Figure
Figure. Phylogenetic tree of the whole-genome sequences of 33 strains of porcine epidemic diarrhea virus (PEDV) (A) and of spike protein nucleotide sequences of 56 strains of PEDV (B), including the new variant PEDV (OH851) and 8 PEDV strains currently circulating in the United StatesThe dendrogram was constructed by using the neighbor-joining method in MEGA version 6.05 (www.megasoftware.net)Bootstrap resampling (1,000 replications) was performed, and bootstrap values are indicated for each nodeReference sequences obtained from GenBank are indicated by strain name and accession numberScale bars indicate nucleotide substitutions per site.
