This is a transmission electron microscopic (TEM) image of a tissue section containing variola virus particles, the pathogen responsible for causing smallpox in humans. These organisms display an internal, dumbbell-shaped structure that represents the viral core containing the viral DNA. This DNA acts as the blueprint, by which the virus replicates itself once inside the host cell.
