emergence and establishment of usutu virus infection in wild and captive avian species in and around zurich switzerland genomic and pathologic comparison to other central european outbreaks
Veterinary Microbiology, 2011Co-Authors: Hanspeter W Steinmetz, Tamas Bakonyi, Ulrike Eulenberger, Nadia Robert, Richard K Hoop, Jean-michel Hatt, Herbert Weissenböck, Norbert NowotnyAbstract:In late summer 2006 considerable mortality in wild and captive Passeriformes and Strigiformes was observed in Zurich, Switzerland. All animals were found in a range of 2km(2). Observed clinical signs involved depression, ruffled plumage, incoordination, seizures and peracute death. Nutritional status was generally moderate to poor in wild birds, and variable in captive animals. Necropsy showed marked splenomegaly, a mild hepatomegaly, and pulmonary hyperemia in most animals. Histopathologic lesions were very discrete and consisted mainly of neuronal necrosis, leucocytolysis in and around the brain blood vessels, and miliary liver necrosis. The diagnosis Usutu virus (USUV) infection was established by USUV-specific immunohistochemistry and reverse transcription-polymerase chain reaction. Partial nucleotide sequence comparisons revealed>99% identity between the viruses that emerged in Zurich in 2006, in Vienna in 2001, and in Budapest in 2005. Since 2008 a significantly lower mortality was observed in wild Passeriformes, but USUV infection was confirmed for the first time beyond Zurich city limits. Indoor housing and regular treatment against ectoparasites are likely to have prevented acute USUV disease in captive Strigiformes. USUV is a mosquito-borne flavivirus causing fatalities in various avian species. After the initial European outbreaks in Austria in 2001 it appears that the virus has extended its range in Central Europe and has established a transmission cycle between local bird and mosquito species. Further episodes of increased avian mortality in the forthcoming years, with impact on wild and captive bird populations, predominantly Passeriformes and Strigiformes, can be anticipated. Furthermore, the possibility of broader dispersal of USUV in Europe during the next mosquito seasons must be considered and an increased mortality in Passeriformes and Strigiformes must be expected until protective "flock immunity" is established. Collections of valuable and endangered Passeriformes and Strigiformes, especially young of the year, should therefore be housed indoors or treated against ectoparasites at acceptable intervals between July and September each year.

Bibliography on birds of prey and owls in Slovakia. Part 5. General references and supplements to previous parts
Slovak Raptor Journal, 2012Co-Authors: Marcel Uhrin, Štefan Danko, Hana LatkováAbstract:Abstract The aim of the bibliography is to provide a list of publications on the raptors and owls of Slovakia and of Slovak authors including articles dealing with various organisational issues. The previous parts, which focused on genera from the orders Accipitrifromes, Falconiformes and Strigiformes, are now followed by a fifth part focusing on the raptor and owl species mentioned in various wider associations in the individualarticles. The species, objective and author indexes and the list of periodicals enable better overview

Order Strigiformes, generaTyto, Otus, Bubo, Strix, Surnia, Glaucidium, Athene, Aegolius&AsioThe aim of the bibliography is to provide a list of publications on raptors and owls of Slovakia as well as papers of Slovak authors on these birds. The first three parts focused on genera from orders Accipitrifromes and Falconiformes is followed now by the fourth part focused on genera from Strigiformes order. In total 392 citations are listed - 242 (61.7%) scientific and research articles, 59 (15.1%) popular articles, 21 (5.4%) qualification papers, 45 (11.5%) conference abstracts and 25 (6.4%) reports or other papers. The register of species, objective index and the author register enable better overview.
