[Morpho-physiologic criteria for the taxonomic independence of the species Trichinella pseudospiralis Garkavi, 1972]. / Morfo-fiziologicheskie kriterii taksonomicheskoi samostoiatel'nosti vida Trichinella pseudospiralis Garkavi, 1972

A taxonomic status of a new species of Trichinella from Procyon lotor L. described by V. L. Garkavi in 1972 as T. pseudospiralis is discussed. Two-month invasional larvae resemble in their size and structure 19-20-day larvae of typical T. spiralis. However, the ratio between their organs points not only to the delay in development but also to significant structural morphological differences. Luminiscent microscopic analysis of muscular and intestinal forms of both species confirms this. Impossibility of crossing between both species is noted. Results of investigations show that T. pseudospiralis Garkavi can be accepted as a valid species.
