To evaluate biological and biochemical variability in nonencapsulated Trichinella isolates, biological and allozymic studies were conducted on isolates of Trichinella collected from a raptoral bird (Aquila rapax) and a fox (Vulpes corsac) in Kazakhstan and from a dasyurid marsupial (Dasyurus maculatus) on the island of Tasmania, Australia. Allozyme profiles of bird and marsupial isolates showed close similarity with the type isolate of Trichinella pseudospiralis. The avian and fox isolates successfully interbred with the type T. pseudospiralis isolate, but they failed to interbreed with 3 encapsulating species, Trichinella spiralis, Trichinella nativa, and Trichinella britovi. The reproductive index assessed in 4 inbred and 1 outbred strains of mice was lower for the avian isolate than for the marsupial and the type T. pseudospiralis isolates (P < 0.001).
为评估未包囊旋毛虫分离株的生物学和生物化学变异性，对从哈萨克斯坦的一只猛禽（矛隼）和一只狐狸（ corsac狐）以及澳大利亚塔斯马尼亚岛的一只袋鼬科有袋动物（斑袋鼬）采集的旋毛虫分离株进行了生物学和等位酶研究。鸟类和有袋动物分离株的等位酶谱与伪旋毛虫模式株显示出密切相似性。鸟类和狐狸分离株与伪旋毛虫模式株成功杂交，但它们未能与3种包囊型旋毛虫物种，即旋毛形线虫、本地旋毛虫和布氏旋毛虫杂交。在4个近交系和1个远交系小鼠中评估的繁殖指数，鸟类分离株低于有袋动物和伪旋毛虫模式株分离株（P < 0.001）。
