MDBK cells were infected with H2O2 inactivated BVDV NADL. A Cell status after infection with BVDV. NC, normal MDBK cells; PC, positive control; 3%, MDBK cells were infected with BVDV inactivated by 3% H2O2 at 27℃ for 2 h; 7%, MDBK cells were inoculated with BVDV inactivated by 7% H2O2 at 27℃ for 2 h. The photo was taken with an inverted microscope from Shanghai Optical Instrument Factory, with a magnification of 400 × . B TCID 50 results of MDBK cells inoculated with BVDV NADL. C PCR result of 5’-UTR gene in cell culture. M, DL 500 DNA Marker; NC, negative control; NM, normal MDBK cell; PC, positive control; 3%, cells inoculated with H2O2 inactivated virus
