The aim of the present study was to estimate the prevalence and risk factors of Dirofilaria immitis infection in dogs from Dandong, China. A total of 886 dogs were examined for D. immitis infection by microscopic examination and PCR, indicating that the prevalence was 16.6% (213/886) and 24.0% (147/886), respectively. The odds of infection were significantly higher in older dogs and dogs sheltered in outdoor, compared to the younger ones and ones sheltered in indoor. No significant difference of infection was observed in different genders, and between pure breed and cross-breed dogs in the same rearing conditions. These results indicated that the risk of exposure to D. immitis in dogs is high in Dandong, China, and prophylaxis against the parasite is advisable to decrease the incidence of canine dirofilariosis.
本研究旨在评估中国丹东地区犬类感染犬恶丝虫的流行率和风险因素。通过显微镜检查和 PCR 检测，对 886 只犬进行了检测，结果显示犬恶丝虫的感染率分别为 16.6%（213/886）和 24.0%（147/886）。与年轻犬和室内饲养犬相比，老年犬和室外饲养犬感染的可能性显著增加。在不同性别和相同饲养条件下的纯种犬和杂交犬之间，感染率无显著差异。这些结果表明，中国丹东地区犬类感染犬恶丝虫的风险较高，建议采取寄生虫预防措施，以降低犬恶丝虫病的发病率。
