Nonidentities (p-model distances) between the nucleotide sequences of the Z genes and between the nucleotide sequences of a fragment of the RNA-dependent RNA polymerase (RdRp) genes are listed above and below the diagonal, respectively.
The strains of Guanarito virus from humans included the prototype strain INH-95551 and strains CVH-950801, CVH-960101, CVH-960102, CVH-960103, CVH-960302, CVH-961104, and S-56764. Guanarito virus strains AV 97021119, VHF-1608, VHF-3990, and VHF-1750 were from short-tailed cane mice captured in Portuguesa, Apure, Cojedes, and Guárico, respectively. Pirital virus strains VAV-488 and AV 97021016 and strains 1645, 3945, and 1743 were from Alston’s cotton rats captured in Portuguesa and Apure, Cojedes, and Guárico, respectively.
Nonidentities between the nucleotide sequences of the Z genes and between the nucleotide sequences of the RdRp gene sequences of the 8 Guanarito virus strains from humans ranged from 0.0 to 7.4% and from 0.0 to 5.6%, respectively.
