Development and application of an indirect ELISA for the detection of antibodies to porcine epidemic diarrhea virus based on a recombinant spike protein

Table 3 Detection rates of anti-PEDV antibodies in field serum samples

PEDV exposure	PoRV/TGEV exposure	No. samples	No. positive	Positive rate
Exposed	Non-exposed	1125	1027	91.29%
Non-exposed	Non-exposed	482	31	6.43%
Non-exposed	Exposed	149	16	10.74%
Non-exposed	Exposed	195	27	13.85%
Unknown	Unknown	1353	491	36.29%

Samples were collected from farms with known or unknown PEDV exposure as determined by real-time RT-PCR of fecal samples
