Phylogenetic tree based on ORF2 (a) and genome (b). Phylogenetic trees were constructed with the MEGA 7.0.14 software using the neighbor-joining (NJ) method, with the Jukes-cantor model as a nucleotide substitution model. The reliability of the generated trees was determined with 1000 replicates of the data set. 37 isolates and 19 reference sequences were used for this analysis. The isolations detected in this study were labeled by the red star, and reference strains downloaded from NCBI weren’t labeled
