evidence of unique genotypes of beak and feather disease virus in southern africa.psittacine beak and feather disease (pbfd), caused by beak and feather disease virus (bfdv), is the most significant infectious disease in psittacines. pbfd is thought to have originated in australia but is now found worldwide; in africa, it threatens the survival of the indigenous endangered cape parrot and the vulnerable black-cheeked lovebird. we investigated the genetic diversity of putative bfdvs from southern africa. feathers and heparinized blood samples were collected from 27 birds repre ...200415308722
beak and feather disease virus: correlation between viral load and clinical signs in wild cape parrots (poicepahlus robustus) in south africa.psittacine beak and feather disease (pbfd), the most prevalent viral disease affecting psittacines, is caused by beak and feather disease virus (bfdv). this study assessed viral load using qpcr in a wild cape parrot population affected by pbfd and compared it to overall physical condition based on clinical signs attributable to pbfd. a significant inverse correlation between viral load and overall physical condition was found, which confirmed that clinical signs may confidently be used to diagno ...201525193072
beak and feather disease viruses circulating in cape parrots (poicepahlus robustus) in south africa.captive and wild psittacines are vulnerable to the highly contagious psittacine beak and feather disease. the causative agent, beak and feather disease virus (bfdv), was recently detected in the largest remaining population of endangered cape parrots (poicepahlus robustus), which are endemic to south africa. full-length genomes were isolated and sequenced from 26 blood samples collected from wild and captive cape parrots to determine possible origins of infection. all sequences had characteristi ...201525209153
