| molecular evolution of puumala hantavirus in fennoscandia: phylogenetic analysis of strains from two recolonization routes, karelia and denmark. | like other members of the genus hantavirus: in the family bunyaviridae:, puumala virus (puuv) is thought to be co-evolving with its natural host, the bank vole clethrionomys glareolus. to gain insight into the evolutionary history of puuv in northern europe during the last post-glacial period, we have studied wild-type puuv strains originating from areas along two postulated immigration routes of bank voles to fennoscandia. full-length sequences of the s rna segment and partial sequences (nt 216 ... | 2000 | 11086113 |
