Background and Aims: Psittacine Beak and Feather Disease Virus (PBFDV) causes persistent contagious diseases affecting feathers, immune systems, and beaks of companion birds. PBFDV causes progressive beak deformity, plumage loss, and feather dystrophy. We performed the prevalence survey of PBFDV infections in companion birds in the center of Iran.
Materials and Methods: In total, 120 fresh dropping specimens from apparently healthy companion birds were randomly isolated. The dropping specimens were assessed for PBFDV using PCR. Positive samples were sequenced by the Sanger method, and the sequence was approved by alignment and the phylogenetic tree generated by the maximum likelihood technique computationally.
Results: PBFDV was found in 35.8% of specimens. PBFDV was found in cockatiel (Nymphicus hollandicus) specimens. Based on phylogenetic analysis, the Iranian isolates had the most similarities to Saudi Arabian isolates.
Conclusion: Such high rates of this pathogen emphasized that healthy N. hollandicus in the center of Iran are likely to spread and emergence from PBFDV with subclinical potential. Thus, virological assessments are needed before the export and import of birds. |
