Abstract: The piglets were diagnosed as co-infection of PRRSV and HEV by clinical symptoms, serological assay, pathological observation, animal experiment and RT-PCR in a large scale pig farm in Liaoning province. The results of RT-PCR showed that the isolated PRRSV was American stain, and most PHEV infections were clinically inapparent. The co-infection of PRRSV and PHEV maybe related to decreased immunity which caused by PRRSV.
