Phylogenetic tree generated by the Bayesian method, under the best-fit GTR+I+Γ model of evolution, based on the L-genomic segment of SWSV and other well-characterized hantaviruses. The phylogenetic positions of SWSV variants from Finland and Hungary are shown in relationship to SWS (Seewis) mp70 (EF636026) from the Eurasian common shrew (Sorex araneus), ARR (Ash River) MSB73418 (EF619961) from the masked shrew (Sorex cinereus), JMS (Jemez Springs) MSB144475 (FJ593501) from the dusky shrew (Sorex monticolus), CBN (Cao Bang) CBN-3 (EF543525) from the Chinese mole shrew (Anourosorex squamipes), RPL (Camp Ripley) MSB89863 (EF540771) from the northern short-tailed shrew (Blarina brevicauda), TPM (Thottapalayam) VRC66412 (EU001330) from the Asian house shrew (Suncus murinus), MJN (Imjin) Cl05-11 (EF641806) from the Ussuri white-toothed shrew (Crocidura lasiura), ASA (Asama) N10 (EU929078) from the Japanese shrew mole (Urotrichus talpoides), OXB (Oxbow) Ng1453 (FJ593497) from the American shrew mole (Neurotrichus gibbsii), and NVA (Nova) MSB95703 (FJ593498) from the European common mole (Talpa europaea). Also shown are representative rodent-borne hantaviruses, including HTN (Hantaan) 76-118 (NC_005222), SOO (Soochong) SOO-1 (DQ056292), DOB (Dobrava) Greece (NC_005235), SEO (Seoul) 80-39 (NC_005238), TUL (Tula) 5302v (NC_005226), PUU (Puumala) Sotkamo (NC_005225), PH (Prospect Hill) PH-1 (EF646763), SN (Sin Nombre) NMH10 (NC_005217), and AND (Andes) Chile9717869 (NC_003468). GenBank accession numbers for the L-segment sequences of SWSV strains are GQ293099, GQ293100, GQ293101, GQ293102, GQ293103, GQ293108, GQ293109, GQ293110, GQ293111, GQ293112, GQ293113, GQ293114 for Finland; and GQ293097, GQ293098, GQ293106, GQ293107, GQ293115, GQ293116, GQ293117, GQ293118, GQ293119, GQ293120, GQ293121, GQ293122, GQ293123 for Hungary. For the S-segment sequences of SWSV strains, GenBank accession numbers were GU186445, GQ293125, GU186444, GQ293126, GQ293129, GQ293130, GQ293131, GQ293132, GQ293133, GQ293134 for Finland; and GQ293124, GU186442, GQ293127, GQ293128, GU186443, GQ293135, GQ293136, GQ293137, GQ293138 for Hungary. The numbers at each node are posterior node probabilities based on 30,000 trees: two replicate Markov Chain Monte Carlo runs consisting of four chains of two million generations each sampled every 100 generations with a burn-in of 5,000 (25%). The scale bar indicates nucleotide substitutions per site.
