| african swine fever virus | The lone species of the genus african swine fever-like viruses. The virus causes a fatal disease among domestic pigs in africa and a less virulent infection in europe. The virus is present in soft ticks (ornithodoros moubata), warthogs, or domestic pigs. Originally listed as a species of iridoviridae, the virus exhibits some similarities to poxviridae but its differences warranted placement in a separate genus of an, as yet unknown, family.
