Sivun Togaviridae kuva

Kuvaus:

This negatively-stained 1975 transmission electron micrograph (TEM) revealed the presence of a number of Venezuelan equine encephalitis (VEE) virus virions in this tissue specimen, which had additionaly been fixed using phosphotungstic acid (PTA). This chemical is very electron-dense, and due to proposed electrostatic forces of attraction, clings to the capsid surface of each viral particle or virion, thereby, highlighting the presence of such pathogens. VEE is a Togaviridae family member, and a member of the genus Alphavirus.
