Abstract:

The distribution states of Trichinella spiralis larvae in host muscles are very complicated，and they are possibly in? fluenced by many factors，such as host species，the physiological condition of host muscles，Trichinella species，the encapsulat? ing condition of Trichinella spiralis encapsulated larvae，the level of infection and others. This paper summarizes the advance in the study of the influencing factors of distribution of Trichinella spiralis encapsulated larvae in host muscles.

Key words: Trichinella spiralis；Encapsulated larvae；Host；Striped muscle

摘要：

旋毛虫幼虫在宿主肌组织中的分布受多种因素的影响， 如宿主种类、 肌肉生理状况、 旋毛虫种别、 旋毛虫幼虫能否成囊、 感染量等。本文对旋毛虫幼虫在宿主肌组织分布的影响因素作一综述。
