Abstract
Background: The Turkestan region of Kazakhstan is the natural focus of the Congo-Crimean hemorrhagic fever (CCHF). Every year, some of the patients treated in hospitals are not included in official statistics and remain in the group of possible cases of CCHF. Objectives: This study aimed to verify the genotypes of the CCHF virus (CCHFV) in the Turkestan region and Shymkent City. Methods: Twelve blood samples from patients with CCHF were studied, the diagnosis of which was verified on the basis of positive specific immunoglobulins IgM to the virus. To isolate viral RNA, we used a special MAGNO-sorb kit. To detect RNA, CCHFV was used with a set of Amplisens CCHFV-FL by real-time polymerase chain reaction (PCR) using a Rotor-Gene Q device. For the reverse transcription reaction, we used a set of Reverta-L. Results: The study of the genome sequence of CСHFV from GenBank demonstrated that isolates from the Turkestan region belonged to genetic groups Asia-1 and Asia-2. Conclusions: For the first time in Kazakhstan’s history, a phylogenetic analysis of RNA sequences of viruses from patients with CCHF was performed in the Turkestan region, as a result of which genetic groups Asia-1, reassortant Asia-1, and Asia-2 were established

Abstract
Aim: The objective was to investigate the genotypic relationship of S and M segments in Crimean-Congo hemorrhagic fever virus (CCHFV) by phylogenetic analysis in 25 patients from seven endemic cities in Turkey. Materials & methods: A total of 25 samples from patients with CCHF were included between 2012 and 2015. Phylogenetic tree analyses were inferred using MEGA version-6.0 and distances were calculated by Kimura’s 2-parameter. Results: Phylogenetic analysis showed that all isolated viruses (n = 25) were in the predicted clades such as clade V- Europe-1 regarding both S and M segments of the CCHFV. Conclusion: Further epidemiological, molecular and phylogenic studies should be performed in both reservoir animals/vectors and humans to determine the incidence of tick-borne infectious disease and to help to develop vaccines for prevention of the disease.
