Tick borne encephalitis virus (TBEV) (Flaviviridae, Flavivirus) is the causative agent of tick-borne encephalitis (TBE), a potentially fatal neurological infection. The disease is endemic in a large region in Eurasia, where is transmitted mainly by hard ticks: Ixodes ricinus and I. persulcatus. It is known that also Dermacentor reticulatus is involved in a circulation of TBEV, but the knowledge of its importance in the TBE epidemiology is still insufficient. The Bialowieza Primeval Forest is located in eastern Poland and it is a well-known endemic focus of tick-borne encephalitis. The aim of this study was to identify the prevalence of tick-borne encephalitis virus (TBEV) in Dermacentor reticulatus ticks collected from European bison (Bison bonasus bonasus), an important host of hard ticks in the Bialowieza Primeval Forest. In the years 2008-2009, a total of 114 adult D. reticulatus ticks were collected from 7 European bison and examined individually for the presence of TBEV RNA using nested RT-PCR assay. Positive results were noted in 18.42% of ticks. This is the first record of TBEV infection in ticks collected from European bison.
