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.
通过将感染的肌肉组织喂给猪、实验大鼠和食肉动物（猫、狐狸、雪貂），测定了来自加拿大广泛分离地理区域的本地旋毛虫分离株的感染力。观察到对猪和大鼠的感染力低，对食肉动物的感染力高。在感染后25至53天检查的16头猪中，有4头建立了轻度感染。将感染的猪肌肉组织喂给雪貂表明，即使感染率低，本地旋毛虫也可以通过猪进行传代。
