| phylogeny of new world arenaviruses based on the complete coding sequences of the small genomic segment identified an evolutionary lineage produced by intrasegmental recombination. | previous studies suggested that the small genomic segments (s-rna) of the south american arenaviruses (sa-avs) represent three phylogenetic lineages (designated a, b, and c) and indicated that the s-rna of whitewater arroyo virus (wwav) (a north american arenavirus [na-av]) is a product of genetic recombination between a lineage a and lineage b virus. the purpose of this study was to extend our knowledge on the phylogenetic relationships between wwav, the two other na-avs (tamiami and bear canyo ... | 2002 | 12207889 |
