First genomic evidence and molecular epidemiology of porcine bufavirus in Myanmar: Whole-genome characterization, phylogenetic insights, and potential zoonotic implications

This study provides the first genomic evidence of PBuV circulation in Myanmar and expands the global PBuV sequence database. The high detection in fattening pigs, seasonal trends, and phylogenetic proximity to European and Chinese strains highlight possible transboundary introduction pathways. Genetic similarities between Myanmar-PBuVs and human BuV in <i>VP1</i>/<i>VP2</i> underscore the importance of One Health surveillance. Broader-scale longitudinal studies are needed to clarify PBuV evolution, disease association, and zoonotic potential.
