| 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 ... | 2007 | 17346908 |
| 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 ... | 2009 | 18715663 |
| 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 |
