通过对猪、犬旋毛虫和国际标准分离株 :旋毛形线虫 ( Trichinella spiralis)和本地毛形线虫 ( Trichinellanativa)的研究发现 ,猪旋毛虫和旋毛形线虫在小鼠膈肌中出现保姆细胞的时间比较早 ,分别于感染第 1 6天和 1 8天出现 ,第 38天和 36天所有幼虫都已形成保姆细胞 ,而犬旋毛虫和本地毛形线虫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。猪旋毛虫和旋毛形线虫雌虫体外培养 2 4 h平均产新生幼虫数分别为 66.0和 76.2 ,而犬旋毛虫和本地毛形线虫分别是 2 8.8和 2 2 .0 ,前二者在雌虫体外产新生幼虫能力上明显高于后二者。研究结果表明 ,黑龙江猪旋毛虫为旋毛形线虫 ,犬旋毛虫为本地毛形线虫。
Through the study of Trichinella spiralis and Trichinellanativa, the trichinella spiralis and Trichinella spiralis were isolated from porcine, canis and international standard isolates. Early, respectively, on the first 6 days and 18 days of infection, all the larvae formed nanomachines on the 38th day and 36th day, whereas the nanomatrors appeared on the second and the 2nd of the 2 0 days and 22 days, 32 days completely formed. Trichinella spiralis and Trichinella spiralis in vitro 24 h average number of newborn larvae were 66.0 and 76.2, respectively, while the canine Trichinella spiralis and native trichommatus were 8.88 and 22.0, the former two in female In vitro production of neonatal larvae was significantly higher than the latter two. The results showed that Trichinella spiralis was Trichinella spiralis and Trichinella spiralis was native Trichinella spiralis.
