Serologic Investigation on Tick-Borne Encephalitis Virus, Kemerovo Virus and Tribec Virus Infections in Wild Birds.

ABSTRACT: The present study reports on serosurvey on the tick-borne encephalitis virus European subtype (TBEV; genus Flavivirus), and the tick-borne Kemerovo (KEMV) and Tribeč (TRBV) orbivirus (genus Orbivirus) infections in tick-infested and non-infested birds. No virus RNA was detected in the blood clots. Birds were infested mostly by Ixodes ricinus, but Haemaphysalis concinna and I. frontalis were observed too. TBEV, KEMV and TRBV neutralising antibodies (NAb) were detected in the screening microtitration neutralisation test (μVNT). Seropositive samples were further examined in simultaneous μVNT to distinguish TBEV infection from WNV and USUV. KEMV and TRBV infections were also further examined by μVNT against each other. The demonstrated results point to increased TBEV and TRBV seroprevalence in
