Diroflliariasis of service dogs in Ararat region of the republic of Armenia

Abstract

For domestic dog breeding, this issue is relevant, since annually dog-hunting trips are carried out to the southern regions of the country, which contributes to the spread of pathogens of dirofilariasis. In the Nizhny Novgorod Region, at the opening of two corpses of service dogs arriving from Chechnya, dirofilaria were found in the heart and pulmonary arteries. In order to diagnose dirofilariasis, the blood of 86 service dogs from the Zonal Center for Cynological Service of the Nizhny Novgorod Region was examined. Identified 11 dogs infected with dirofilaria. In addition, dirofilaria infection was observed in dogs that arrived for training from the North Caucasus region. The movement of dogs from one region to another leads to the creation of new foci of dirofilariasis and, thereby, increases the risk of this invasion in humans. The relevance of dirofilariasis for dog breeding is due to the lack of knowledge of this issue in the Ararat region of the Republic of Armenia, as well as to difficulties in therapy: effective imported medicines are inaccessible due to their high cost, and the arsenal of domestic analogues is small. The article presents materials on the cases of dogs from dirofilariasis in farms of the Ararat region. According to the results of autopsy of dead dogs, as well as studies of venous blood samples of German Shepherd dogs for microfilariae, parasitism of nematodes Dirofilaria immitis Leidy, 1856 with an average intensity of dirofilariasis (EI) in the dog population of Ararat region was found to be 29.6%. It was established that the spread of invasion is uniform. According to the results of examinations in the farms of the Ararat region, therapeutic treatments of dogs against dirofilarosis with Helmimax and Inspector Total S were carried out, as well as a set of preventive measures.
