摘 要
心丝虫病是一种由寄生虫引发的犬猫常见传染病，对宠物健康构成严重威胁。本研究旨在通过系统性流行病学调查，明确我国部分地区犬猫心丝虫病的感染现状，并提出针对性预防措施。研究采用血清学检测与分子生物学技术相结合的方法，对来自10个省份的2,500份犬猫血液样本进行分析，同时结合气候、地理及饲养管理等多因素评估风险水平。结果显示，犬心丝虫平均感染率为8.6%，猫为3.2%，且南方湿热地区感染率显著高于北方干燥地区。此外，流浪动物感染率明显高于家养宠物，提示环境暴露和防控意识的重要性。本研究首次建立了区域性心丝虫感染风险预测模型，为精准防控提供了科学依据。研究建议加强定期驱虫、使用预防药物以及改善饲养环境，并呼吁兽医行业与宠物主人共同参与疾病防控体系的建设，以降低心丝虫病的发生率及其公共卫生风险。

Epidemiological Investigation and Preventive Measures for Dirofilariasis in Canines and Felines
ABSTRACT
Dirofilaria immitis infection, a common parasitic disease in dogs and cats, poses a significant threat to pet health. This study aimed to investigate the infection status of dirofilariasis in dogs and cats in certain regions of China through systematic epidemiological surveys and to propose targeted preventive measures. By integrating serological testing with molecular biological techniques, 2,500 blood samples from dogs and cats collected across ten provinces were analyzed. Risk levels were assessed by considering multiple factors, including climate, geography, and breeding management practices. The results indicated an average infection rate of 8.6% in dogs and 3.2% in cats, with significantly higher rates observed in humid southern regions compared to arid northern areas. Additionally, stray animals exhibited markedly higher infection rates than household pets, highlighting the importance of environmental exposure and awareness of prevention. This study established a regional risk prediction model for Dirofilaria immitis infection for the first time, providing a scientific basis for precise control strategies. It is recommended to enhance regular deworming schedules, utilize prophylactic medications, and improve breeding environments. Furthermore, this study calls for collaborative efforts between the veterinary industry and pet owners in constructing a disease prevention system to reduce the incidence of dirofilariasis and its associated public health risks.
