[Examination of mosquitoes collected in southern Moravia in 2006-2008 tested for arboviruses].

The main goals of the study were to carry out virus isolation attempts on Vero cell cultures from mosquitoes collected in southern Moravia (Breclav district, Czech Republic) and to identify the isolates using a microtiter virus neutralization test. A total of 9.742 female mosquitoes belonging to 13 species were examined, and three viral strains were isolated, all from the mosquitoes collected in 2006: two of these isolates were identified as Tahyna Orthobunyavirus (both obtained from Aedes vexans mosquitoes) and one was West Nile flavivirus (obtained from Aedes rossicus mosquitoes).

Mosquito (Diptera: Culicidae) surveillance for arboviruses in an area endemic for West Nile (Lineage Rabensburg) and Tahyna viruses in Central Europe.

Six viral isolates were obtained from 23,243 female mosquitoes (examined in 513 pools) belonging to 16 species and collected along the lower reaches of the Dyje River in South Moravia (Czech Republic, central Europe) during 2006-2008: five isolates of Orthobunyavirus Tahyna (TAHV, California group, family Bunyaviridae: three isolations from Aedes vexans (Meigen), one from Ae. sticticus (Meigen), one from Culex modestus Ficalbi); and one isolation of Flavivirus West Nile (WNV, Japanese encephalitis group, family Flaviviridae)-strain Rabensburg (proposed lineage 3 of WNV) from Ae. rossicus (Dolbeshkin et al).
