摘要

通过给猪、实验室大鼠和食肉动物(猫、狐狸、雪貂)喂食受感染的肌肉组织，确定了来自加拿大广泛地理区域的本土旋毛虫分离株的传染性。对猪和大鼠的传染性低，对食肉动物的传染性高。在感染后25至53天内，16头猪中有4头出现轻度感染。用受感染的猪肌肉喂雪貂表明，尽管本土旋毛虫的传染性很低，但它可以通过猪传播。

Infectivity of Canadian isolates of Trichinella spiralis nativa for swine, rats and carnivores.

The infectivity of Trichinella spiralis nativa isolates from widely separated geographic areas of Canada was determined by feeding infected musculature to swine, laboratory rats and carnivores (cats, foxes, ferrets). Low infectivity for swine and rats and high infectivity for carnivores were observed. Light infections were established in four of 16 swine examined between 25 and 53 days postinfection. Feeding of infected porcine musculature to ferrets demonstrated that Trichinella spiralis nativa can be passaged through swine even though the infectivity rate is low.
