We report here the complete genome sequence (GenBank KP997032) of rabies virus strain RABV/Ursus arctos/Russia/Primorye/PO-01/2014, isolated in November 2014 from a brown bear (Ursus arctos) that attacked a person in Primorsky Krai (Russian Federation). This strain was clustered into the Eurasian genetic subgroup of genotype 1 (street rage).

We sequenced part of the mitochondrial control region of 2 Himalayan Ursus arctos isabellinus individuals and compared it with that of other U. arctos. Results indicate that the valid allopatric subspecies U. a. isabellinus represents an ancient clade and includes the Gobi bear of Mongolia as a relict population.

Factors Affecting Fear of Local Communities Toward Brown Bears (Ursus arctos) in Kohgiluyeh and Boyer-Ahmad Province, Iran

The allelic diversity of the DRB locus in major histocompatibility complex (MHC) genes was analyzed in the brown bear (Ursus arctos) from the Hokkaido Island of Japan, Siberia, and Kodiak of Alaska. Nineteen alleles of the DRB exon 2 were identified from a total of 38 individuals of U. arctos and were highly polymorphic. Comparisons of non-synonymous and synonymous substitutions in the antigen-...

Although the American black (Ursus americanus) and American brown (grizzly) (Ursus arctos horribilis) bears have been the subjects of intensive physiological research, very little so far, has been done to understand the physiology of the European brown bear (Ursus arctos arctos). In our laboratory the research on the physiology of European brown bears started 10 years ago. Between 1987 and 1997...

Polar bears (Ursus maritimus) and brown bears (Ursus arctos) are closely related species for which extensive mitochondrial and nuclear phylogenetic comparisons have been made. We used previously published genotype data for 8 microsatellite DNA loci from 930 brown bears in 19 populations and 473 polar bears in 16 populations to compare the population genetic relationships of extant populations o...

Sequence analyses of the complete brown bear, Ursus arctos, mitochondrial DNA (mtDNA) genome have detected scattered single nucleotide polymorphisms (SNPs) that define distinct mtDNA haplogroups in phylogeographical studies. The degraded DNA in historical samples, such as stuffed or excavated specimens, however, is often not suitable for sequence analyses. To address this problem, we developed ...

Human contact with bears has become more frequent, as has the resultant bear maulings and bite injuries. We report the bacteriology of a patient bitten by a grizzly bear (Ursus arctos) from the Rocky Mountains foothills area east of Banff National Park, Alberta, Canada. The patient received field care, including metronidazole and cefazolin. Subsequent deep-wound cultures grew Serratia fonticola...
