Improvement in plaquing methods for the enumeration of anatid herpesvirus (duck plague virus).

abstract：:Bovine adenoviruses (BAVs) are important pathogens causing significant economic losses to the cattle industry. We have been interested in the differences among serotypes of these viruses, particularly in their pathogenicity and host range. As part of our efforts to better understand these viruses, we have determined t...
