Phylogeny and evolution of old world arenaviruses.
The intention of this study was to investigate the genomics, phylogeny and evolution of the Old World arenaviruses based on sequence data representing the four viral genes. To achieve this aim, we sequenced the complete S and L RNA segments of Ippy virus (IPPYV), Mobala virus (MOBV) and Mopeia virus (MOPV). Full-length sequences of the NP, GPC, Z and L genes were used to reconstruct phylogenetic relationships and to compare resulting tree topologies. Each of the five Old World arenavirus species (namely Lassa virus [LASV], IPPYV, MOBV, MOPV and Lymphocytic choriomeningitis virus [LCMV]) are monophyletic; seven selected strains of LASV showed a similar topology regardless of the gene under analysis; IPPYV rooted the three other African arenaviruses; the four African arenaviruses are rooted by the ubiquitous LCMV; and the tree topologies of the three African arenaviruses other than LASV are identical regardless of the gene used for analysis. No evidence for significant evolutionary events such as intra- or intersegmental recombination was obtained.
