Title: Isolation and identification of swine pseudorabies virus HLJ8 strain
Abstract: The disease was occurred on a pig farm in Heilongjiang in 2013,with large number of deaths of piglets accompanied by neurological symptoms.By detecting with PCR and viral isolation,apseudorabies virus(PRV)strain named HLJ8 was isolated.Further analysis showed that PRV gE sequence of HLJ8 strain was in a relatively independent clade with Chinese isolates from 2012,and with a homology from94%to 100% at amino acid level.BALB/c mice infected with high doses(1×103 PFU/mL)HLJ8strain were died,accompanied by typical PRV infection symptoms such as itchy skin.However,the pathogenicity of HLJ8 strain was slightly lower than PRV SC,a classical virulent strain.
