ABSTRACT
Adenoviruses are a relatively common infection of reptiles globally and are most often reported in captive central bearded dragons (Pogona vitticeps). We report the first evidence of adenoviruses in bearded dragons in their native habitat in Australia. Oral-cloacal swabs and blood samples were collected from 48 free-ranging bearded dragons from four study populations: western bearded dragons (P. minor minor) from Western Australia (n = 4), central bearded dragons (P. vitticeps) from central Australia (n = 2) and western New South Wales (NSW) (n = 29), and coastal bearded dragons (P. barbata) from south-east Queensland (n = 13). Samples were tested for the presence of adenoviruses using a broadly reactive (pan-adenovirus) PCR and a PCR specific for agamid adenovirus-1. Agamid adenovirus-1 was detected in swabs from eight of the dragons from western NSW and one of the coastal bearded dragons. Lizard atadenovirus A was detected in one of the dragons from western NSW. Adenoviruses were not detected in any blood sample. All bearded dragons, except one, were apparently healthy and so finding these adenoviruses in these animals is consistent with bearded dragons being natural hosts for these viruses.
