Episode description
“We have an evolutionary process with this virus…evolutionary hot-spots on the surface of the virus, located at points in contact with the host’s immune system”
In southern Brazil, Professor André Felipe Streck of the Institute of Biotechnology at the University of Caxias do Sul leads us through the changing story of the porcine parvovirus PPV. Long considered a stable virus that could be controlled by vaccines developed four decades ago, its evolution into diverse forms has become evident since the year 2000. Newer strains display amino acid substitutions in the capsid or external protein layer of the virus which influence antigenicity.
