Resistance to Virulent PRV Latency by PR Gene-deleted Vaccine SA215;

In this study,a pig pseudorabies virus(PRV)-latency model was established by vaccinating PRV-free piglets with commercial PRV inactivated vaccine,followed by challenge with a genetically marked PRV strain gG-/LacZ+.

Meanwhile, the regular sites where pseudorabies virus virulent strains established latency were determined to be trigeminal ganglion.
