[Genetic characterization of the Batken virus (BKNV) (Orthomyxoviridae, Thogotovirus) isolated from the Ixodidae ticks Hyalomma marginatum Koch, 1844 and the mosquitoes Aedes caspius Pallas, 1771, as well as the Culex hortensis Ficalbi, 1889 in the Central Asia].

The prototype strain LEIV-K306 of the Batken virus (BKNV) was isolated from the Ixodidae ticks Hyalomma marginatum Koch, 1844 collected from sheep near town Batken (Kirgizstan) in the April 1970. Later, the BKNV was isolated in Kirgizstan from the mixed pool of the Aedes caspius Pallas, 1771 and Culex hortensis Ficalbi, 1889 mosquitoes. From the very beginning, the BKNV was discussed to be very close to the Dhori virus (DHOV) (Orthomyxoviridae, Thogotovirus) isolated from the Ixodidae ticks Hyalomma dromedarii Koch, 1844 in India.

[Arborviruses of the California encephalitis serogroup 1N Russia and their contribution to infectious pathology].

This review focuses on arborviral infections associated with California serocomplex (Bunyaviridae, Orthobunyavirus). Results of relevant eco-epidemiological and clinical studies in Russia are presented suggesting the ubiquitious nature of diseases caused by viruses of the California encephalitis serocomplex (Inko, Tahyna, Snowshoe Hare). The etiologic structure of these diseases in taiga and mixed woods of the European part and Western Siberia is dominated by the Inco virus and in southern regions by Tahina.

[Phylogenetic analysis of the nucleotide sequences of Chatanga virus strains, the new representative of California encephalitis serocomplex, isolated in different regions of the Russian Federation].

The complete nucleotide sequences of the S segment and the fragments of M and L segments (on 900 and 410 nucleotides, respectively) were determined in 14 California encephalitis serocomplex (CES) strains isolated from different regions of the Russian Federation. Phylogenetic analysis by the sequences of genomic S, M, and L segments indicated that all Russian strains were an individual independent CES virus. The new virus is named Chatanga for the place of isolation of one of the strains.

[Analysis of the genome of two Getah virus strains (LEIV 16275 Mar and LEIV 17741 MPR) isolated from mosquitoes in the North-Eastern Asia].

The complete nucleotide consequences of two Getah virus strains isolated in Russia (LEIV 16275 Mar) and Mongolia (LEIV 17741 MPR) were first determined and analyzed. The nucleotide sequences of the gene of surface glycoprotein E2 and complete genome were used to establish the phylogenetic relations of the strains with other representatives of the Semliki forest serocomplex. The study and reference strains of Getah virus were shown to form its own cluster that was far away from other representatives of the complex and the sequence of the E2 gene significantly reflected the identification of phylogenetical groups within the Sempliki forest serocomplex.

[Isolation of influenza virus A (Orthomyxoviridae, Influenza A virus), Dhori virus (Orthomyxoviridae, Thogotovirus), and Newcastle's disease virus (Paromyxoviridae, Avulavirus) on the Malyi Zhemchuzhnyi Island in the north-western area of the Caspian Sea].

The paper presents the results of the 2003 and 2006 environmental virological monitoring surveys on the Malyi Zhemchuzhnyi Island where a large breeding colony of sea gull (Laridae) is located. In the past several years, expansion of cormorants (Phalacrocorax carbo) has enhanced the intensity of populational interactions. The investigators isolated 13 strains of influenza A virus (Orthomyxoviridae, Influenza A virus) subtype H13N1 (from sea gulls (n = 4), cormorants (n = 9) 1 strain of Dhori virus (Orthomyxoviridae, Thogotovirus) from a cormorantwith clinical symptoms of the disease, 3 strains of Newcastle disease virus (Paramyxoviridae, Avulavirus) from cormorants.
