Parasites regulate host immune response via secretion of soluble mediators which interact in a certain way with cells and molecules of the immune system. The aim of the study was to determine changes of prostaglandins E2 и D2 content in Dibothriochephallus dendriticus plerocercoids and also in the incubation media during incubation of tapeworms with addition of blood serum from the intermediate host – Baikal cisco. D. dendriticus plerocercoids were retrieved from the host body cavity, ashed in the physiological solution and placed in incubation media. Microcolumn high-performance liquid chromatography was used to detect prostaglandins. Concentration of prostaglandins in the plerocercoid organism increased insignificantly after incubation in the Hanks’ solution with addition of blood serum, when compared with incubation in the Hanks’ solution only. Concentration of prostaglandin E2 increased significantly in the incubation media after incubation of plerocercoids in the Hanks’ solution with addition of blood serum. Prostaglandin D2 was also identified in high concentrations after 12 h and 24 h of incubation, whereas prostaglandin D2 was not quite detected during incubation in Hanks’ solution only.
