Researchers studying Blastocystis prevalence and transmission in Calarca’ Columbia report that children in public daycare environments have a high rate of Blastocystis infection, measured at 57.5%. While both Blastocystis-positive and Blastocystis-negative children reported a high rate of diarrhea, children with Blastocystis reported a significantly increased rate (45% vs. 33%, p < 0.05). Blastocystis infection was correlated with the presence of Blastocystis in a sugar cane beverage, drinks other than bottled milk, and foods. The study was published in Biomedia.
