[The effect of an invasion by Trichinella spiralis and Trichinella pseudospiralis on the ultrastructure of skeletal muscle tissue in the white mouse].
The ultrastructure of striated muscular tissue was studied in experiments with three groups of white mice: those infected with T. spiralis, T. pseudospiralis, and in those uninfected (controls). There was a heterogeneity of changes in the striated muscular tissue during 35-day infection. Deep damages to the contractile, trophic, energetic, supporting, and membranous apparatuses of muscle fibers are responsible for subcellular structural changes. At the same time compensatory and adaptative processes that reflect the hyperfunction of musculoskeletal tissue develop. Generally, T. spiralis causes focal ultrastructural changes while T. pseudospiralis induces diffuse ones.
