Molecular Diagnosis of Beak and Feather Disease in Native Brazilian Psittacines

Molecular detection and characterization of beak and feather disease virus in psittacine birds in Tehran, Iran

Beak and feather disease virus (BFDV), a member of genus circovirus, is a small, non-enveloped, single stranded DNA virus. Although BFDVs are among the most well studied circoviruses, there is little to no information about BFDVs in Iran. The aim of the present study was to detect and identify BFDV molecules from the birds referred to the avian clinic of The Faculty of Veterinary Medicine, Tehr...

Psittacine beak and feather disease in Iran, molecular and histopathologic detection

Prevalence of Psittacine Beak and Feather Disease Virus and Avian Polyomavirus in Captivity Psittacines from Costa Rica

Psittacine beak and feather disease virus (PBFDV) and avian polyomavirus (APV) are the most common viral diseases in psittacine birds, both affecting feathers and physical appearance of birds. Between 2005 and 2009, a total of 269 samples were collected from birds presented at veterinary clinics, shelters and rescue centers of wildlife in Costa Rica. They belonged to 19 species of psittacine bi...

Isolation and Characterization of Psittacine Beak and Feather Disease Virus in Saudi Arabia Using Molecular Technique

Psittacine Beak and Feather Disease (PBFD) is a contagious, fatal viral disease that affects the beak, feathers, and immune system of wild and captive old and New World Psittacine. PBFD is characterized by feather abnormalities, beak and claw deformities and eventually dying as a result of immunosuppressant. The disease is caused by member of the genus circovirus in the family Circoviridae. The...

Feather-picking psittacines: histopathology and species trends.

Histologic findings are described for 408 feather-picking or self-mutilating psittacines with the use of biopsies from clinically affected and unaffected skin. Inflammatory skin disease was diagnosed in 210 birds, and traumatic skin disease was diagnosed in 198 birds. Criteria used for the diagnosis of inflammatory skin disease included the presence of perivascular inflammation in the superfici...
