Passive immunity to porcine epidemic diarrhea virus following immunization of pregnant gilts with a recombinant orf virus vector expressing the spike protein 2018-05-03 .txt text/plain 4281 210 54 PEDV NA, IgG and IgA were detected in the serum of piglets born to immunized gilts, demonstrating the transfer of antibodies through colostrum and milk. In the present study, we investigated the immunogenicity of ORFV-PEDV-S recombinant virus in pregnant gilts and its ability to induce passive immunity and protection in piglets born to immunized animals. Animals in G1 seroconverted to PEDV, presenting detectable levels of IgG, IgA and NA a week after challenge of the piglets (day 7 post-birth; Fig. 1 ). Notably, passive transfer of antibodies from gilts to piglets was observed in both G2 and G3, as PEDV-specific IgG, IgA and NAs were detected in serum of piglets born to immunized gilts following ingestion of colostrum and milk. Additionally, passive transfer of antibodies from gilts to piglets was observed, as PEDV-specific IgG, IgA and NAs were detected in serum of piglets born to immunized gilts following ingestion of colostrum and milk. ./cache/cord-272973-kzaowysv.txt ./txt/cord-272973-kzaowysv.txt
