Phylogenetic analyses of the P1-encoding (1AB-1D) (A) and the 3CD-encoding (B) gene regions of 65 picornavirus strains. Sixty-four sequences obtained from the GenBank and the EPV-1 sequence were included. The tree was inferred with MrBayes 3.1.2 using the GTR substitution model assuming gamma distribution and invariant sites. GenBank accession numbers, (tentative) species names, and strain designations are presented. The scale bar indicates substitutions per site. Numbers at nodes indicate posterior probabilities.
