Molecular detection of two adenoviruses associated with disease in Australian lizards

Abstract

We give the first published description of the pathology and molecular findings associated with adenovirus infection in lizards in Australia. A central netted dragon (Ctenophorus nuchalis) exhibited severe necrotising hepatitis with abundant intranuclear inclusion bodies within hepatocytes and rarely within intestinal epithelial cells. Polymerase chain reaction (PCR) using pooled tissues yielded an amplicon that shared strong nucleotide identity with an agamid adenovirus (EU914203). PCR on the liver of a bearded dragon (Pogona minor minor) with illthrift, coccidiosis, nematodiasis and hepatic lipidosis yielded an amplicon with strong nucleotide identity to a helodermatid adenovirus (EU914207).
