(A) Phylogram rooted to DOBV strain East Slovakia-856-Aa. Sequences were aligned in reference to nucleotide positions 720 to 1041 of the DOBV-Af type strain (GenBank accession number L41916). Branch distances correspond to sequence divergence. The GenBank accession numbers of the sequences used for the phylogram are (respectively, from top to bottom) AJ578082, AJ578081, AF442623, AF442622, DVI410619, DVI410615, and AJ269554, L41916, AJ009773, AJ009775, AJ131673, AJ131672, AF085336, AF085337, AJ269550, and AJ269549). *, sequence obtained in this study from M. musculus; **, sequence obtained in this study from A. sylvaticus. Country abbreviations are according to the international traffic code and precede the strain designations. The percent identities of the sequences in the DOBV-Af group to the original DOBV type strain are as follows: Cz Boletice 126, 99.1%; Cz Boletice 11, 98.8%; SK Slovakia-400-Af, 94.7%; GR DOBV/Ano-Poroia/AfI9/1999, 95.7%; GR DOBV/Ano-Poroia/13Af/1999, 96%; RUS As-1/Goryachiy Klyuch-2000, 90.4%; RUS P-s1223/Krasnodar-2000, 90.4%.
