Detection of antigenicity difference between the epizootic varIBDV (SHG19 strain) and vvIBDV (HLJ0504 strain and Gx strain). (A) Cross-neutralizing assay of HLJ0504 antiserum for SHG19 and HLJ0504 on DT40 cells directed. (B) Cross-neutralizing assay of SHG19 antiserum for SHG19 and HLJ0504 on DT40 cells directed. (C) IFA on DT40 cells directed by MAbs 2-5C-6F and 7D4. The mean titers and standard deviations (error bars) from three (A) or five (B) independent samples are shown. * represents p < 0.05.
