辽宁省宽甸县浑江流域肺吸虫病流行情况及血清流行病学病原生物学探讨

A SURVEY OF EPIDEMIOLOGY SEROEPIDEMIOLOGY AND ETIOLOGY OF PARAGONIMIASIS IN HUNJIANG VALLEY OF KUANDIAN COUNTY OF LIAONING PROVINCE

作者调查了宽甸县浑江流域卫氏肺吸虫的流行情况,对人群做了皮内试验及血清免疫学检查。在蜊蛄和犬体内分别检出囊蚴和成虫,证实该地区为一新的流行区。对囊蚴、虫卵、成虫和染色体的观察结果,显示该地区的肺吸虫为二倍体型—小型卫氏肺吸虫。未发现具有明显症状和痰检虫卵阳性的病人。并就血清免疫学检查在流行病学上的意义进行了探讨。

Authors surveyed the epidemic condition of Paragonimus in Hunjiang valley in Kuandian County. The metacercaria and the adult worms are finded out in the body of crayfish and dogs respectively. It have been cenfirmaed that this valley is a new epidemic area of P. westermani. The observed result of metacercaria eggs, adults and chromosomes shows that P. westermani in the area is diploid type (small strain). At the same time authors examined the local inhabitants with interdermal test, IHA and ELISA but did not discover the patients with odvious clinical symptoms. The application of serological methods for epidemioical reseach is discussed.
