Residual plot of average physicochemical properties for GI isolates (Ishikawa, JEV28 and JEV45) in reference to SA14-14-2. Analyses were performed using PHYSICO [17] and PHYSICO2 [18] programs with an input of E proteins of SA14-14-2, Ishikawa, JEV28 and JEV45 in FASTA format. Percentile difference for each property was computed against the reference data and plotted using SYSTAT Sigma Plot v11.0
