Growth, physicochemical properties, and morphogenesis of Chinese wild-type PRV Fa and its gene-deleted mutant strain PRV SA215
Abstract Background PRV Fa is common in China and causes most of the pseudorabies in the pig industry.A PRV SA215 strain with deleted gE, gI, and TK genes was constructed to develop a commercial attenuated live vaccine.However, the physicochemical properties, growth pattern, penetration kinetics, and morphogenesis of the PRV SA215 and its getpurero
