Figure 2From: Increased frequency of porcine epidemic diarrhea virus shedding and lesions in suckling pigs compared to nursery pigs and protective immunity in nursery pigs after homologous re-challenge Anti-PEDV IgA (A) and IgG (B) antibodies levels in serum of PEDV infected pigs. Serum samples were collected from PEDV infected pigs at dpi 0 and dpi 14. Pigs infected with PEDV at 10 days of age are indicated by white bars and pigs infected with PEDV at 8 weeks of age are indicated by grey bars. Data are presented as mean ELISA S/P ratios. The asterisk indicates a significant difference in group mean S/P ratios.Back to article page
