
The physical barrier of the intestine and associated mucosal immunity maintains a delicate homeostatic balance between the host and the external environment by regulating immune responses to commensals, as well as functioning as the first line of defense
