[puumala and dobrava viruses in the northeastern and central regions of bosnia].bosnia and herzegovina has been known as a highly endemic region for hantavirus infections for more than 50 years. previous studies have shown that at least two different hantaviruses, the murine dobrava (dob) and avricoline puumala (puu) viruses, each carried by a different rodent species, have been circulating in the area. however, there is little information on rodent population density fluctuations in bosnia over the past years as well as on the ratio of puumala to dobrava infection in human ...200315011464
hemorrhagic fever with renal syndrome caused by 2 lineages of dobrava hantavirus, russia.dobrava-belgrade virus (dobv) is a european hantavirus that causes hemorrhagic fever with renal syndrome (hfrs); case-fatality rates in balkan countries are as high as 12%. to determine causative agents, we examined 126 cases of dobv-associated hfrs in central and southern european russia. in central russia (lipetsk, voronezh, orel regions), outbreaks were caused by a dobv variant (dobv-aa) carried by apodemus agrarius. in southern russia (sochi district), where hfrs is endemic, hfrs cases were ...200818394280
co-circulation of three pathogenic hantaviruses: puumala, dobrava, and saaremaa in hungary.hantaviruses (bunyaviridae) cause hemorrhagic fever with renal syndrome (hfrs) in eurasia and hantavirus (cardio)pulmonary syndrome (hcps) in the americas. hfrs is caused by hantaan virus (htnv), seoul virus (seov), dobrava virus (dobv), saaremaa virus (saav), and puumala virus (puuv). of those, only htnv is not present in europe. in recent years, hantaviruses, described in other parts of europe, were also detected at various locations in hungary. to study the genetic properties of hungarian han ...200919856478
surveillance of hantaviruses in poland: a study of animal reservoirs and human hantavirus disease in subcarpathia.the first cluster of hemorrhagic fever with renal syndrome (hfrs) in poland was identified in 2007 in the subcarpathian region. the natural environment of this area is a key habitat for hantavirus vectors. the animal reservoir of existing human hfrs clusters was studied to assess the occurrence of viruses (including tula virus, puumala virus, and dobrava-belgrade virus) among rodents. we examined 70 suspected human cases with symptoms corresponding to the clinical picture of hfrs. serological an ...201424902039
[hantaviruses in germany: threat for zoo, pet, companion and farm animals?].hantaviruses are so-called "emerging" and "re-emerging" viruses because of the new and sudden nature of their appearance. human infections can lead to two distinct disease patterns, the haemorrhagic fever with renal syndrome and the hantavirus cardiopulmonary syndrome. all known human pathogenic hantaviruses are transmitted through rodent hosts. there are three rodent-associated hantaviruses in germany. the bank vole-associated puumala virus (puuv) is responsible for most of the human hantavirus ...201424511827
autochthonous dobrava-belgrade virus infection in eastern germany.a 21-year-old male patient from borna, saxony, in eastern germany, suffered from acute kidney injury (aki) and symptoms typical for a hantavirus infection. these symptoms included nausea, vomiting, abdominal pain, diarrhea, and acute renal failure. serological investigations by indirect igm and igg in-house elisas, commercial immunofluorescence and line assays, as well as chemiluminescence focus reduction neutralization assay confirmed an acute dobrava-belgrade virus (dobv) infection of the pati ...201524495905
[actual problems of hemorrhagic fever with renal syndrome].from 2000 to 2011 85 600 cases of hemorrhagic fever with renal syndrome (hfrs) were registered in russian federation. epidemically active foci of hfrs infection are located generally in temperate latitudes of the european part and the far east. in the far east regions whose fraction of all the hfrs disease cases in russia is around 2%, the causative agents of the infection are hantaan, amur, seoul hantaviruses, the natural reservoir for those are striped field mouse, korean field mouse and brown ...201323805652
dobrava-belgrade hantavirus from germany shows receptor usage and innate immunity induction consistent with the pathogenicity of the virus in humans.dobrava-belgrade virus (dobv) is a european hantavirus causing hemorrhagic fever with renal syndrome (hfrs) in humans with fatality rates of up to 12%. dobv-associated clinical cases typically occur also in the northern part of germany where the virus is carried by the striped field mouse (apodemus agrarius). however, the causative agent responsible for human illness has not been previously isolated.201222545121
dobrava-belgrade virus: phylogeny, epidemiology, disease.dobrava-belgrade virus (dobv) is an old world hantavirus that causes hemorrhagic fever with renal syndrome in humans. with a case fatality rate up to 12%, dobv infection is the most life-threatening hantavirus disease in europe. the virus was initially identified in the balkans, but the discovery of new endemic foci have expanded its recognized geographic range. the recent description of novel genetic variants with different degrees of pathogenicity have complicated its taxonomic analysis. the o ...201222659378
molecular diagnostics of hemorrhagic fever with renal syndrome during a dobrava virus infection outbreak in the european part of russia.a large outbreak of hemorrhagic fever with renal syndrome (hfrs) occurred in the winter of 2006-2007 in a region southeast of moscow in central european russia. of the 422 patients with hfrs investigated in this study, 58 patients were found to be infected by puumala virus, whereas as many as 364 were infected by dobrava-belgrade virus (dobv). early serum samples from 10 dobv-infected patients were used for nucleic acid amplification, which was successful for 5 patients. molecular analyses demon ...200919828747
central european dobrava hantavirus isolate from a striped field mouse (apodemus agrarius).dobrava virus (dobv) is a hantavirus that causes hemorrhagic fever with renal syndrome (hfrs) in europe. it is hosted by at least two rodent species, apodemus flavicollis and a. agrarius. according to their natural hosts they form the distinct genetic lineages dobv-af and dobv-aa, respectively. we have now established a dobv isolate named slovakia (sk/aa) from an a. agrarius animal captured in slovakia. the complete s and m and partial l segment nucleotide sequences of the new isolate were deter ...200515956394
dobrava hantavirus causes hemorrhagic fever with renal syndrome in central europe and is carried by two different apodemus mice species.in central europe, hemorrhagic fevers with renal syndrome (hfrs) in humans are caused by the hantavirus species puumala (transmitted by voles) and a second, hantaan-related species (transmitted by mice). the second virus could be identified as dobrava virus. to date, 19 clinical cases of dobrava infection have been found in germany and slovakia. all patients exhibited a mild/moderate clinical course and no case fatality occurred. screening for infected rodents revealed that the striped field mou ...200111170053
short report: simultaneous occurrence of dobrava, puumala, and tula hantaviruses in slovakia.the prevalence of antibody to hantaviruses in slovakia (serum panel n = 2,133) was lower in the western part (0.54%) and higher in the eastern part (1.91%) of the country and was found to be significantly enhanced in a group of forest workers from eastern slovakia (5.88%). one-third of the igm-negative convalescent phase sera from patients with hemorrhagic fever with renal syndrome exhibited antibodies reacting predominantly with puumala virus antigen, while two-thirds had antibodies directed ma ...199910497981
genetic evidence of dobrava virus in apodemus agrarius in hungary.using nested polymerase chain reaction, we sequenced dobrava virus (dob) from the rodent apodemus agrarius in hungary. the samples we isolated group with dob samples previously isolated from a. flavicollis. this grouping may indicate host switching.199910341190
[serological characteristics of hantaviruses from clinical specimens analyzed in 1998-2008 in the department of virology, public health institute, ostrava].in 1998 - 2008, serum samples from 464 patients, predominantly residents of the moravia-silesian region, were examined in the department of virology, public health institute in ostrava, using enzyme-linked immunosorbent assay (elisa) for the detection of specific anti-hantavirus antibodies. seropositivity was ascertained in 41 persons (8.8%). more patients tested seropositive against hantaan virus (24, i.e. 58.5%) than against puumala virus (13, i.e. 31.7%). four persons were reactive against bo ...200919750821
hantavirus disease in germany due to infection with dobrava-belgrade virus genotype kurkino.members of the dobrava-belgrade virus (dobv) species are hantaviruses carried by different apodemus mice as reservoir hosts and causing haemorrhagic fever with renal syndrome (hfrs) in humans. in central europe, the kurkino genotype of dobv, associated with the striped field mouse, apodemus agrarius, is prevalent. this paper presents the first extensive study of the serological and molecular diagnostics, epidemiology and clinics of dobv-kurkino infections in central europe. serum samples from 57 ...201424438436
genetic detection of dobrava-belgrade hantavirus in the edible dormouse (glis glis) in central serbia.hantaviruses are endemic in the balkans, particularly in serbia, where sporadic cases and/or outbreaks of hantaviral human disease have been reported repeatedly, and evidenced serologically. here, we present genetic detection of dobrava-belgrade virus (dobv) hantaviral sequences in wild rodents trapped in central serbia. all the animals were pre-screened serologically by indirect immunofluorescence (if) test and only those with a positive finding of hantaviral antigens were further tested by pol ...201524762257
dobrava-belgrade virus spillover infections, germany.we present the molecular identification of apodemus agrarius (striped field mouse) as reservoir host of the dobrava-belgrade virus (dobv) lineage dobv-aa in 3 federal states of germany. phylogenetic analyses provided evidence for multiple spillover of dobv-aa to a. flavicollis, a crucial prerequisite for host switch and genetic reassortment.200919961690
genetic interaction between distinct dobrava hantavirus subtypes in apodemus agrarius and a. flavicollis in nature.dobrava virus (dobv) occurs in two different rodent species, apodemus flavicollis (dobv-af) and a. agrarius (dobv-aa). we sequenced the s and m genomic segments from sympatric dobv-af and dobv-aa strains which fell into two distinct genetic lineages. molecular phylogenetic analyses gave evidence for genetic reassortment between s and m segments of dobv-af and dobv-aa and indicated homologous recombination events in dobv evolution. dobv-af and dobv-aa are distinct but also subject to genetic exch ...200312477889
first molecular identification of human dobrava virus infection in central europe.viral rna was amplified by reverse transcription-pcr from a patient suffering from hemorrhagic fever with renal syndrome (hfrs) in germany. the virus strain could be assigned to the dobrava hantavirus (dobv). this is the first molecular identification of human infection by dobv in central europe and the first proof that a virus strain related to the dobv-aa lineage, carried by apodemus agrarius rodents, is able to cause hfrs.200415004109
