Studies from University of Victoria Yield New Data on Blastocystis (The Effect of Blastocystis Sp. and Dientamoeba Fragilis On Psychological Symptom Severity In a Sample of Clinically Diverse Males and Females).

This article focuses on research from the University of Victoria in Melbourne, Australia, examining the effects of the protozoa Blastocystis sp. and Dientamoeba fragilis on psychological symptom severity. The study found no significant impact of these protozoan carriers on symptoms of depression, neurocognitive function, stress, anxiety, sleep, or fatigue in either males or females, despite a higher prevalence of D. fragilis in females. The findings support the view that Blastocystis sp. and D. fragilis may be commensal members of the gut microbiota rather than pathogenic organisms. The researchers emphasize the need for further investigation into the role of protozoa within the brain-gut-microbiota axis.
