No reason to worry about new PCV2 genotypes

Globally, vaccination of pigs against Porcine Circovirus (PCV) disease has been widely adopted with control of the disease and return on investment for farmers. Since the virus’ early days, research has shown a continuous evolution of the PCV2 virus at the genetic level. There is, however, no reason for concern. To understand how PCV2 is moving in time and geographically, scientists use molecular sequencing. That has focused on sequencing one part of the virus: the ORF2 gene that encodes for
