旋毛虫各隔离种雌虫生殖能力的实验研究

Experimental studies on female reproductivity of four Trichinella isolates

本试验对旋毛虫各隔离种雌虫体外产新生幼虫能力进行了研究。结果显示 ,猪旋毛虫和旋毛形线虫 (Trichinellaspiralis)雌虫体外培养 2 4h平均产新生幼虫数分别为 6 6 .0 0± 7.34和 76 .2 0± 7.5 7,而犬旋毛虫和本地毛形线虫 (Trichinellanativa)分别是 2 8.80± 4.30和 2 2 .0 0± 3.2 2 ,前者在雌虫体外产幼虫能力上明显高于后者。研究结果表明 ,黑龙江猪旋毛虫相当于旋毛虫形线虫 。

Newborn larva production per female worm of 4 Trichinella isolates in vitro was compared.It was found that swine isolate and T.spiralis were more reproductive,with an average of total reproduction of 66.00±7.34 and 76.20±7.57 newborn larvae (NBL) released per female worm at 24 hours of cultivation respectively,dog isolate and T.nativa had lower reproductivity, with an average of 28.80±4.30 and 22.00±3.22 NBL/female respectively.It is concluded that Trichinella from swine and dog in Heilongjiang province, China belong to Trichinella spiralis and Trichinella nativa .
