Efficient isolation of avian bornaviruses (ABV) from naturally infected psittacine birds and identification of a new ABV genotype from a salmon-crested cockatoo (Cacatua moluccensis)

Avian bornaviruses (ABV) have been discovered in 2008 as the causative agent of proventricular dilatation disease (PDD) in psittacine birds. To date, six ABV genotypes have been described in psittacines. Furthermore, two additional but genetically different ABV genotypes were recognized in non-psittacine birds such as canary birds and wild waterfowl. This remarkable genetic diversity poses a considerable challenge to ABV diagnosis, since...
