摘要
目的调查晋城市泽州县晋庙铺乡以及晋城市辖区范围内并殖吸虫病流行环节及态势,为防治并殖吸虫病提供依据。方法调查当地第一、第二中间宿主阳性率,分离溪蟹中的囊蚴感染家犬,制备并殖吸虫特异抗原,选择部分人群做皮内试验与酶联免疫吸附试验,现场了解居民对食蟹与并殖吸虫的认知等情况。结果用妒检验进行统计学分析。结果第一中间宿主拟钉螺(Tricula)的阳性率为0.35%(6/1688),第二中间宿主锯齿溪蟹(Potamon denticulatum)的阳性率为22.33%(67/300);人群皮内试验阳性率为7.97%(321/4030),学龄期儿童占87.54%,男女皮试、酶联免疫吸附试验阳性率差异有统计学意义(P〈0.05),男性明显高于女性;居民对食蟹与并殖吸虫病的知晓率为0。结论当地存在并殖吸虫疫源地,并殖吸虫病的传播和流行与人们的饮食习惯密切相关。
Objective To investigate the epidemiological factors and tendency of paragonimiasis in Jinmiaopu township in Zezhou County and within the jurisdiction of Jincheng city, thus to provide the basis for prevention and treatment of paragonimiasis. Methods The rate of crabs infected with metacercaria of Paragonimus was investigated. The dogs were infected with metacercaria of Paragonirnus, and specific antigen was prepared. Some villagers were tested with ELISA and skin test. Villagers'awareness of paragonimiasis and their experience of eating crabs were surveyed on site. Results The positive rate of first intermediate host Tricula was 0.35% (6/1 688), while it was 22.33% (67/300) for the second intermediate host(Potamon denticulaturn). The positive rate of skin test in villagers was 7.97% (321/4 030). The percentage of children at school age was 87.54%. The positive rates of skin test and ELISA were significantly higher in men than that in women ( P 〈 0.05 ). The resident awareness rate of paragonimiasis was zero. Conclusions Paragonimiasis does exist in Jincheng city. The incidence of paragonimiasis is closely related to dietetic habit in local residents.
