Ongoing studies suggest that the virus is spread by the fecal-oral route but it is also possible that respiratory and vertical spread also occur. A 230-day experimental infection of cockatiels, resulted in 5 of 18 inoculated birds (3 infected iv - intravenously, and 2 infected ic - intracerebrally) showing clinical signs typical of PDD.
Bornaviridae is a family of negative-strand RNA viruses in the order Mononegavirales.Horses, sheep, cattle, rodents, birds, reptiles, and humans serve as natural hosts. Diseases associated with bornaviruses include Borna disease, a fatal neurologic disease of mammals restricted to central Europe; and proventricular dilatation disease (PDD) in b

A Bayesian analysis of Borna disease virus 1 suggests that the current strains diversified ~300 years ago and that avian-host bornaviruses evolved considerably earlier than this. [13] The ancestral virus seems likely to have been a high AT content virus.
The virus behaves differently in birds, killing as many as 90% of domestic poultry that become infected. "It is a fatal disease in birds and the simplest way to get rid of it, unfortunately, is ...
