Figure. Phylogenetic relationships of 2015 US Senecavirus A (SVA) isolates (SVA15-39812IA, SVA15-40380IA, SVA15-40381IA, and SVA15-41901SD) with the prototype SVA isolate (SVV-001), a 2011 Canada swine SVA isolate (11-55910-3), and 2015 Brazil swine SVA isolates (SVV-BRA-G03-2015, SVV-BRA-MG1-2015, and SVV-BRA-MG2-2015). A) Full-length genomic sequences of 4 isolates from Iowa and South Dakota (bold) compared with reference isolates. B) Viral protein 1 sequences of 4 isolates from Iowa and South Dakota and 6 additional sequences from Iowa, Illinois, and South Dakota (2015044256SD, 2015044662IA, 2015046008IA, 2015046494IL, 2015047169IA, and 2015047271IL) (bold) compared with reference isolates. Trees were determined by using the neighbor-joining method with 1,000 bootstrap replicates. GenBank accession numbers for reference isolates are provided in parentheses. Scale bars indicate nucleotide substitutions per site.
