Neutralizing antibody (NA) kinetics in the sera of piglets inoculated with the rescued viruses. a-i The NA kinetics of piglets inoculated with rHuN4-F112, rHuN4-F112-C1a, rHuN4-F112-C1b, rHuN4-F112-C27, rCH-1R, rCH-1R-H1a, rCH-1R-H1b, or rCH-1R-H27 or the MARC-145 cell culture supernatant, respectively. The NA titers of the experimental group serum samples against the inoculated rescued virus strains were calculated. The NA titers of the control group serum samples against rHuN4-F112 and rCH-1R were also calculated. The neutralization tests of each serum sample were repeated three times independently. The results represent the average of the duplicates
