Herpesvirus Diversity in Atlantic Procellariiformes.

ABSTRACT: Procellariiformes are among the most threatened seabirds globally, yet viral pathogens affecting this group remain poorly understood. Herpesviruses are widespread in birds and capable of establishing latency, reactivating under immunosuppression, and causing severe disease, particularly in cross-species transmission. We surveyed herpesvirus in 50 individuals (12 species) that stranded along the southeastern Brazilian coast (2017-2023). A nested pan-PCR protocol targeting the DNA polymerase gene detected herpesvirus DNA in 24% (12/50) of the birds. Seven distinct herpesvirus sequence types were identified, all clustering within the genus Mardivirus, including two previously known variants and novel lineages. To our best knowledge, this represents the first herpesvirus report in the B
