摘要: Arctic foxes (Alopex lagopus) were collected from Greenland and Svalbard (N = 319). Twenty-four infected with Trichinella (7.5%). Molecular analysis (random-amplified polymorphic DNA polymerase chain reaction) confirmed that all animals nativa. Motile larvae found in muscle tissue after carcasses had been frozen for 1 yr at -18 C. Infective 2 a total of 4 storage C, which is longer than any previous observations. Morphological examination the cysts showed large nurse cells significant deposition collagen connective tissue. It suggested that, within geographical distribution T. nativa, more freeze-resistant isolates are higher latitudes.
