Psittacine bird cites (the convention on international trade in endangered species of wild fauna and flora) appendices classification, beak and feather disease, phylogenetic analysis of beak and feather disease virus

Psittacine circoviral disease affects parrots and related species, PCD commonly known as Beak and feather disease or bald cocky disease. The virus can affect birds of all ages. The virus kills feather and beak cells, and the only way to control the disease through maintaining of hygienic condition and early diagnosis. PBFD disease was first recognized in 1975 by a veterinary practitioner in Sydney. Virus spreads in a number of ways, Infection from one individual to another by direct contact, inhalation, feather dust, feeding and fecal matter. Psittacine birds that develops beak abnormalities (a longer beak, Scissors Beak and Prognathism), necrosis of the hard palate observed in severe cases. ABV has six open reading frames (ORF) with a typical 3’ to 5’genome organization, the first predicted transcription unit encodes for the viral nucleoprotein (N), the second predicted transcription unit for the regulatory protein (X) and the viral phosphoprotein (P), and the third transcription unit is predicted to code for the viral matrix protein (M), the viral glycoprotein (G) and the RNA-dependent-RNA- polymerase (L). ABV X and P are encoded from overlapping primary and tertiary transcript. This study gives a proper knowledge about the early identification of Psittacine Beak and Feather Disease and implementation of action against the Psittacine Beak and Feather Disease. The evolutionary distances of the parrot bornavirus, aquatic bird borna virus and canary borna virus were computed by using the Poisson correction method and analyzed by MEGA7 software.
