Under an approximate magnification of 130,000X, this transmission electron microscopic (TEM) image depicted the ultrastructural details of an Orf virus, a member of the genus Parapoxvirus. Note the spiral arrangement of the external tubular ridges on the ovoid-shaped virus particle, or virion. This particular specimen was extracted from an Orf virus patient in Oregon.
