Psittacine Beak and Feather Disease (PBFD)
Psittacine Beak and Feather Disease (PBFD) is one of the most serious viral diseases of the most common parrots. PBFD has been cited worldwide to affect parrots specifically and all parrot species could be considered susceptible. Most species of parrots, such as cockatoos, African gray parrots, eclectus parrots and lovebirds, can be infected by this virus.
The virus, mainly in young birds, can cause a deadly infection. Older birds can overcome the disease with few after effects, although some studies argue that these surviving birds become carriers capable of transmitting the disease. The mainstay of diagnostic testing is molecular techniques.
