Title: DIROFILARIASIS AND HEMOBARTONELLOSIS IN DOGS IN VYBORG OF LENINGRAD REGION
Abstract: The article is devoted to determining the spread of dirofilariasis in the Vyborgsky district of the Leningrad region. The objects of the study were 23 dogs of various breeds aged from 1 to 9 years. Of these, 21 dogs were in a shelter, and 2 dogs were kept at home. As part of routine research, diagnostics was carried out for 10 types of helminths. 4 dogs were identified, in the blood of which antibodies to dirofilariasis were detected by PCR. In 100% of cases, the causative agent is Dirofilaria repens. The average invasion intensity (EI) of D. repens (Railliet et Henry, 1911) was 17.4%. By PCR, hemobartonellosis was detected in 6 dogs (28.6%), and in 9.5% of the animals mixed invasion was observed - hemobartonellosis and dirofilariasis. Thus, on the territory of the Vyborgsky district of the Leningrad region, a local focus of dirofilariasis and hemobartonellosis of carnivores is actively functioning, in the spread of which stray and owner dogs are actively involved, which indicates the circulation of parasites in the study area and the possibility of infection of other animals and humans. For the implementation of effective prevention of dirofilariasis, we suggest using drugs based on macrocyclic lactones, and hemobartonellosis - doxycycline.
