| complete genome analysis and molecular characterization of usutu virus that emerged in austria in 2001: comparison with the south african strain saar-1776 and other flaviviruses. | here we describe the complete genome sequences of two strains of usutu virus (usuv), a mosquito-borne member of the genus flavivirus in the japanese encephalitis virus (jev) serogroup. usuv was detected in austria in 2001 causing a high mortality rate in blackbirds; the reference strain (saar-1776) was isolated in 1958 from mosquitoes in south africa and has never been associated with avian mortality. the austrian and south african isolates exhibited 97% nucleotide and 99% amino acid identity. p ... | 2004 | 15464850 |
| limited pathogenicity of usutu virus for the domestic goose (anser anser f. domestica) following experimental inoculation. | usutu virus (usuv) is a mosquito-borne flavivirus of the japanese encephalitis virus group, which has been associated with avian mortality in austria since 2001. the affected birds are predominantly eurasian blackbirds (turdus merula). in the present study, the pathogenicity of usuv for domestic geese (anser anser f. domestica) was investigated. eleven 2-week-old geese were inoculated intramuscularly with 5 x 10(4) 50% tissue culture infectious dose of usuv strain vienna-2001 blackbird. no clini ... | 2006 | 16629984 |
| emergence of usutu virus in hungary. | in 2001, usutu virus (usuv), a mosquito-borne flavivirus of the japanese encephalitis virus serogroup related to west nile virus and previously restricted to sub-saharan africa, emerged in wild and zoo birds in and around vienna, austria. in order to monitor the spread of the infection, a dead bird surveillance program was established in austria and in neighboring hungary. in hungary, 332 dead birds belonging to 52 species were tested for usuv infection between 2003 and 2006. in the first 2 year ... | 2007 | 17913929 |
| explaining usutu virus dynamics in austria: model development and calibration. | usutu virus (usuv), a flavivirus of the japanese encephalitis virus complex, was for the first time detected outside africa in the region around vienna (austria) in 2001 by weissenböck et al. [weissenböck, h., kolodziejek, j., url, a., lussy, h., rebel-bauder, b., nowotny, n., 2002. emergence of usutu virus, an african mosquito-borne flavivirus of the japanese encephalitis virus group, central europe. emerg. infect. dis. 8, 652-656]. usuv is an arthropod-borne virus (arbovirus) circulating betwe ... | 2008 | 18314208 |
| usutu virus: an emerging flavivirus in europe. | usutu virus (usuv) is an african mosquito-borne flavivirus belonging to the japanese encephalitis virus serocomplex. usuv is closely related to murray valley encephalitis virus, japanese encephalitis virus, and west nile virus. usuv was discovered in south africa in 1959. in europe, the first true demonstration of circulation of usuv was reported in austria in 2001 with a significant die-off of eurasian blackbirds. in the subsequent years, usuv expanded to neighboring countries, including italy, ... | 2015 | 25606971 |
| epidemic spread of usutu virus in southwest germany in 2011 to 2013 and monitoring of wild birds for usutu and west nile viruses. | mosquito-borne viruses are becoming an increasing threat for europe. one of these viruses is usutu virus (usuv), a single-stranded rna virus belonging to the japanese encephalitis virus group within the family flaviviridae. since the occurrence of usuv among wild birds in june, 2011, infected blackbirds (turdus merula) have frequently been found dead in southwest germany, cumulating in a massive die-off. moreover, other bird species (strigiformes) in this region have been affected. in a first st ... | 2015 | 26273809 |
