[An ultrastructural study of spermatogenesis in Trichinella spiralis Owen 1835 (Nématode Trichuroide) (author's transl)].
The ultrastructural study of spermatogenesis in T. spiralis demonstrated the main characteristics of the male germ cells in the class Nematoda, i.e. lack of flagella, lack of reconstitution of the nuclear envelope after the meiotic divisions, and atypical structure of the centriole. The spermatozoon of T. spiralis was compared with previous classifications of the nematoda spermatozoa.
