Six viral isolates were obtained from 23,243 female mosquitoes belonging to 16 species and collected along the lower reaches of the Dyje River in South Moravia (Czech Republic) during 2006-2008: five isolates of Orthobunyavirus Ťahyňa (3 isolations from Aedes vexans, 1 from Ae. sticticus, 1 from Culex modestus), and one isolation of Flavivirus West Nile − lineage Rabensburg (from Aedes rossicus). All the isolates were recovered from mosquitoes collected in 2006 (15,882 mosquitoes examined), while no virus was isolated from mosquitoes trapped in 2007 and 2008, when 1,555 and 5,806 mosquitoes were examined, respectively. The population density of local mosquitoes was very low in 2007 and 2008 due to warm and dry summer. The virus isolation procedure was based on intracerebral inoculation of newborn mice. In parallel, more than one-third of the samples were also examined by inoculating Vero cell cultures. However, the latter method detected only 3 of the 6 virus isolates.
