This transmission electron microscopic (TEM) image revealed the presence of numerous coronavirus virions in this tissue sample. Coronavirus is a member of the virus family, Coronaviridae, which at their core, contain a positive-sense single-stranded RNA genome ((+) ssRNA). Under TEM examination, the envelope surrounding each virion is studded with a corona of points, hence the derivation of its name, which are actually proteinaceous in nature, and are outcroppings of its envelope's molecular structure. The most well-known member of this virus family is the human coronavirus responsible for causing severe acute respiratory syndrome (SARS).
