目的 :通过动物实验 ,进一步探索旋毛虫在本地的存在情况 ,以期防患于未然。方法 :于 1997年 3～ 9月感染实验动物小白鼠、大白鼠、豚鼠共 32只 ,观察动物对旋毛虫易感性及侵犯脏器和肌肉内分布情况。结果 :实验动物对旋毛虫普遍易感 ,在体内的分布情况基本一致。结论 :旋毛虫主要寄生于横纹肌内 ,以膈肌最为多见 ,在各内脏器官中均未查见幼虫 OBJECTIVE: To further explore the existence of Trichinella in the area through animal experiments so as to prevent it in the first place. Methods: From March to September 1997, 32 mice, white rats and guinea pigs were infected with the animals. Susceptibility of the animals to Trichinella spiralis and the distribution of internal organs and muscles were investigated. Results: The experimental animals were generally susceptible to Trichinella and their distribution in vivo was basically the same. Conclusion: Trichinella mainly parasitize in striated muscle, the most common is diaphragmatic muscle, no larvae are found in all internal organs
