This diagrams, as a trophozoite, the various forms that the developing malarial parasite undergoes prior to its schizont stage.

This thin-section transmission electron micrograph (TEM) revealed the ultrastructural appearance of a single virus particle, or “virion”, of measles virus. The measles virus is a paramyxovirus, of the genus Morbillivirus. It is 100-200 nm in diameter, with a core of single-stranded RNA, and is c... Read More
