Genomic Characterization and Pathogenicity of BJEU06-1-Like PRRSV-1 ZD-1 Isolated in China

Figure 1

Phylogenetic analysis of the nucleotide sequences of ORF5 of PRRSV-1 strains. Chinese PRRSV-1 isolates belong to subtype 1 (global) and can be divided into four subgroups (Amervac-like, BJEU06-1-like, HKEU16-like, and NMEU09-1-like). Recently obtained Chinese PRRSV-1 sequences in our lab are represented by blue squares (■). The ZD-1 isolate from this study is indicated by a red star (★). Two Chinese PRRSV-1 isolates, HLJB1 and GZ11-G1, used in the pathogenicity evaluation are labeled with red triangles (▲).
