Title: Efficacy of inactivated variant porcine epidemic diarrhea virus vaccines in growing pigs Document date: 2018_1_29
ID: w643jf90_4
Snippet: Recently, the highly virulent PEDV strain QIAP1401 was isolated from pooled intestinal homogenates and sequentially subjected to 70 passages in Vero cells in our laboratory. Phylogenetic analysis based on the full-length PEDV S gene revealed that the QIAP1401 strain belongs to the G2b genogroup and has a close phylogenetic relationship with the U.S. PEDV strains that emerged in 2014 [17] . In the present study, we developed an inactivated Korean .....
Document: Recently, the highly virulent PEDV strain QIAP1401 was isolated from pooled intestinal homogenates and sequentially subjected to 70 passages in Vero cells in our laboratory. Phylogenetic analysis based on the full-length PEDV S gene revealed that the QIAP1401 strain belongs to the G2b genogroup and has a close phylogenetic relationship with the U.S. PEDV strains that emerged in 2014 [17] . In the present study, we developed an inactivated Korean PEDV vaccine and assessed its efficacy against homologous PEDV challenge in growing pigs. Furthermore, various adjuvants were evaluated to determine the optimum vaccine-adjuvant mixture for inducing humoral immunity in pigs.
