Genome recombination analysis of the IA70388-R strain of porcine reproductive and respiratory syndrome virus, United States, 2018. A) UPGMA of region derived from major parent (1–6742). B) UPGMA of region derived from major parent (6743–15642 nt). Phylogenies of the parent strains were identified using RDP version 4.24 software (http://web.cbio.uct.ac.za/~darren/rdp.html). Red indicates the recombinant (IA70388-R); green indicates the major parent strain (the Fostera vaccine strain); blue indica
