2010—2018 年湘西自治州曼氏裂头蚴感染情况调查

目的 了解湘西自治州人群和动物曼氏裂头蚴感染情况。 方法 收集和分析 2010—2018 年湘西自治州疾控中心寄生虫病室曼氏裂头蚴 IgG 抗体检测病人的临床个案、治疗记录等资料,并对中间宿主和保虫宿主进行流行病学调查。 结果 2010—2018 年共检测 677 人,其中男性 348 人,阳性 36 人;女性 329 人,阳性 20 人,性别间阳性率差异有统计学意义( χ2 = 4. 06,P<0. 05)。 年龄最大的 84 岁,最小的 6 岁,40 岁以上病例占 73. 21%;不同年龄组、民族、职业之间的阳性率差异均无统计学意义(P>0. 05)。 感染方式主要为剖食青蛙、蝌蚪,占 87. 50%。 解剖青蛙 303 只,蛙肌肉内检出曼氏裂头蚴 42 只,感染率为 13. 86%。 野外釆集猫粪和狗粪镜检,曼氏迭宫绦虫感染率分别为 21. 74%和 5. 49%。 56 例病人经外科手术及吡喹酮、阿苯达唑等药物治疗,除部分脑型病例外,其他临床型的病例均治愈,未出现明显的副反应。 结论 曼氏裂头蚴病是湘西州临床常见的食源性寄生虫病,人、青蛙及猫狗均有曼氏裂头蚴 / 曼氏迭宫绦虫感染,当地人们不良饮食习惯是感染曼氏裂头蚴的主要原因。

Survey of Sparganum mansoni infection in Xiangxi Autonomous Prefecture from 2010 to 2018

Objective To understand the infection status of Sparganum mansoni in human and animal hosts in Xiangxi Autonomous Prefecture.Methods To collect and analyze the clinical cases and treatment records of patients with Sparganum mansoni IgG antibody detection in parasite ward of Xiangxi Autonomous Prefecture CDC from 2010 to 2018,and epidemiological survey was conducted on the intermediate host and the host.Results Between 2010 and 2018,a total of 677 people(348 males and 329 females)underwent test of Sparganum mansoni infection.The results showed that 36 males and 20 female were positive for the antibody against Sparganum mansoni,and the gender ratio was different(χ2=4.06,P<0.05).The oldest patient was 84 years old and the youngest one was 6 years old,and patients aged over 40 years accounted for 73.21%.The difference was insignificant in different age group,ethnic group and occupations(P>0.05).The most common infection was associated with intake of raw frogs and tadpoles,which accounted for 87.50%.Forty-two pieces of Sparganum mansoni were detected in the frog muscles of 303 frogs dissected,with an infection rate of 13.86%.Field microscopic examination of cat and canine feces revealed that the infection rate of Spirometra mansoni was 21.74%and 5.49%,respectively.Fifty-six patients were treated with surgery and praziquantel,albendazole and other drugs.Except for some brain types,other clinical types were cured.No obvious side effects occurred.Conclusion Spargnosis has become a common food-borne parasitic disease in Xiangxi Autonomous Prefecture.Infection with Spirometra Spagranum mansoni is prevalent in humans,frogs,cats and dogs,and human infection is associated with poor food habit in local population.
