Results of tick testing for detection of viruses of Karshi, Tamdy, Issyk-Kul fever, Syr Darya valley fever

In Kazakhstan natural foci of Crimea-Congo hemorrhagic fever is located on the territory of Turkestan, Kyzylorda and Zhambyl regions. Whereas preventive measures are taken, this disease is diagnosed annually among people, but there is a group of viruses such as Karshi, Tamdy, the Issyk-Kul fever virus and Syr Darya valley fever which are less known. In this regard the goal was set to identify the prevalence of viruses of Karshi, Tamdy, Issyk-Kul fever and fever of the Syr Darya valley in hemorrhagic fever endemic in the Crimea-Congo hemorrhagic fever to determine the main hosts and vectors of infection. Ticks captured in areas natural foci of the Crimean-Congo hemorrhagic fever virus. The species composition of captured ticks was represented by 9 species: Hyalomma scupense, Hyalomma asiaticum, Hyalomma turanicum, Hyalomma anatolicum, Haemaphysalis sucata, Haemaphysalis punctata, Dermacentor niveus, Rhipicephalus pumilio, Rhipicephalus schulzei. Preliminary work was carried out on the selection and design of oligonucleotide primers for the identification of viruses by molecular genetic analysis. As a result of the studies, positive samples were found for viruses of Tamdy and Syr Darya valley fever in ticks H. asiaticum, H. scupense from the Turkestan region. The Crimean-Congo hemorrhagic fever virus was detected in H. asiaticum and H. scupense ticks from Zhambyl and Turkestan regions.
