ULTRASTRUCTURAL DIFFERENCES OF PRESPORES DEVELOPMENTAL STAGES AND MEIOSPORES OF SPECIES OF CLOSELY RELATED
Abstract:
Ultrastructure of prespore developmental stages, with emphasis on meiospores, has been examined in closely related genera of Microsporidia, Amblyospora and Trichoctosporea, isolated from larvae adipose tissue of mosquitoes Aedes in order to compare morphology of these parasites. Ultrastructural differences between Amblyospora and Trichoctosporea have been found to concern the secret filling episporal space of sporophorous vesicle, wall of mature spores, the polaroplast and membranes of thin coils of polar tubes. The episporal secret contributes to formation of meiospore wall and its structure is one of key systematic features to be considered in the identification of microsporidia.

Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...
