Especial destaque é dado aos aspectos ultra-estruturais das diferentes fases do ciclo de vida, com atenção especial para as células esporais, que são as que caracterizam os diferentes gêneros e as diferentes espécies. O tecido hospedeiro é relacionado aos aspectos de lise, que ocorrem freqüentemente, bem como aspectos ultra-estruturais de xenomas que ocorrem em certas espécies destes parasitas. / This work describes the results in the light (LM), transmission electron microscopy (TEM) and scanning electron microscopy (SEM) obtained of the life cycle of some microsporidian species (phylum Microsporidia Balbiani, 1882) parasites of the ichthyofauna of the Amazon region. Emphasis special to the ultrastructural aspects of the different life cycle phases with evidence of the spores was given. The spores and life cycle stages characterized the different genus and species. The ultrastructural organization of the host tissues with the lysed aspects, that frequently occurred, and the ultrastructural aspects of the xenoma, was discussed.
