초록

Dirofilariasis is a mosquito-borne parasitic infection that mainly causes symptoms such as chronic cough, respiratory distress, abnormal breath sounds, heart valve dysfunction, right heart hypertrophy, liver congestion and cirrhosis, ascites, and pleural effusion in dogs. In this study, from June to September 2021, we collected and identified mosquitoes in parks where citizens often take their dogs for a walk, and created pools from them by month, species, and location. These pools were checked for the infection of Dirofilaria immitis by PCR and the minimum infection rates (MIRs) were calculated. The MIR of all mosquitoes collected was 6.4, and the MIRs of mosquitoes from Daewangam Park, Yeocheoncheon Walk, Taehwagang National Garden, and Sinbulsan County Park were 9.7, 4.7, 2.1, and 0, respectively. It also confirmed that Aedes hatorii, Aedes vexans nipponii, and Ochlerotatus koreicus were major vectors of heartworm in Ulsan. Our results suggest that heartworm prophylaxis should be considered in Ulsan.
