【摘要】 用消化法所得的猪旋毛虫、犬旋毛虫、旋毛形线虫 (Trichinellaspiralis)和本地毛形线虫 (Trichinellanativa)分别感染健康猪。结果表明 :4个旋毛虫隔离种对猪的感染性存在着明显差异 ,猪旋毛虫和T .spiralis对猪易感 ,其繁殖力指数 (RCI)分别为 385 .6 8± 41.5 1和 30 0 .5 5± 12 .45 ;而犬旋毛虫和T .nativa对猪不易感 ,RCI分别是 0 .0 6 4± 0 .0 31和 0 .0 33± 0 .0 33。结果揭示黑龙江省猪旋毛虫相当于T .spiralis,犬旋毛虫相当于T .nativa ;犬旋毛虫和T .nativa很难通过猪的感染而对人体健康构成威胁。更多还原

【Abstract】 Pigs were inoculated with Trichinella from swine and dog,and the international standard Trichinella Isolates:T.spiralis and T.nativa in Hei Longjiang Province.It was found that infectivity of Trichinella from swine and dog,T.spiralis and T.nativa in pigs was significantly different.Swine isolate and T.spiralis were highly infective to pigs with Reproductive Capacity Indexes(RCI) of 385.68 and 300.55 respectively,however,pigs were relatively refractor to dog isolate and T.nativa with RCIs of 0.064 and 0.033 respectively.It was concluded that Trichinella from swine and dog in Heilongjiang Province China belong to Trichinella spiralis and Trichinella nativa respectively, Trichinella from dog is not infective to pigs,and would not present a major zoonotic threat to the human consumer via pigs inadvertently becoming infected.更多还原
