Core Tip
Core tip: Pseudorabies virus (PRV) variant HN1201 has pathogenicity in 35 to 127-d old pigs via intranasal inoculation at 107 TCID50. Intranasal inoculation is more efficient than intramuscular inoculation for PRV challenge. PRV variant HN1201 showed higher pathogenic ability, as shown by the more severe clinical symptoms, pathological lesions, and abundant antigen distribution in extensive organs than the classical PRV Fa strain.
