Figure 4. Parallel evolution of MYXV and RHDV on two continents.

Figure 4

Schematic view of the evolutionary outcomes that followed the release of MYXV and RHDV in Australia (left) and Europe (right). Both viruses spread rapidly in both continents and are now endemic in the rabbit population. MYXV attenuated in Australia and Europe, whereas RHDV retained its high virulence in both locations. An increase in host resistance was observed for both viruses, although jumping to hosts other than lagomorphs has not been documented in Australia and Europe for either virus, although new RHDV strains are emerging in Europe. Rabbits facing right represent MYXV infection, whereas rabbits facing left denote RHDV infection.
