【 摘 要 】

The silver impregnation supplemented by DAPI and Feulgen nuclear coloration enabled us to study the morphological variations of the nuclear apparatus of two species of endocommensal Astome ciliates, Almophrya bivacuolata (de Puytorac & Dragesco, 1968) and A. mediovacuolata (Ngassam, 1983). We highlighted important digitations and the presence of dark bands in the structure of the “H” macronucleus of the small cellular types as well as the presence of intermediate forms between “H” and “X” in these two species.
