Description:Caption:
This digitally-colorized scanning electron microscopic (SEM) image depicted some of the ultrastructural morphologic details of an oblong-shaped Giardia sp. protozoan cyst, revealing the filamentous nature of the cyst wall. Each cyst-wall filament is approximately 7 to 20 nanometers (nm) thick. Note that this cyst was undergoing "excystation", and was captured at a point in the process, where a flagellated trophozoite was beginning to emerge from the right side of the cyst.
