Rabies infection among wild and domestic animals constitutes a well-known problem in Lithuania, but only one dog rabies virus isolate sequence (1992) from Lithuania was used in the European rabies virus phylogenetic analysis. The objective of this work was to determine nucleoprotein (N) gene sequences and genetically characterize the rabies virus isolates in order to learn which virus group (biotype) is circulating in reservoir species in Lithuania. Classical rabies virus isolate nucleoprotein (N) gene sequences from different parts of Lithuania were found to be closely related to each other and demonstrated nucleotide identity from 97.7 to 100% and could be placed in one lineage with 100% bootstrap support. All 12 sequences of raccoon dogs, red foxes, dogs and marten rabies viruses exhibited 97.7 - 99.0% identity to previously published sequences from Eastern parts of Poland, Estonia, Finland and the North-Eastern part of Russia. Phylogenetic analysis revealed that all Lithuanian strains belong to the North East Europe (NEE) group of rabies virus.
