This study was attempted to survey on the prevalence of canine heartworm infection (Dirofilaria immitis) in the Incheon area in 2006. This study showed comparative infection rates of canine heartworm in conjunction with different geographic locations and rearing environments (i.e., indoor, outdoor or free roaming). In total, 24 dogs (6.0%) were D. immitis positive among a total of 400 tested dogs. The geographic distribution of detection rates was Nam-gu (2 dogs, 6.7%), Yeonsu-gu (1 dog, 3.0%), Namdonggu (5 dogs, 8.0%), Pupyoung-gu (4 dogs, 6.7%), Kanghwa-gun (8 dogs, 13.0%), and Onjin-gun (4 dogs, 11.1%). In addition, 4 dogs (2.0%) or 20 dogs (10.0%) were positive for D. immitis among 202 indoor dogs or 198 outdoor dogs including free roaming dogs, respectively, while 13 dogs (11.7%) were positive for D. immitis among 111 outdoor dogs excluding free roaming dogs. In the case of 87 free roaming dogs, 7 dogs (8.1%) among them were positive for D. immitis.

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.

전국 5개 지역에서 사육되고 있는 German shepherd종 개 127두(암컷 56. 수컷 71두)를 대상으로 필라리아자충검사법(modified Knott's test)과 성충항원검사법($DiroCHEK^{\circledR}$, Synbiotics. USA)을 이용하여 1994년 10월부터 1995년 8월 사이에 개심장사상충 감염률을 조사하였다. 필라리아자충 검사법에 의한 감염률은 10.2%(13/127)였으나 항원검사법에 의해서는 28.3%(36/127)를 보여 항원 양성견 36두 중 말초혈액에서 필라리아자충이 검출된 경우는 33.3%에 불과하였다 필라리아자충이 검출된 개들은 모두 항원양성반응을 보였다. 항원양성반응 을 보였으나 필라리아자충이 검출되지 않은 은폐감염견들 중 3두를 부검한 결과 심장과 폐동맥에 4-15마리의 개심장사상충 성충이 존재하여 항원검사법이 보다 정확한 검사법임을 시사하였다. 항 원검사법에 의한 지역별 감염률에 있어서는 강원도 횡성지역의 개들이 가장 높았으며(84.4%). 예 천과 중원지역은 20.0%와 14.3%로 각각 조사되었고 김해와 광주지역의 개들에서는 검출되지 알았다. 감염견들의 연령은 1-3세, 4-6세, 그리고 7-11세에서 6.3%. 21.4% 및 56.4%로 각각 조 사되어 연령이 증가함에 따라 감염률도 증가하였다 이 연구의 결과 국내 개심장사상충의 감염률은 필라리아자충검사법에 의한 과거 조사(3.1~23.0%)에 비해 성충항원검사법에 의한 것이 보다 높을 것으로 추정 되었다.

3세 수컷 풍산견이 2주동안 지속된 좌측후지 파행과 식욕저하로 내원하였다. 환자의 외상 병력은 없었으며, 백신과 심장사상충 예방은 하지 않았다. 전혈구검사에서 중증의 백혈구 증가증과 호중구 핵좌방이동이 확인되었고, 혈액화학검사에서 저알부민혈증, 질소혈증, 간담도계 효소수치의 상승을 확인되었으며, 심장사상충 항원 키트에서 양성으로 확인되었다. 흉부 방사선 검사에서는 주폐동맥의 확장, 우심비대, 폐의 간질패턴이 관찰되었으며, 심장사상충 감염소견과 일치하였다. 이후 실시된 심초음파 검사에서 페동맥판역류와 폐성 고혈압이 확인되었다. 선택적 대퇴동맥 혈관 조영술에서 양측성 대퇴동맥의 폐쇄가 확인되었고, 환자는 혈관조영술후 폐사하였고 부검이 실시되었다. 부검결과 심장사상충 성충과 혈전이 좌우측 대퇴동맥 내강을 폐쇄시키고 있는 것이 확인되었다. 본 증례보고는 심장사상충이 대퇴동맥으로 비정상적 이주를 하여 후지의 파행을 유발한 케이스이며, 이를 보고하고자 한다.

Ten dogs were enrolled in this study: two healthy dogs, two obese dogs without other medical issues and six obese dogs with underlying diseases including pemphigus, chronic active hepatitis, hyperadrenocorticism, narcolepsy, otitis media and heartworm infection. Pyrosequencing of the 16S rRNA gene to explore the gut bacterial diversity revealed that distal gut bacterial communities of samples from patients with pemphigus, otitis media and narcolepsy consisted primarily of Firmicutes, while the major phylum of the distal gut bacterial communities in patients with chronic active hepatitis and hyperadrenocorticism was Fusobacteria. Proteobacteria were the dominant phylum in heartworm infected obese patients.

A 4 year old mixed female dog was presented dyspnea, anorexia and syncope. In blood smear test, a lot of heartworm larvae were observed. In thoracic radiography, "reverse D" shape was observed. So, this case was considered with heartworm disease. In echocardiography, marked left heart hypertrophy was presented. In M-mode view, aortic valvular stenosis was found. After mongrel dog died, aortic valvular stenosis was reconfirmed in necropsy. After all, the dog died of pulmonary edema because of aortic valvular stenosis caused left heart failure.t failure.

The prevalence of canine heartworm(Dirofilaria immitis) infection in 150 mixed-breed dogs(male : 54, female : 96) from February to December 1997 was investigated by using antigen test kit(ICT $GOLD^{TM}$ HW, Synbiotics, USA) based on immunochromatographic assay in Inchon city. Also, gross and histopathological findings of an antigen positive dog were carried out. The results were summarized as follows ; 1. Four dogs were positive from 150 tested dogs(2.7%). They were all more than 2 years old and infection rates in male and outdoor dogs was higher than those in female and indoor, respectively. Species of infected dogs were Pug(2) , German Sheperd(1) and Great-dane (1). 2. Regional infection rates were closely related with housing system in the city. 3. Pathological findings of antigen-positive dog was excessive enlargement, congestion and hemorrhage of lung and D immitis in heart and histologically hemosiderin, hypertrophy of pulmonary alveoli wall and irregular hypertrophy of pulmonary artery inner wall. Microfilaria was observed in pulmonary artery and arteriole, ventricle and splenic artery.
