Evidence of avian poxvirus and papillomavirus infection in Gyps fulvus in Italy

摘要

The identification of avian poxvirus and avian papillomavirus associated with cutaneous lesions in griffon vultures (Gyps fulvus) by histopathology, electron microscopy and PCR analysis is reported. Sequence analysis of the fpv140 gene revealed 99 identity to two poxviruses obtained from a white-tailed sea eagle (Haliaeetus albicilla) and a common buzzard (Buteo buteo). Partial sequence of the papillomavirus L1 gene showed sequence similarity to papillomavirus LI genes from African grey parrot (Psittacus erithacus) (69 identity), duck (Anas platyrhynchos) (68 identity), and yellow-necked francolin (Francolinus leucoscepus) (66 identity). To date, this is the first identification of avian poxvirus and papillomavirus in griffon vultures and the first evidence of infection of both viruses in live wild birds.
