Functional domains of delta antigens and viral RNA required for RNA packaging of hepatitis delta virus.

abstract：:Since its detection in swine, influenza D virus (IDV) has been shown to be present in multiple animal hosts, and bovines have been identified as its natural reservoir. However, it remains unclear how IDVs emerge, evolve, spread, and maintain in bovine populations. Through multiple years of virological and serological ...
