Abstract: 
Arenaviruses are enveloped viruses with a genome composed of two ssRNA species, designated L and S. The arenaviruses were divided in two major groups (Old World and New World), based on serological properties and genetic data, as well as geographic distribution. A sequence alignment analysis of all reported arenavirus S RNAs yielded 17 conserved regions in addition to a reported conserved region at the end of both RNAs. The consensus sequences of these regions were used to design generalized primers suitable for RT-PCR amplification of a set of overlapping nucleotide sequence fragments comprising the complete S RNA of any arenavirus. A restriction analysis (RFLP) was designed to rapidly typify the amplified fragments. This RT-PCR-RFLP approach was tested with Old World (LCM) and New World (Junin and Tacaribe) arenaviruses. Furthermore, using this procedure the whole S RNA of a novel arenavirus isolate obtained from a rodent trapped in central Argentina, was amplified and characterized. Partial nucleotide sequence data were used for phylogenetic analyses that showed the relationships between this arenavirus and the rest of the members of the family. This relatively simple methodology will be useful both in basic studies and epidemiological survey programs.
