First molecular evidence of Tula hantavirus in Microtus voles in Slovenia.

Different Microtus species, present in a worldwide range habitat populating North America, Europe, Asia, and few other species have been recognized previously as a hantavirus reservoir. Tula hantavirus was first reported in Microtus arvalis and Microtus rossiaemeridionalis from Central Russia and later discovered in several European countries. Using molecular techniques we have demonstrated the presence of Tula hantavirus in three different Microtus species in Slovenia. Phylogenetic analyses of partial S segment placed Slovenian strains in the same genetic lineage as Austrian and Croatian strains.
