genetic diversity and geographic distribution of hantaviruses in russia. | haemorrhagic fever with renal syndrome (hfrs) is the most prevalent zoonotic disease in russia. it is caused by several hantavirus species hosted by small rodents. we describe spatial and temporal patterns of hfrs incidence in the russian federation, and the geographic distribution of prevalent hantavirus species: puumala (puuv) and dobrava (dobv). partial sequencing of nucleocapsid and glycoprotein genes of 117 puuv strains and 78 dobv strains revealed several distinct genetic subgroups. the rn ... | 2009 | 19486318 |
[the virus carriage of ticks, vectors of the causative agent of crimean hemorrhagic fever]. | the study of ixodes ticks collected in astrakhan province in 1982-1987 has revealed spontaneous infection with crimean hemorrhagic fever virus in 4 species. it has been established that a proportion of the infected ck suspensions from the imago hyalomma marginatum marginatum (a back-ground species for the given region) was 3.6% as measured by the method of mouse infection and 8.9% as measured by the enzyme immunoassay. the advantages of the enzyme immunoassay as a method for crimean hemorrhagic ... | 1991 | 1829784 |
[detection of a new natural virus focus dobrava in the astrakhan region]. | a natural focus of dobrava hantavirus was first revealed in an arid zone of the astrakhan region, by using molecular genetic methods. a polymerase chain reaction was employed to examine 389 lung tissue suspension samples taken from 9 species. hantavirus rna was found in 35 samples from 22 field mice (apodemus agrarius), 8 tamarisk gerbils (meriones temariscinus), 4 common voles (microtus arvalis), and 1 house mouse (mus musculus). sequencing determined the taxonomic affiliation of 18 new isolate ... | 2008 | 18450108 |
[estimation of the cytogenetic homeostasis in natural populations of small murine rodents from the lower (astrakhan') and middle (chapaevsk) volga regions]. | frequencies of chromosomal aberrations were estimated in the bone marrow of two background small rodent species, the bank vole (clethrionomys glareolus) and the house mouse (mus musculus) from the middle (chapaevsk, samarskaya oblast) and lower (astrakhanskaya oblast) volga regions. the majority of chromosomal aberrations were chromatid deletions. in the studied species, cytogenetic disturbances were most prevalent in areas where the anthropogenic environmental pollution was maximum. the lowest ... | 1997 | 9480223 |
