title: [Blood digestion and the formation of a plague block in Ceratophyllus tesquorum fleas].
abstract: The fleas of C. tesquorum are characterized by high protease activity in the epithelium and contents of the stomach, quick hemolysis of erythrocytes and low blood coagulation. Rare blockformation in C. tesquorum and its long terms under experimental conditions are apparently associated with changes in the quantity of plague microbes in the digestive tract depending on the stage of blood digestion: reduced during the hemolysis of erythrocytes and increased when it was over.
