TESTING OF NATURAL-POPULATIONS OF CRUSTAC EA AND MOLLUSCA FOR INFECTION WITH PARASITES USING CELLS OF HEMOLYMPH AND HEMATOPOIETIC TISSUES

In the work intact and infected with parasites cells of hemolimph and of hemopoietic tissues from Biomphalaria sudanica, Planorbis planorbis (Gastropoda, Mollusca) and Gammarus oceanicus (Crustacea Amphipoda) w ere characterized by authoradiographical methods ([H3]timidin-labellin g). It is shown that hemolimph cells are generated by intensively divi ding cell-prescusors concentrated in hemopoietic tissue. In mollusks t his tissue is located in pericardium while in crustaceans it is concen trated in submucosa of stomach. Hemopoiesis activation takes place aft er the studied species are infected with parasites. Hemopoietic organs expend and cell division grows. Authors consider a possibility of usi ng hematological analysis in parasitology.
