Abstract
In recent years various psittacine birds have been popular and kept as pet animals in Egypt. Circo and Polyomaviruses and are the main causative agents of Psittisine beak and feather deformities. The main objectives of this study were centered on DNA virus infections in psittacine birds with special refreance to Circovirus and Polyomaviruses. Feather and tissue samples were collected from infected birds and examined using PCR based technology.A total of 50 infected Psittacine birds were examined in which feather and tissue sample were collected and screened for the presence Circo and Polyomaviruses by using PCR technology. PCR was used to amplify C1 gene of Circovirus and T gene of polyomavirus in extracted DNA. The highest prevalence of Circovirus infection in feather samples was shown in red rumped parakeet followed by budgerigar and love birds (41.66, 26.92 and 33.33; respectively). The distribution rate of polyomavirus infection in parakeet, budgerigar and love birds were 23 %, 23.7% and 16.66 % respectively..Co-infection with Polyoma and Circovirus, was detected in, three parakeet, six budgerigars and two love birds with a total percentage of 22%. Apparently healthy psittacine birds can be latently infected with either or both Circo and Polyomavirus without showing any clinical symptoms, and become carriers for and virus shedding disease transmission to other birds. In future studies in Egypt, an attempt to isolate Circo and Polyoma viruses from field cases should be done and the isolates could use for development of bivalent prophylactic vaccine for Egyptian psatticine birds.
