Abstract
New data were obtained when studying the effect of intensive dirofilariоsis invasion on the morphological composition of the blood corpus of infected dogs. Hematological studies were performed on 20 dogs infected intensively with microfilaria. Blood from dogs was taken from a forearm vein in test tubes with an anticoagulant. For research, 2 groups were formed: experimental and control. The experimental group (n=10) consisted of dogs that had microfilaria dirofilariasis in blood samples. The control group of dogs (n=10) was formed from agelminthous animals, in the blood of which there were no nematode microfilaria. Results. With intensive invasion of dirofilariоsis in blood samples of dogs, a decrease in the number of erythrocytes is observed by 3.03х1012/l, a decrease in hemoglobin concentration by 70.68 g/l. At the same time, the number of leukocytes in the hematological profile of experienced dogs increased by 14.68х109/l, and that of eosinophils by 497.44%, which indicates profound pathophysiological changes in the hematocrit. Conclusion With a high intensity of dirofilariasis in dogs, erythropenia, hypohemoglobinemia, leukocytosis, and eosinophilia appear strongly on the background of control.
