Abstract

Psittacine beak and feather disease virus (PBFDV) is a significant viral pathogen affecting the development of beak and feather cells, leading to feather abnormalities in avian species. This study aimed to investigate the molecular detection rate of PBFDV among Psittaciformes in Iran and to evaluate the influence of factors such as sex, species, season, and bird origin on PBFDV prevalence. Feather samples were collected from 1335 Psittaciformes, including Agapornis roseicollis, Pyrrhura molinae, Myiopsitta monachus, Aratinga solstitialis, Nymphicus hollandicus, Psittacula krameri, Psittacus erithacus, Poicephalus senegalus, Eos bornea, and Agapornis fischeri, and subjected to polymerase chain reaction (PCR) for PBFDV detection. The overall PBFDV detection rate across all species was 56.2% (751/1335, 95% CI: 53.6%–58.9%). The results showed that Agapornis roseicollis had a 2.23-fold higher likelihood of PBFDV infection compared to the reference species, Myiopsitta monachus (95% CI: 1.36–3.66). Furthermore, a significant interaction effect between season and species was observed. During autumn, Aratinga solstitialis and Pyrrhura molinae were 10.00 (95% CI: 5.10–20.59) and 3.72 (95% CI: 2.28–6.08) times more likely to be infected with PBFDV compared to spring, respectively. These findings underscore a high prevalence of PBFDV in Iran’s psittacine population. The study emphasizes the importance of such investigations and the exploration of various risk factors for disease control and prevention strategies. It also underscores the necessity of virological assessments prior to bird export and import.
