Abstract

An indirect porcine epidemic diarrhea virus (PEDV) anti-immunoglobulin (Ig) G ELISA based on the S1 portion of the spike protein was validated and compared with an indirect immunofluorescence assay. On field serum samples the diagnostic sensitivity of the S1 ELISA was 100%, the diagnostic specificity was 94% and the S1 ELISA showed no cross-reactivity with antibodies against other porcine coronaviruses. Colostrum samples (n = 133) were also tested for anti-PEDV IgG and IgA. The diagnostic sensitivity was 92% for IgG and 100% for IgA, and the diagnostic specificity was 90% for IgG and 99.4% for IgA. These data suggest that the S1 ELISA is a sensitive and specific test that could also be used to evaluate PEDV colostral immunity.
