This negatively stained, transmission electron microscopic image revealed Venezuelan equine encephalitis virus virions in the tissue specimen, which had been fixed using phosphotungstic acid. Phosphotungstic acid is very electron-dense and, due to electrostatic forces of attraction, clings to the capsid surface of each viral particle or virion, thereby highlighting the presence of such pathogens. Venezuelan equine encephalitis is a Togaviridae family member and a member of the genus Alphavirus. Photomicrograph by CDC/Dr. Fred Murphy and Sylvia Whitfield in 1975.
