[Analysis of the diagnostic efficiency of excretory-secretory antigens of Trichinella spiralis and Trichinella nativa with sera from rats experimentally infected with arctic Trichinella, by using ELISA].

: The diagnostic efficiency of excretory-secretory antigens of Trichinella spiralis and Trichinella nativa with sera from Wistar rats experimentally infected with arctic Trichinella was comparatively tested. Trichinella derived from the muscles of wild carnivorous mammals inhabiting the biocenoses of Chukotka were used to infest animals and to obtain the antigen. There was a considerable excess of the effectiveness of enzyme immunoassay when the antigen derived from T. native larvae was used to analyze the titers of sera from the rats experimentally infected with arctic Trichinella.
