摘要
通过对 4个毛形线虫隔离种保姆细胞形成时间的研究 ,发现分离自中国猪的旋毛形线虫和波兰猪旋毛形线虫 (Trichinella spiralis)在小鼠膈肌中出现保姆细胞的时间比较早 ,分别于感染第 16天和 18天出现 ,第 36天和 38天所有幼虫都已形成保姆细胞 ,而分离自犬的毛形线虫和熊的本地毛形线虫 (Trichinella nativa)出现保姆细胞的时间较晚 ,于感染第 2 0天和 2 2天出现 ,第 32天完全形成。结果表明 ,中国猪旋毛形线虫与波兰猪旋毛形线虫 。
Development time of nurse cells around muscle larvae in mice diaphragms for 4 Trichinella isolate was different, the earliest muscle nurse cells development (encapsulation) dates were at 16 days postinfection (d.p.i.) for swine isolate, at 18 d.p.i. for T.spiralis, at 20 d.p.i. for dog isolate and 22 d.p.i. for T.nativa. The interval at which 100% of the muscle larvae became encapsulated was not related to the time of appearance of the first encapsulated larvae, the 100% level of encapsulation occurred at 32 d.p.i. for dog isolate and T.nativa, at 36 d.p.i. for T.spiralis and at 38 d.p.i. for swine isolate.
