This Month in Blastocystis Research (DEC 2015)

by Christen Rune Stensvold in Blastocystis Parasite Blog

Practically all Blastocystis research has focussed on identifying a role for the parasite in disease. Meanwhile, no one has really tried to looked into what Blastocystis may tell us about human health. Together with partner labs, our lab has produced data suggesting that Blastocystis carriage is extremely common, and probably also extremely long lasting. We have also shown that the parasite is associated with certain gut microbial communities and that it is more common in healthy individuals tha........ Read more »

Intestinal Parasites: Friends, Foes and Shades of Gray

by Aurametrix team in Irritable Bowel Blog

Parasite is a bad word with negative connotations. Yet, "bad things" can be good for you - and every situation is different. About one third of people in the world carry at least one parasite in their gastrointestinal tract, and the relationship between health and intestinal parasites is not as straightforward as one might think....

Almost This Or Almost That? Must Be The Other

by Mark Lasbury in As Many Exceptions As Rules

The protists are a catch-all kingdom, neither characteristics nor cladistics can easily group them, or even tell you what one is. Recent studies have begun to identify histories of the plant-like protist phyla based on their flagella. Rhodophyta are a basal phylum, and yet they have no flagella at all, while genomic studies have identified 495 different proteins in chromista flagella, with some being specific to each of the two dissimilar flagella on the organisms. Such diversity within one grou........ Read more »

Proteins and Prejudice—The Mr. Darcy of Protists, Giardia, Defies the Canonical Mitotic Checkpoint Proteins

by John Fleischman in ASCB Post

It is a truth all but universally acknowledged that a eukaryotic cell entering mitosis must be in want of the canonical proteins for mitotic checkpoints. And then there is Giardia intestinalis. A notorious flagellate pathogen, this binucleate protist belongs to one of the major eukaryotic lineages now called the "Excavates." Like all other Excavates, Giardia is weird, says Zacheus Cande of the University of California, Berkeley, but weird in a good way because of its ancient evolutiona........ Read more »
