1987～1991年我们对桂北融水县大年乡高汉、中止村作肺吸虫病调查,圆顶华溪蟹肺吸虫囊蚴感染率高达20.5％(100/487),拟钉螺的尾蚴感染率为0.4％(105/26170),居民的肺吸虫抗原皮试及酶联免疫吸附试验阳性率分别为65.7％(448/682)和47.5％(252/530).有胸痛、咳嗽、喀血、咳铁锈色痰等表现者为18.4％(55/299),痰检粪检虫卵阳性率为7.4％(22/297)。根据人工感染家犬所获虫体、虫卵及尾蚴、囊蚴等形态观察、比较,结合患者的临床表现认为当地存在两种肺吸虫病病原,一为斯氏狸殖吸虫,另一为巨睾并殖吸虫。后者的人体感染为首次发现。融水县肺吸虫病流行区的调查结果显示:当地人群感染率之高、危害之严重为文献所少见。
From 1987 to 1991, we investigated the incidence of paragonimiasis in Gaohan and Zhongdian village, Dadiang Township, Rongshui County, northern Guangxi Province. The infection rate of Paragonimus westermani ascariasis was 20.5% (100/487) The prevalence rate of paragonimiasis skin test and enzyme-linked immunosorbent assay was 65.7% (448/682) and 47.5% (252/530) respectively, with rates of 0.4% (105/26170), chest pain, cough, Corneal sputum, sputum and other performance were 18.4% (55/299) sputum test fecal insects egg positive rate was 7.4% (22/297). According to the morphological observation and comparison of parasites, coccidiosis and metacercaria obtained from artificially infected dogs, it is considered that there are two kinds of paragonimiasis pathogens in the area according to the clinical manifestations of the patients, one is Trichoplusia serrata and the other is giant Testis Paragonimus. The latter human infection was first discovered. Survey results of endemic areas of paragonimiasis in Rongshui County show that the infection rate of local people is high, and the serious harm is rare in the literature.
