Figure. Phylogenetic relationships among 27 arenaviruses isolated from rodents captured on Hato Maporal, Portuguesa State, Venezuela, 1994 or 1997; Guanarito virus (GTOV) prototype strain INH-95551 (boldface); and Pirital virus (PIRV) prototype strain VAV-488 (boldface) based on a neighbor-joining analysis of nucleocapsid protein gene sequence data. Branch lengths are proportional to genetic (p) distances; the numbers at the nodes indicate the percentage of 1,000 bootstrap replicates that supported the interior branches; bootstrap support values <70% are not listed; and the analysis was rooted to Oliveros virus strain 3229–1 (GenBank accession no. NC_010248). The branch labels include (in the following order) virus strain, host species, year of isolation, and (viruses from 1997) the study site at which the infected rodent was captured.
