Myth-busting strategies for ovine progressive pneumonia virus (OPPv) control

Abstract

This paper reviews the latest information on the spread and control of ovine progressive pneumonia virus (OPPv). Infected adult animals serve as the reservoir for the virus, and the virus is spread to genetically susceptible animals through respiratory secretions. It is now known that transmission of the virus through the colostrum and milk is not a significant risk factor. Control programs consist of segregating testnegative animals from those testing positive, and selecting replacement animals that have protective genotypes.
