A dog which Showed dry muzzle, coughing, dyspnea, weight loss and exercise intolerance was clinically examined. Dirofilaria immitis infection was determined by hematological findings, radiographic evaluation and detection of microfilaria with modified Kno

Two Jindo dogs which show clinical signs of anorexia, weakness and exercise intolerance, were referred, and diagnosed as dirofilariasis by hematology, blood chemistry and ultrasonography. In hematology and blood chemistry, the presence of microfilariae in the blood, anemia, leukocytosis, hemoglobinuria and jaundice were revealed. In ultrasonography, heartworms were found in the right ventricle artery and pulmonary artery as structures of hyperechoic dots or streaks. In autopsy, forty odd and fifty odd of heartworms at dog 1 and dog 2, were ascertained respectively in the right ventricle and pulmonary artery.

Hematologic values were determined in blood samples obtained from 203 normal, healthy Jindo dogs of both sexes that ranged in age from 3 months to 10 years. Age-related differences were detected for the total erythrocyte count, hemoglobin content, PCV and the number of eosinophils. The persistent eosinophilia appears to be due to the dirofilariasis and flea-allergy dermatitis.

This study was conducted to survey Dirofilaria (D.) immitis antigen, and Anaplasma (A.) phagocytophilum, Borrelia (B.) burgdorferi, and Ehrlichia (E.) canis antibodies among clinically healthy dogs in the Daejeon city and Kangwon province. Whole blood samples were collected from two hundred and fifty two dogs (127 females and 125 males, 147 outdoors and 105 indoors), and they were tested by using ELISA kit (SNAP 4Dx, IDEXX Laboratories, USA). Chi-squared analysis showed that A. phagocytophilum of female dogs in outdoors group was significantly higher prevalence than that of female dogs in indoors group (p < 0.05). In addition, infection rate of A. phagocytophilum of over 7 year-old-dogs in outdoors group revealed significantly higher prevalence than that of indoors group (p < 0.01). In E. canis, the under 4 year-old-dogs (p < 0.05), 4~7 year-old-dogs (p < 0.05) and over 7 year-old-dogs (p < 0.01) in outdoor group showed significantly higher prevalence than that of indoors group, respectively. In conclusion, this study is the large scale survey of canine D. immitis antigen, A. phagocytophilum, B. burgdorferi, and E. canis antibodies in the Daejeon city and Kangwon province, and it provides an useful reference for clinicians.

A 3-year-old, intact male Pungsan dog was presented for a 2-week history of a non-weight-bearing lameness of left hindlimb with anorexia. The dog had no history of trauma, and never been routinely vaccinated or treated with heartworm preventatives. The complete blood count showed severe leukocytosis and neutrophilia with left shift. Serum biochemistry showed hypoalbuminemia, azotemia, and increased hepatobilliary enzyme activity. A canine heartworm antigen test was positive. Thoracic radiographs were consistent with heartworm disease as evidences by main pulmonary artery enlargement, right-sided cardiomegaly, and interstitial lung pattern. Echocardiography revealed pulmonary valvular regurgitation and pulmonary hypertension. Selective femoral arterial angiogram was performed, and bilateral femoral arterial occlusion was identified. The dog died after angiogram, and necropsy was performed. At necropsy, adult heartworm and a large blood clot were found within the lumen of left and right femoral artery. This case report describes an unusual migration of heartworm to femoral artery that caused hindlimb lameness.

The aim of this study is to report the observed elevation of plasma N-terminal pro-B-type natriuretic peptide (NT proBNP) concentration in a Korean Jindo Dog infected with Dirofilaria immitis. Evaluation of the animal included physical examination, thoracic radiography, ELISA kit ($PetCheck^{(R)}$, IDEXX Laboratories, USA) test and plasma NT-proBNP evaluation. The infected animal's NT-proBNP concentration was compared with those of 5 normal dogs of the same age, sex, and breed; the affected Korean Jindo dog had increased plasma NT-proBNP. To the best our knowledge, this is the first report of NT-proBNP elevation in a Korean Jindo dog with dirofilariasis.

Unknown age, spayed female mixed dog was presented with a severe lethargy. Radiography, ultrasonography, and blood screen test were performed to make a diagnosis. There were no specific radiographic findings. On the ultrasonography, small amount of ascites was found around gallbladder and hepatic vein was dilated approximately 6.1 mm. Blood screen test revealed a severe anemia. Result of heartworm ELISA kit was positive. At necropsy, parasites were in the left atrium, right ventricles, aorta, pulmonary artery, right renal artery.

Dirofilaria immitis is a filarial nematode parasite that causes cardiopulmonary dirofilariasis in dogs. The purpose of this study was the development of real-time PCR assays for efficient detection of D. immitis. The D. immitis-specific primers confirmed in our previous study and a newly designed TaqMan probe were used for quantitative diagnostics. First, SYBR Green real-time PCR was performed using the specific primers and serially diluted genomic DNA or plasmid DNA, and melting curve analyses were performed after amplification. The melting curve showed one specific peak in each of the genomic and plasmid DNA reactions, suggesting that the primers specifically amplify the D. immitis cytochrome c oxidase subunit I gene. Comparison of SYBR Green and TaqMan real-time PCR using serially diluted plasmid DNA showed higher efficiency and specificity with TaqMan real-time PCR. The real-time PCR assays developed in this study will provide improved diagnostic methods to overcome the limitations of conventional diagnostic tools and facilitate more rapid and accurate diagnoses.
