First detection of tacheng tick virus 2 in hard ticks from southeastern kazakhstan

Abstract

We aim to detect the presence of Tacheng tick virus 2 (TcTV-2) in ticks of southeastern Kazakhstan. A total of 205 ticks were collected and separated into four species, namely Hyalomma scupense, Dermacentor marginatus, Hyalomma asiaticum and Hyalomma anatolicum. The partial S segment of TcTV-2 was detected in individual RNA of separated ticks by reverse transcriptase polymerase chain reaction. 11.22% (23/205) of ticks were positive to the viral S segment. This is first report of presence of the TcTV-2 in Hy. scupense and Hy. anatolicum from Kazakhstan. This finding extends tick species and the geographic distribution of TcTV-2.
