Erratum to: Immunogenicity and antigenic relationships among spike proteins of porcine epidemic diarrhea virus subtypes G1 and G2

Erratum to: Arch Virol DOI 10.1007/s00705-015-2694-6

In the original publication, Table 2 was overlooked by the author during proof checking. The correct version of Table 2 is given below:

Table 2.

The luminescence intensity of fluorescence of anti-S polyclonal antibodies against different types of virus

	Dilution of anti-CV777 S polyclonal antisera
	1600	3200	6400	12800	25600	51200	102400
CV777	+++	+++	++	++	+	+	-
LNCT2	+++	+++	++	++	+	-	-
Vero E6	-	-	-	-	-	-	-

	Dilution of anti-LNCT2 S polyclonal antisera
	1600	3200	6400	12800	25600	51200	102400
LNCT2	+++	+++	++	++	+	+	-
CV777	+++	+++	++	++	+	-	-
Vero E6	-	-	-	-	-	-	-

The luminescence intensity was divided into four degrees: (+++) strong, (++) moderate, (+) weak and (-) negative

Also, the text in page 7 should read as below:

The average titer of anti-SLNCT2 PAbs neutralizing CV777 reached 1:230, while the titer of neutralizing LNCT2 was 1:387.
