Virus isolation and identification of the PEDV S-INDEL strain EJS6. A RT-PCR was conducted to detect the presence of PEDV, PDCoV, TGEV, and PoRV in the collected intestinal samples. M: 2,000 bp DNA marker; lane 1: PEDV; lane 2: PDCoV; lane 3: TGEV; lane 4: PoRV. B Identification of EJS6 in Vero cells via indirect immunofluorescence assay using a PEDV N-specific mAb. The fluorescence images were captured via a fluorescence microscope (Olympus). Scale bars, 100 μm
