Figure 3From: Cross protective immune responses in nursing piglets infected with a US spike-insertion deletion porcine epidemic diarrhea virus strain and challenged with an original US PEDV strain PEDV specific antibody responses of sows in serum and milk whey. Sow serum (A) and milk whey (B) virus neutralization antibody titers were quantified by plaque reduction virus neutralization assay. Sow serum (C) and milk whey (D) PEDV specific IgA antibody responses were quantified by ELISA.Back to article page
