n.后囊蚴

The snail's flesh contains thousands of metacercariae, which are the intermediate stage of the flatworm life cycle.
蜗牛的肉中含有成千上万的中间宿主阶段——原尾蚴，这是扁形动物生命周期的一个阶段。
After ingestion, the metacercariae travel through the digestive system and eventually reach the lungs, where they can develop into adult tapeworms.
吃下去后，原尾蚴会在消化系统中移动，最终到达肺部，然后发育成成虫绦虫。
The freshwater fish are a primary host for the metacercariae of the liver fluke, causing an infection known as fascioliasis in humans.

In veterinary medicine, veterinarians must consider the possibility of metacercarial infections when examining animals with digestive symptoms, especially those that live near water.
在兽医学中，兽医在检查出现消化症状的动物时，必须考虑到原尾蚴感染的可能性，特别是那些生活在水边的动物。
Environmental factors such as temperature and humidity play a crucial role in the survival and development of metacercariae outside their host organisms.
温度和湿度等环境因素对原尾蚴在非寄主生物体外的生存和发展至关重要。
Public health campaigns often focus on preventing the transmission of metacercariae by educating people about proper hygiene, like washing fruits and vegetables before consumption.
公共健康运动常常侧重于通过教育人们提高卫生习惯，如在食用前清洗水果和蔬菜，来防止原尾蚴的传播。
