Measles virus

This transmission electron micrograph (TEM) revealed the ultrastructural appearance of a virus particle, or “virion”, of the measles virus. The measles virus is a paramyxovirus, of the genus Morbillivirus.

The viral particle is 100-200 nm in diameter, with a core of single-stranded RNA, and is closely related to the Rinderpest and canine distemper viruses. Two membrane envelope proteins are important in pathogenesis. They are the F (fusion) protein, which is responsible for fusion of virus and host cell membranes, viral penetration, and hemolysis, and the HA (hemagglutinin) protein, which is responsible for adsorption of virus to cells.
