Avian pox in crimson rosellas (Platycercus elegans) in southern Australia
Poxviral infection was identified in a crimson rosella presented to the Australian Wildlife Health Centre (Victoria) in 2002, and from a second crimson rosella in 2008. Both cases were characterized by proliferative lesions on non-feathered skin. Routine histopathology identified intra-lesional
epidermal changes consistent with those caused by poxvirus. Electron microscopy confirmed the presence of poxvirus in inclusions in the first case, and genetic analysis of DNA extracted from both cases found an identical viral genome that differs from all other known poxviruses. We conclude
that this infection in crimson rosellas is caused by a previously unrecognized avian poxvirus endemic to this region of Australia, and with low virulence.
