[44]Similarity plot analysis using IA70388-R (recombinant) strain of PRRSV as the query sequence against IA76950-WT (wt, blue line) strain and an attenuated live vaccine-like strain (green line). A recombination breakpoint is shown with a purple dotted line and the location is underscored at the nucleotide site. Back to article page
