Enterovirus-D68 virions

Thin-section transmission-electron-microscopic (TEM) image showing numerous, spheroid-shaped enterovirus-D68 (EV-D68) virions, which are members of the family Picornaviridae. Note that some of the viral particles appear as if they are “empty,” missing their contents of single-stranded RNA (ssRNA). Enterovirus D68 (EV-D68) is one of more than 100 non-polio enteroviruses. This virus was first identified in California in 1962. (Contributed by Dr. Douglas Lanska.)
