Blood platelets take part in immune reactions of the organism, especially in anti-parasitic immunity. We conducted this study measuring the phagocytic activity of blood platelets. The experiments were done on 35 patients infected G. intestinalis. Diagnosis was supported on finding trophozoits in bile cysts and GSA-65 protein in feces. We have found some decrease of blood platelets count and the increase the percentage of phagocytic platelets. Our general conclusion is, the parasite is able to stimulate the phagocytic activity of blood platelets.
