Genetic Detection of Dobrava/Belgrade Virus, Bulgaria
Figure. Phylogenetic trees based on a 560-bp fragment of the small RNA segment (A) and a 224-bp fragment of the medium RNA segment (B) of hantaviruses. Hantaan virus (HTNV) was used as the outgroup. The numbers at the nodes indicate percentage bootstrap replicates of 100; values <60% are not shown. Horizontal distances are proportional to the nucleotide differences. Sequences in the tree are indicated as GenBank accession number, strain name, country. Strains from this study are shown in boldface. Scale bars indicate 10% nucleotide sequence divergence.
