Blastocystis: view from atop the gut-brain iceberg

Abstract

Blastocystis is a common intestinal parasite that has been linked to gut pathology in humans. In this article, we highlight recent publications that offer insight into how these organisms can influence human cognition and the gut microbiome. We also suggest a potential mechanism of action by which this might occur.

Keywords: Blastocystis; behaviour; gut–brain axis; microbiome; parasite.
