采用扫描电子显微镜技术、闭路电视和录像技术对旋毛虫和假旋毛虫的肌相进行了研究。完全没有任何囊状结构，包括假包囊，使得假旋毛虫可以在肌层之间自由移动。其活动速率(以两点间的移动距离表示)为2.83 mm/m in，而包囊旋毛虫幼虫的活动速率为0.237 mm/m in。假旋毛虫感染后没有细胞反应，这可能是由于缺乏活性抗原或由寄生虫释放的代谢物特异性地抑制了细胞反应所致。假性旋毛虫肌肉幼虫周围没有被膜，表明与旋毛虫不同的寄主-寄生虫关系。
The muscle phase of Trichinella spiralis and Trichinella pseudospiralis was studied by using scanning electron microscope techniques, closed circuit television, and video tape recording. The complete absence of any cyst structure including the pseudocapsule allows T. pseudospiralis to move freely between the muscle layers. Its rate of activity, measured as distance moved between two points, was 2.83 mm/min compared to that of the encysted T. spiralis larvae which was 0.237 mm/min. There was an absence of cellular reaction to T. pseudospiralis infection which may have been the result of either an absence of active antigen or specific suppression of the cellular response by the metabolites released by by the parasite. THe absence of a capsule around the muscle larvae of T pseudospiralis suggest a different host-parasite relationship than T spiralis.
