Abstract: The infection antibody levels against porcine pseudorabies virus (PRV) were monitored in pigs at two intensive swine farms which immunicated with Bartha strain of PRV in Daxing and Shunyi districts of Beijing over a three-year period, combined with the clinical status of the farm and PCR assay result, the results indicated that there was a prevalence of pseudorabies in immunicated pigs in Beijing from 2011 to 2012. We should pay much attention to this situation. Causes needed further analysis by virus isolation and its molecular genetic analysis.

Key words: porcine pseudorabies virus; vaccine; eradication; antibody monitor
