A phylogenetic tree of rabies virus sequences generated from specimens infected with south central skunk variant. A neighbor joining analysis was performed on nucleoprotein gene sequences. Sequences from two raccoon virus variant samples were included as an out group. Samples are identified by their state of origin, animal species, and year of isolation (KSSK11 indicates a skunk from Kansas in 2011). The viral isolate recovered from the second bison in this account is shown in red, while 2 other isolates from Colorado appear in blue. A distance scale is shown at bottom left.
