Characterization of the recombinant PRRSV strains rBB20s, rBB20s/GP2, rBB20s/GP3, rBB20s/GP4, rBB20s/M and revertant virus rBB20s/M-R. a Plaque morphology assay. b Virus neutralization assays of recombinant viruses by using the N4 serum. c The growth kinetics. The data are represented as the means ± s.d. of three independent experiments, and significant differences are shown (*P < 0.05 and **P < 0.01) by using one-way analysis of variance (ANOVA)
