title: [Genetic characteristics of the S-segment of RNA from two strains of the Crimean-Congo hemorrhagic fever virus isolated in the south of Russia and in Uzbekistan].
abstract: Complete S-segment nucleotide sequences of genomic RNA were determined for two Crimea-Congo hemorrhagic fever (CCHF) virus strains, i.e. LEIV 10145 Uz isolated from ticks in Uzbekistan, 1985, and LEIV 29223 Stv isolated from a patient in Stavropol region, 2000. It was established that the S-segment length is 1672 and 1674 nucleotides. Therefore, the initiating codon (for methionine) is located at positions 56-58; the length of translation frames for the nucleocapsid protein is 482 amino acid residues. Distinctions in the length of S-segment, as compared to other strains, are related only with the 5' and 3' non-coding regions. A comparison of the nucleotide and amino-acid sequences of S-segments of genome of the mentioned strains with the early published data showed that the CCHF virus strain isolated in Uzbekistan is mostly close to strains isolated in China, and that the strain isolated in Stavropol region forms, jointly with Drozdov strain isolated in the Astrakhan region, a separate branch in the phylogenetic tree.
