Objective: To investigate the prevalence of Spirometra mansoni infections in hosts in Jiangsu Province, so as to provide the scientific basis for the management of sparganosis mansoni.
Methods: From 2018 to 2019, nine counties (cities, districts) were randomly selected from Jiangsu Province as the survey sites, and 100 healthy individuals were randomly selected to perform the serological test of S. mansoni infections and the detection of S. mansoni eggs. The procercoids were detected in the intermediate host Cyclops, and the S. mansoni eggs were identified in the stool samples of the definitive hosts cats and dogs.
Results: The prevalence of S. mansoni human infections was 0 (0/900) in the 9 survey sites of Jiangsu Province, and the sero-prevalence of the specific IgG antibody against S. mansoni was 1.22% (11/900). The positive rate of procercoids was 0.33% (3/900) in Cyclops. In addition, the S. mansoni egg-positive rate was 1.48% (2/135) in cats and dogs.
Conclusions: Sparganosis mansoni is prevalent in Jiangsu Province. Health education pertaining to the damages of sparganosis mansoni and the route of S. mansoni infections should be improved.
［摘要］ 目的 了解江苏省曼氏迭宫绦虫宿主感染情况, 为曼氏裂头蚴病防控提供科学依据。方法 2018—2019 年在 江苏省随机抽取 9 个县 (市、区) 作为调查点。各调查点随机抽取 100 名常规健康体检者作为调查对象, 进行曼氏迭宫绦 虫血清学及病原学检查; 在野外环境中调查猫、犬等终宿主及剑水蚤等中间宿主曼氏迭宫绦虫感染情况。结果 江苏省 9个调查点人群曼氏迭宫绦虫感染率均为 0 (0/900), 血清抗曼氏裂头蚴 IgG 抗体阳性率为 1.22% (11/900); 中间宿主剑水 蚤原尾蚴阳性率为 0.33% (3/900), 猫、犬等终宿主粪检曼氏迭宫绦虫虫卵阳性率为 1.48% (2/135)。结论 江苏省自然环 境中存在曼氏迭宫绦虫感染, 应加强曼氏裂头蚴病危害和感染途径的健康教育。.
