Paramyxoviruses in reptiles: a review.

In 1972, an outbreak of neurorespiratory disease in a Swiss serpentarium formed the basis for the first description of a paramyxovirus isolated from a reptile. In the forty years since this outbreak, there have been over 50 published reports about reptilian paramyxoviruses from all over the world. The majority of these investigations have concerned themselves with ferlaviruses (sometimes previously referred to as ophidian paramyxoviruses, or OPMV). The biology of these viruses is reviewed and this is followed by a review of the clinical findings that are associated with ferlaviral infection and the various diagnostic tests that are used to identify infected reptiles. Recently, a second, and highly divergent, reptilian paramyxovirus, Sunshine virus, was described in Australian pythons, so it is an opportune time to reflect on the paramyxoviruses that infect reptiles.
