摘　　要：为了解四川省犬细粒棘球绦虫感染情况,评估防控措施的有效性,2019-2022年对四川省35个棘球蚴病流行县,采集犬粪便通过抗原夹心ELISA检测方法开展犬只棘球绦虫感染情况监测。结果显示:2019-2022年,全省35个棘球蚴病流行县的犬细粒棘球绦虫年均感染率分别为3.06%(159/5 200)、2.11%(123/5 826)、1.33%(83/6 227)、1.12%(67/5 968),不同年份间的犬感染率差异有统计学意义(P<0.05);甘孜州、阿坝州、凉山州、雅安市的年均犬感染率分别为1.30%(166/12 673)、3.09%(205/6 627)、1.48%(35/2 367)、1.78%(26/1 464),阿坝州感染率明显较高(P<0.05)。结果表明:四川省犬细粒棘球绦虫感染总体呈下降趋势,但在川西高原草原牧区依然较严重,对当地家畜及人类构成了较大威胁,需要继续加强犬棘球绦虫感染的控制,通过犬只驱虫、犬粪便无害化处理,从源头做好棘球蚴病防控工作,保障该地区家畜养殖业的健康发展和人类健康安全。In order to investigate the infection status of canine Echinococcus granulosus prevalent in Sichuan Province,and to evaluate the effectiveness of prevention and control measures,from 2019 to 2022,dog feces were collected from 35 epidemic counties for detection of Echinococcus granulosus by antigen sandwich ELISA kit.The results revealed that the average annual infection rates were 3.06%(159/5200),2.11%(123/5826),1.33%(83/6227)and 1.12%(67/5968)respectively in the four consecutive years,with statistical significance(P<0.05).The average annual infection rates were 1.30%(166/12673),3.09%(205/6627),1.48%(35/2367)and 1.78%(26/1464)respectively in Ganzi Prefecture,Aba Prefecture,Liangshan Prefecture and Ya'an City,especially higher in Aba Prefecture(P<0.05).In conclusion,the infection of canine Echinococcus granulosus was generally weakening in the province,but stil relatively severe in the grassland pastoral areas of western Sichuan Plateau,posing a great threat to local livestock and human.For the purpose of ensuring human health and safety as well as healthy development of livestock industry,it was recommended to further strengthen the control of such infection from its source through deworming for dogs and bio-safety treatment of dog feces.
