*Numbers above and below the diagonal are the nonidentities among the glycoprotein precursors and nucleocapsid proteins, respectively.
†BBTV, Big Brushy Tank virus strain AV D0390174 (GenBank accession no. EF619035); BCNV, Bear Canyon virus strain AV A0070039 (AY924391); CTNV, Catarina virus strain AV A0400135 (DQ865244); SKTV, Skinner Tank virus strain AV D1000090 (EU123328); TAMV, Tamiami virus strain W 10777 (AF512828); TTCV, Tonto Creek virus strain AV D0150144 (EF619033); WWAV, Whitewater Arroyo virus strains AV 9310135 (AF228063), AV 96010024 (EU123331), AV 96010151 (EU123330), and AV D1240007 (EU123329). The results of a previous study indicated that AV 96010024, AV 96010151, and AV D1240007 are strains of WWAV or strains of arenaviruses that are phylogenetically closely related to WWAV (5). Nonidentities among the amino acid sequences of the glycoprotein precursors and among the amino acid sequences of the nucleocapsid proteins of AV 9310135, AV 96010024, AV 96010151, and AV D1240007 in this study ranged from 16.0% to 25.8% and 7.3% to 10.3%, respectively.
