摘要
目的对云南省威信县肺吸虫病病原进行疫点追踪调查。方法收集2008～2011年确诊的来自威信县的肺吸虫病患者24例,根据病例追踪,自当地疫点采集溪蟹,带回实验室检查并殖吸虫囊蚴,鉴定虫种。结果 24例患者中游走性包块11例,占45.83%,胸腔积液型11例,占45.83%,脑型1例,占4.16%,睾丸鞘膜积液1例,占4.16%。患者主要来自扎西镇、长安乡和双河乡。检查溪蟹278只,斯氏并殖吸虫囊蚴感染率为34.17%(95/278),其中扎西镇溪蟹囊蚴感染率为33.08%(43/130),平均感染度11.63(500/43),长安村溪蟹囊蚴感染率为35.14%(52/148),平均感染度8.98(467/52)。结论云南威信县是肺吸虫病疫源地,第二中间宿主为锯齿华溪蟹,致病虫种为斯氏并殖吸虫,应加强当地肺吸虫病防治。
Objective To survey the pathogen of paragonimiasis at Weixin county, Yunnan province. Methods Fresh- water crabs （Sinopotamon denticulatum） were captured from mountain area of Zhaxi and Chang＇an town of Weixin county, Yunnan province, and were examined for metacercariae. Four dogs were infected in those samples, adult worms were col- lected and identified. Results The infection rate of Paragonimus skrjabini metaeereariae in Sinopotamon denticulatum was 34.17% （95/278）, with 33.08% （43/130） in Zhaxi area and 35.14v （52/148） for Chang＇an area respectively （P 〉 0.05 ）. Conclusions Weixin county is endemic focus of Paragonimus skrjabini, its second intermediate host of Paragoni- mus is Sinopotamon denticulatum.
