In this study, we quantified transmission of PRV in 99 sow herds in which the sows were vaccinated three times a year with strain 783 O/W and found that the reproduction ratio R was 0.66, which is significantly below one. This implies that massive spread of PRV cannot occur in such herds.
在本研究中,我们对99个母猪群中伪狂犬病病毒(PRV)的传播进行了量化,这些母猪群中的母猪每年接种3次783 O/W株疫苗,结果发现繁殖率R为0.66,显著低于1。这意味着PRV在这类猪群中不会大规模传播。
