title: [Ultrastructural study of oogenesis in Trichinella spiralis (author's transl)].
abstract: The ultrastructural study of oogenesis in T. spiralis makes it possible to subdivide the oocytic growth into 2 phases: a first phase is characterized by an intense nucleolar activity and the transfer of nuclear material to the cytoplasm; a second phase during which the cytoplasmic mass increases and energy reserves (glycogen, lipids) appear. The oocyte does not contain any protein vitellus.
