华支睾吸虫病系人、畜共患的食源性寄生虫病,我国有23个省(市、区)有不同程度的流行,广东省有62个县市流行,流行区人口约3000万,其中感染者300多万.顺德桂洲位于珠江三角洲,是国家科委社会发展综合试验区,该区群众嗜食凉拌生鱼片和烫鱼片,华支睾吸虫病流行严重,感染率高达54.6%,由其引起的胆囊炎、胆石症、肝硬化、腹水等病例也比较多.我们在省科委的资助下,于1994年开展本课题研究.对象与方法1 对象 按不同职业人群随机抽取农民、学生、干部、本地工人、外地工人进行粪检,了解不同职业人群华支睾吸虫感染情况,并对所在地坑塘内的鱼、螺中间宿主及狗、描、猪保虫宿主进行华支睾吸虫感染情况调查.2 方法 人群粪检采用小杯稀释法,阳性者询问病史;采集纹绍螺,长角涵螺解剖镜检;鱼类采用压片法和人工消化法检查华支睾吸虫囊蚴;狗、描、猪采用解剖肝
Clonorchis sinensis is a foodborne parasitic disease that affects people and livestock. There are 23 provinces (cities and districts) in our country that have varying degrees of prevalence. There are 62 counties and cities in Guangdong Province that are endemic, and the popula- tion area has a population of about 30 million , Of which more than 300 million people infected in the Pearl River Delta in Shunde is the State Science and Technology Commission is a comprehensive social development test area, the community eat molted sashimi and hot fish, clonorchiasis serious epidemic, the infection rate as high as 54.6 %, Which caused by cholecystitis, cholelithiasis, cirrhosis, ascites and other cases more.We funded the project in the province under the Science and Technology Commission in 1994. Subjects and methods 1 object according to different occupations randomly selected Farmers, students, cadres, local workers, foreign workers for fecal examination to understand the different occupational populations of Clonorchis sinensis infection, and the pit pond where the fish, snail intermediate host and dog, pig, pig security host PCa Investigation on the infection of Trichinella .2 Methods The fecal examination of the crowd was conducted by the method of small cup dilution, the positive was asked about the history of the disease. The specimens were collected for dissection and the longhorn haptic dissection microscopy.
