This article presents the results of studying the prevalence of echinococcosis among large horned animals in the Samarkand and Surkhandarya regions and hematological blood parameters in animals heavily or weakly infected with echinococcus in the wild. In Samarkand region, 8.8% of cattle were infected with echinococci, and in Surkhandarya region - 14.3%. Decrease in the amount of erythrocytes and hemoglobin in the blood of cattle infected with echinococcosis (20-30%), increase in the number of leukocytes by 30-55%, and a significant increase in the number of eosinophils and lymphocytes in the leukoform, a decrease in neutrophils compared to control (3.25-6.5%). lymphocytes increased by 5.3-15.3%.
