Abstract: PED was suspected to have occurred in a pig farm in Jiangsu Province, and after collection of disease material, PEDV was tested positive by RT-PCR. Virus-infected Vero cells were able to cause significant cytopathic changes, and the immunofluorescence results showed that the virus-infected cells could be recognized by a specific monoclonal antibody against PEDV N protein. Through whole genome sequence analysis, this strain was identified as a PEDV G2b subtype variant and designated PEDV JS-B strain.

Key words: porcine epidemic diarrhea virus, isolation and identification, variant strain, segmental sequencing, sequence analysis
