  Fig. 1. Geographical distribution and PCV2 test results of clinical tissue samples in Henan province from 2015 to 2018. The first number in parentheses represents the total number of samples detected in this area, and the latter number represents the number of PCV2 positive samples detected in this area. The map in this figure is my own

  Fig. 2. 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

  Fig. 3. Sequence alignment of multiple sequence amino acids in PCV2 Cap protein. This alignment included deduced amino acid sequences of ORF2 from 37 PCV2 isolates and 15 PCV2 reference strains. The diagram was plotted by EPSprint 3.0. The antibody recognition domains (A (51–81), B (113–134), C (161–208) and D (228–233)) and immunodominant decoy epitope E (168–180), were demarcated by the colored boxes, in bright green, blue, white, black and dark red, respectively
