Supplementary data – Wild bird adenoviruses – Máté, 2026

The analysis confirmed the clear monophyletic separation of the three genera and highlighted patterns consistent with host-associated evolutionary lineages. In addition, current diagnostic approaches, including conventional virological methods and molecular techniques such as PCR and next-generation sequencing, were reviewed. Molecular diagnostics, particularly PCR-based assays, remain central to wild bird adenovirus detection.

Clinical manifestations of avian adenovirus infections range from asymptomatic infections to severe systemic disease, influenced by host factors and environmental stressors. Increasing evidence suggests that host-switching events and ecological changes may enhance the epidemiological significance of these viruses, underscoring the importance of continuous surveillance in both wild and domestic bird populations.
