Figure 2From: Systemic and intestinal porcine epidemic diarrhea virus-specific antibody response and distribution of antibody-secreting cells in experimentally infected conventional pigsS/P ratios of PEDV IgG and IgA antibodies in serum and fecal samples serially collected from pigs inoculated with PEDV. Antibodies to PEDV in collected serum samples were detected by IgG (A) and IgA (B) ELISAs. Antibodies to PEDV in collected fecal samples were detected by IgA ELISA (C). *p < 0.05 and **p < 0.01 (significant and highly significant, respectively) determined using Dunnett's test. Cut-off values were the mean + three standard deviations of sample values at 0 dpi in infected pigs and negative controls. Solid line: PEDV-inoculated group. Dotted line: cut-off value.Back to article page
