Fig. 1From: Efficacy of genogroup 1 based porcine epidemic diarrhea live vaccine against genogroup 2 field strain in JapanCell culture and phylogenetic analysis of PEDV MZ0116-2/2013 strain. a CPE of MZ0116-2/2013 in Vero cells. Vero cells were infected with PEDV MZ0116-2 P5 isolates. At 48 h post-infection, CPE was recorded. b Phylogenetic tree based on the spike gene sequence of PEDV field isolates. Bootstrap values are represented at key nodes. Scale bar indicates nucleotide substitutions per site. The name of the strains and GenBank accession are shown.
