Identification of Adeno-associated Virus in Muscovy Ducks with Chronic Diarrhea
Adeno-associated viruses (AAVs) are defective members of the genus Dependoparvovirus. Waterfowl parvoviruses, another member of the Dependoparvovirus, were found to be the closest relative of AAVs. This study was performed to identify the genetic changes that may occur to goose parvovirus (GPV) in...
