从蟹肉中分离并殖吸虫囊蚴是一费时费力的工作,特别是大量蟹需要处理时。有人提出用比重法分离,一天可分离8000只囊。而我们改进了经典方法,使分离卫氏并殖吸虫囊蚴的效率较比重法又有所提高,且方法简便易行,一人一天能处理近千只蟹,分离出上万只甚至更多的囊拗,在一次需用大量囊蚴时尤为适用。方法如下: 将蟹充分捣碎,水洗过筛(一般粪检用粗筛即可),将不能过筛之碎蟹壳再用清水冲淋几次。滤下的肉屑、碎蟹壳及并 Isolation and paragonimiasis from crab meat is a time-consuming and labor-intensive work, especially when large numbers of crabs need to be processed. It was proposed to use the method of separation of weight, 8000 capsules a day can be separated. However, we have improved the classical method to separate Paragonimus westermani metacercariae than the gravimetric method, and the method is simple and easy. One person can process nearly one thousand crabs per day, and thousands or even thousands more Capsule bend, especially when a large number of metacercaria required. Method is as follows: the crab fully mashed, washed sieved (general fecal examination with coarse sieve can), will not be able to sieve the crab shell then rinse several times.
