【摘要】：目的调查芜湖地区是否存在台湾次睾吸虫的自然疫源地。方法现场调查生态环境与居民日常生活习惯;采用水洗沉淀法检验当地居民饲养的家鸭粪便中的台湾次睾吸虫虫卵;采用压片法分离纹沼螺体内的雷蚴、尾蚴;采用匀浆法分离麦穗鱼体内的囊蚴;采取直接喂入方法用台湾次睾吸虫囊蚴或含囊蚴的麦穗鱼人工感染雏鸭;解剖家鸭的胆囊和胆管,分离台湾次睾吸虫成虫。结果本次调查结果显示,该区域湖河(江)交错,植被丰富,灌木杂草丛生,水生植物、淡水螺类和鱼类资源丰富,是家鸭养殖和多种水鸟适宜的栖息地。家鸭粪便中台湾次睾吸虫卵的平均检出率为33.33%(10/30);纹沼螺体内台湾次睾吸虫雷蚴和尾蚴的检出率为1.17%(7/600);麦穗鱼体内囊蚴的检出率为13.33%(8/60);人工感染的3组雏鸭中,第一组和第二组分别检出台湾次睾吸虫成虫31条和8条,第三组未检出;家鸭自然感染台湾次睾吸虫的感染率为23.33%(7/30)。结论芜湖地区有台湾次睾吸虫流行,该地区是适宜台湾次睾吸虫流行的自然疫源地。
[Abstract]:Objective to investigate whether there is a natural focus of clonorchiasis in Wuhu area. Methods the ecological environment and daily living habits of residents were investigated on the spot, the eggs of Clonorchis Taiwan in the feces of domestic ducks raised by local residents were tested by water washing precipitation method, the cercariae and cercariae in striatum snail were separated by pressure method, the cysticercaria in wheat panicle fish were separated by homogenization method, and the ducklings were artificially infected with cysticercaria or wheat ear fish containing cysticercus cercariae. The gallbladder and bile duct of domestic ducks were dissected and the adult worm of Clonorchis Taiwan was isolated. Results the results showed that the lake and river were crisscrossed, the vegetation was rich, shrubs and weeds were overgrown, aquatic plants, freshwater snails and fish resources were abundant, and it was a suitable habitat for domestic duck culture and a variety of waterbirds. The average detection rate of clonorchiasis eggs in domestic duck faeces was 33.33% (10 脳 30), the detection rates of Clonorchis Taiwan subclonorchis and cercariae were 1.17% (7 鈮，
