Figure. Complete genome (A) and spike gene (B) phylogenetic analysis using the maximum likelihood method with the general time reversible (GTR) nucleotide substitution model. Green indicates Minnesota188 strain, red indicates North American INDEL strains, and blue indicates the remaining North American porcine epidemic diarrhea virus (PEDV) strains. Scale bar indicates percentage of dissimilarity between sequences. C) Spike gene alignment of first 70 aa). The consensus represents 114 sequences used in the analysis. PEDV prototype strain CV777, 2 American original and INDEL PEDV strains are illustrated. Dots indicate amino acid residues matching the consensus are represented by dots; dashes represent amino acid deletions.
