Abstract
Searching for specific antibodies in bird serum could reveal arbovirus activity in certain localities. To date, no systematic surveillance for arbovirus infection in autochthonous population of wild birds has been conducted in Slovakia. Present study includes birds captured on spring migration and birds of the autochthonous nesting population of the Drienovska wetland (Slovakia). Serum samples were tested for West Nile virus (WNV), Usutu virus (USUV), Tick-borne encephalitis virus (TBEV) and Tribec virus (TRBV) neutralizing antibodies (NAb). Blood samples were collected during 2017 spring migration (March – April) and from local breeders and hatched juveniles (May – July) caught by Constant Effort site ringing method. Specific NAb were detected by micro-titration virus neutralization test. WNV NAb were detected in 11.7% (18/153) of sampled birds. Ten WNV seropositive were migrants (Eurasian Robins, Eurasian Blackcap and a Great Tit), 5 were nesting adults (Song Thrush, White Throat, Eurasian Jay, Hawfinch and Eurasian Blackbird) and 3 were juveniles (Song Thrush, Common Starling and a Great Tit). There was not confirmed USUV infection in any of the examined birds. TBEV NAb were detected during breeding season in the adult Eurasian Blackcap, which means 1.1% (1/93) seropositivity. TRBV NAb was detected in 7.4% (5/68) of adult birds (Eurasian Blackbirds and a Common Starling) and in one juvenile Great Tit, which had also WNV Nab as well. These results suggest active transmission of at least two arboviruses in the autochthonous avifauna in Slovakia.

Abstract In central Europe, at least three flaviviruses circulate among vectors and vertebrate hosts. West Nile virus (WNV) and Usutu virus (USUV) are mosquito-borne viruses maintained in the nature by enzootic cycle between mosquitoes and birds. Tick-borne encephalitis virus (TBEV) is a flavivirus causing annual human cases in Slovakia. The aim of this study is the prevalence assessment of flavivirus infections in horses (n = 145) and birds (n = 109) by enzyme-linked immunosorbent assay (ELISA)...

West Nile virus (WNV) is a mosquito-borne neurotropic pathogen that presents a major public health concern. Information on WNV prevalence and circulation in Slovakia is insufficient. Oral and cloacal swabs and bird brain samples were tested for flavivirus RNA by RT-PCR using newly designed generic primers. The species designation was confirmed by sequencing. WNV was detected in swab and brain samples, whereas one brain sample was positive for tick-borne encephalitis virus (TBEV). The WNV sequenc...

Ixodid ticks (Acari: Ixodidae) are known as primary vectors of many pathogens causing diseases in humans and animals. Ixodes ricinus is a common ectoparasite in Europe and birds are often hosts of subadult stages of the tick. From 2012 to 2013, 347 birds belonging to 43 species were caught and examined for ticks in three sites of Slovakia. Ticks and blood samples from birds were analysed individually for the presence of Rickettsia spp. and Coxiella burnetii by PCR-based methods. Only I. ricinus ...

Antibody duration, following a humoral immune response to West Nile virus (WNV) infection, is poorly understood in free-ranging avian hosts. Quantifying antibody decay rate is important for interpreting serologic results and for understanding the potential for birds to serorevert and become susceptible again. We sampled free-ranging birds in Chicago, Illinois, US, from 2005 to 2011 and Atlanta, Georgia, US, from 2010 to 2012 to examine the dynamics of antibody decay following natural WNV infecti...

Usutu virus (USUV) is an African mosquito-borne flavivirus belonging to the Japanese encephalitis virus serocomplex. USUV is closely related to Murray Valley encephalitis virus, Japanese encephalitis virus, and West Nile virus. USUV was discovered in South Africa in 1959. In Europe, the first true demonstration of circulation of USUV was reported in Austria in 2001 with a significant die-off of Eurasian blackbirds. In the subsequent years, USUV expanded to neighboring countries, including Italy,...

To the Editor: Usutu virus (USUV) is an arthropod-borne flavivirus that belongs to the Japanese encephalitis serocomplex (1). USUV circulates between ornithophilic mosquito vectors (mainly Culex spp. mosquitoes) and avian amplification hosts (2). Migratory birds play a key role in the introduction of USUV into new areas (3). USUV has recently been introduced from Africa into Europe, causing epizootics among wild birds and Usutu fever in humans (4–6). The detection and isolation of USUV from diff...

Monitoring West Nile virus (WNV) and Usutu virus (USUV) activity now has the highest priority among mosquito-borne pathogenic viruses circulating in the European Union. This study documents a first time detection and the co-circulation of WNV lineage-2 (with the minimal prevalence of 0.46%) and USUV clade Europe 2 (with the minimal prevalence of 0.25%) in mosquitoes from the same habitat of south-western Slovakia and underlines necessity to perform rigorous surveillance in birds, mosquitoes, hor...
