Abstract
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).
