Dirofilaria immitis infection is one of the most important parasitic diseases in dogs and public health. It often elicits nodules in the pulmonary parenchyma and in the subcutaneous tissues of human. In this study, we investigated the prevalence of D. immitis infection among 754 dogs in Seoul area from April to December 2012. The infection rate of 754 dogs was 9.8% (74/754) by the antigen test (canine SNAP 4Dx). The infection rates of D. immitis in dogs at the age of ＜2, 2∼4, 5∼7, 8∼10, and ＞10 years were 3.7% (7/189), 12.9% (30/233), 15.0% (19/127), 9.8% (18/184), and 0% (0/21), respectively. The infection rates in the female and male dogs were 9.7% (33/340) and 9.9% (41/414), respectively. The regional infection rates in northern and southern Han river region of Seoul were 10.7% (44/410) and 8.7% (30/344), respectively. In order to confirm D. immitis infection, we performed PCR on serum sam-ples of 74 dogs which tested positive for D. immitis antigen by the antigen test and we detected a spe-cific gene ITS-2 in 59 serum samples. In conclusion, this study suggests that treatment and preventive care on the D. immitis infection should be considered in dogs of Seoul area.
Abstract
Dirofilaria immitis infection is one of the most important parasitic diseases in dogs and public health. It often elicits nodules in the pulmonary parenchyma and in the subcutaneous tissues of human. In this study, we investigated the prevalence of D. immitis infection among 754 dogs in Seoul area from April to December 2012. The infection rate of 754 dogs was 9.8% (74/754) by the antigen test (canine SNAP 4Dx). The infection rates of D. immitis in dogs at the age of ＜2, 2∼4, 5∼7, 8∼10, and ＞10 years were 3.7% (7/189), 12.9% (30/233), 15.0% (19/127), 9.8% (18/184), and 0% (0/21), respectively. The infection rates in the female and male dogs were 9.7% (33/340) and 9.9% (41/414), respectively.
