ABSTRACT
An attack of a brown bear (Ursus arctos) on human was detected in November, 2014 in the Barabash village (Khasan region of the Primorski krai) located in close proximity to the national park Land of the Leopard. The bear was shot. The deviant behavior of the bear indicated the possibility of rabies. The diagnosis was confirmed by means of laboratory methods. The strain RABV/Ursus arctos/Russia/Primorye/PO 01/2014 (further PO 01) was isolated from the brain of the bear. PO 01 is the first completely sequenced Far Eastern strain of RABV. It can be considered as topotypic. PO 01 considerably differs from the vaccine strain RV 97 (GenBank EF542830) that is the basis of attenuated vaccine applied in the Land of the Leopard. At the same time, the immunodominant sites in PO 01 and RV 97 proteins differ slightly. It can be recommended to continue application of the vaccine. The analysis of the PO 01 genome (GenBank KP997032) revealed its belonging to the Eurasian genetic subgroup of the genotype 1 (street rage). Thus, this genetic subgroup stretches to the East. Expansion of the cross-border protected territories of Russia and China in the Far East demands the correct statistics of circulation of the lyssaviruses to be kept.
