Phylogenetic relationships among the PRRSV isolates. Homologous identity among the PRRSVs is shown in panel a. The isolate names and isolate places are provided; sequence alignment at the amino acid level in the N region of the PRRSVs is shown in panel b. The majority sequence shown at top is the consensus sequence, and four amino acid changes between the NA prototype strain VR2332 and the HH08 isolate are boxed. Using the MEGALIGN program in DNASTAR with the Jotun Hein method, a constructed phylogenetic tree is shown in panel c. The isolate names, GenBank accession numbers, and isolation places are indicated.
