Abstract

An analysis of the results of pathological autopsy of 96 dogs was performed during the study of the epizootic situation of dog heartworm disease in Kyiv. The statistics of 2017-2020 were analyzed and the intensity of the invasion was established, which decreased from 29.6 % to 5.7 % every year, which is due to drier conditions and better treatment of animals. With age, the animals became ill more often, the detection rate of Dirofilaria immitis increased, so in 7-9 year old dogs it was - 36.8 %, in 10-12 year olds – 60 %. German shepherds, half-breeds and purebred dogs were more often ill with yard use - 18.2 %. Pathological and anatomical autopsy of dog carcasses revealed changes characteristic of heartworm disease: the presence of parasites in the lumen of the right ventricle, aorta and pulmonary artery – 100 %; in the lungs (hyperemia and pulmonary edema, pneumonia, aneurysms and thrombosis of the pulmonary artery) up to – 75 %; in the heart (myocardial infarction, pericarditis, endocarditis, myocarditis) – 50 %; in the digestive tract gastro-enteritis (catarrhal, catarrhal-hemorrhagic, hemorrhagic) – 75 %. Own research has established the infestation of dogs with parasites, and the similarity of pathological and anatomical changes in the dissection of animals depending on age, breed and economic use
