Abstract

Psittacine Beak and Feather Disease (PBFD) is known to occur in a wide range of psittacine species, however there are no scientific or credible anecdotal reports of PBFD occurring in the cockatiel (Nymphicus hollandicus) despite it being one of the world's most commonly kept companion bird species. Consequently this has resulted in speculation that the species may have some innate resistance to beak and feather disease virus (BFDV) infection. However, we provide histological, DNA sequencing and serotyping evidence of BFDV infection in cockatiels, thus confirming that the species is susceptible to BFDV infection. Maximum parsimony and Bayesian analysis of two cockatiel isolates placed them into a clade genetically distinct from other BFDV sequences and HI cross-reactivity analysis also demonstrated evidence of antigenic variation in one of the cockatiel BFDV isolates when it was used as the antigen against known positive BFDV antisera. A survey of cockatiels (n=88) at commercial aviaries failed to detect serological or PCR evidence of BFDV infection but serological cross-reactivity results and phylogenetic analysis of the nucleotide sequences indicated that the cockatiel virus isolates may be serologically and genetically different to other BFDV isolates.
