Figure. Dendrogram of Old World hantaviruses (upper, left, and lower part of the tree) vs. New World hantaviruses (right part of the tree). Reproduced with permission (42). Branch lengths are proportional to genetic distances. The bootstrap support percentages of particular branching points calculated from 500 replicates are given in ovals. HTN = Hantaan virus, strain 76-118; SEO = Seoul virus, strain SR-11; DOB = Dobrava virus, PH = Prospect Hill virus; TUL = Tula virus, strains Tula/76Ma/87, Moravia/5286Ma/94 and Malacky/Ma32/94; ILV = Isla Vista virus, strain MC-SB-1; TOP = Topografov virus; PUU = Puumala virus, strains Sotkamo, Vindeln/83-L20 and Udmurtia/458g/88; RIOS = Rio Segundo virus, strain RMx-Costa-1; ELMC = El Moro Canyon virus, strain RM-97; BAY = Bayou virus, strain Louisiana; BCC = Black Creek Canal virus; SN = Sin Nombre virus, strain H10; NY = New York virus, strain RI-1; KBR = Khabarovsk virus, another PUU-like virus, is not depicted here. PH & ILV (and BLL, not depicted here) are the only New World genotypes with PUU-like characteristics, hence their position close to the TUL-clade.
