Peptide ELISA results. Nine peptides named as VD-203-VD209 were coded on the plates with concentration 2ug/ml. Nine PRRSV positive sera from pigs with clear virus exposure history (I-CH-1A from pigs infected with PRRSV stain CH-1a, I-HuN4 from pigs infected with PRRSV stain HuN4 and C + H infected with these two strains), 3 standard positive sera (P1+, P2+ and P3+) and 3 standard negative sera (N4-, N5- and N6-) were reacted with the peptides. Each reaction has three well repeats and the reaction differences were show by the bars. Significant different were considered when p < 0.05
