Antibody kinetics in the sera of piglets inoculated with the rescued viruses. a-i The antibody 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. Antibodies specific for PRRSV were detected using an IDEXX PRRS X3 ELISA kit, and the antibody level was expressed as a sample value/positive value (S/P) ratio. A ratio≥0.4 was regarded as seroconversion
