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 ...200616629984
pathology and viral distribution in fatal usutu virus infections of birds from the 2001 and 2002 outbreaks in austria.in the summer of 2001, usutu virus (usuv) was isolated for the first time in europe, from an episode of mass mortality in eurasian blackbirds (turdus merula). in the present study, 40 of the birds (representing three species), confirmed as cases of usuv infection, were examined by four methods (histopathology, immunohistochemistry [ihc], in-situ hybridization [ish] and reverse-transcriptase polymerase chain reaction [rt-pcr]). the major macroscopical finding was hepatosplenomegaly; histologicall ...200415276857
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 ...200818314208
monitoring of usutu virus activity and spread by using dead bird surveillance in austria, 2003-2005.usutu virus has been causing avian mortality in austria since its emergence in 2001. between 2003 and 2005 a total of 504 dead birds were examined by reverse-transcriptase polymerase chain reaction and immunohistochemistry for the presence of usutu virus nucleic acid and antigen, respectively. in 2003, 92 birds (out of 177 birds) belonging to five different species were positive, while in 2004, only 11 (of 224) birds, and in 2005, 4 (of 103) birds proved positive, all of which were blackbirds (t ...200717346908
limited pathogenicity of usutu virus for the domestic chicken (gallus domesticus).in summer 2001, usutu virus (usuv), a mosquito-borne flavivirus, was isolated for the first time in europe during a mortality incident among eurasian blackbirds (turdus merula) in austria. chickens are frequently used as sentinel animals for arbovirus surveillance systems. in the present study, the pathogenicity of usuv for specific pathogen free chickens was investigated. ten 2-week-old chickens were inoculated intravenously with 0.1 ml inoculum containing 10(3) median (50%) tissue culture infe ...200516236570
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 ...200717913929
simulation of climate-change scenarios to explain usutu-virus dynamics in austria.the emergence and spread of infectious diseases in mid-latitudes, so far mainly observed in the tropics, considerably increase under the current situation of climate change. a recent example is the usutu virus (usuv) outbreak in austria. usuv is closely related to the west nile virus in the u.s. and caused mass mortalities mainly of blackbirds (turdus merula). the usuv flavivirus persists in a natural transmission cycle between vectors (mosquitoes) and host reservoirs (birds) and leads - once en ...200918715663
