With the established methods, 38 clinical samples from the respiratory disease pigs were detected for the presence of PCV2 and PRRSV. The results demonstrated that 22 samples were positive for PCV2, 27 samples were positive for PRRSV and among the above positive samples, 18 samples were positive for both viruses. The data obtained in the present study indicated that PCV2 and PRRSV maybe play an important role in the course of the development of respiratory diseases.展开更多
