猪繁殖与呼吸综合征与伪狂犬病混合感染的分子生物学快速诊断

Rapid Molecular Diagnosis of Concurrent Infection of Porcine Reproductive and Respiratory Syndrome and Pseudorabies

猪繁殖与呼吸综合征自1987年发现至今,已在世界大多数养猪国家和地区普遍存在[1,2].而伪狂犬病作为仅次于口蹄疫、猪瘟的危害养猪业的重要疫病，一直引起人们的高度重视[3,4].

According to the nucleotide sequences of Porcine Reproductive and Respiratory Syndrome Virus VR2332 strain and Pseudorabies virus shanghai strain provided in GenBank, two pairs of primers were designed to amplify the N gene of PRRSV by RT-PCR and Tk gene of PRV by PCR. As a result, a rapid molecular diagnosis with high specificity and accuracy was set up.The result indicated that PRRSV was detected from 11 out of 33 samples, PRV was detected from 9 out of 33 samples, and co-infection by PRRSV and PRV was confirmed in 8 samples, the rate of co-infection was at 24.2%.
