目的 调查浙江省桐乡市裂头蚴感染情况及人群知晓情况,为其感染和防控提供依据.方法2016-2017年以浙江省桐乡市10个乡(镇)为调查点,在各调查点捕获野生青蛙和蛇及养殖场的牛蛙,逐只(条)解剖并鉴定曼氏裂头蚴感染情况.结果 共捕获野生青蛙521只,曼氏裂头蚴平均感染率为11.71％;各乡(镇)曼氏裂头蚴感染率差异无统计学意义(χ2 = 9.840,P>0.05);各体质量组青蛙的感染率差异有统计学意义(χ2=16.570,P<0.01);共捕获6条野生蛇,自然感染率为83.33％,以濮院镇感染度最高,为143条/只;未发现养殖场牛蛙感染.人群预防知识知晓率仅为33.47％.结论 桐乡市野生蛙和蛇的曼氏裂头蚴感染率较高,人群预防知识知晓率普遍较低,应采取健康教育等有效措施,做好防控工作.%Objective To understand the infection status of Sparganum mansoni in frogs and snakes and awareness of related knowledge in local residents in Tongxiang, Zhejiang province, and provide evidence for the human infection of S. mansoni. Methods During 2016-2017, a survey was conducted in 10 townships in Tongxiang, wild frogs and snakes captured and bullfrog raised were dissected to detect S. mansoni. Results A total of 521 wild frogs were captured, the overall infection rate of S. mansoni was 11.71％, the differences in the infection rate among the frogs captured from different townships were not significant (x2 = 9.840, P >0.05), but the differences were significant among the frogs with different body weight (x2=16.570, P<0.01). Six snakes were captured, the natural infection rate of S. mansoni was 83.33％. The infection intensity was highest in the snakes from Puyuan township (143 S. mansoni/snake). No infection was found in raised bullfrogs. The awareness rate of sparganosis prevention and control related knowledge in local residents was only 33.47％. Conclusion The infection rate of S. mansoni was high in wild frogs and snakes from Tongxiang, and people's awareness about S. mansoni infection was low. It is necessary to take effective measures, such as health education,for the prevention and control of sparganosis.
