Flavivirus species recognition based on the polyprotein coding sequences

Method recognizing the flavivirus species, including a subtype recognition, that based on the genome sequence analysis, is proposed. This method takes into consideration frequency characteristics of amino acid codons in the coding sequences of full-length polyprotein of flavivirus genomes. High reliability of the method is proved in recognizing flavivirus genomes from 15 groups of different species and sub-types, that are sufficiently represented in the GenBank database. Ten various species of the flaviviruses, four sub-types of Dengue virus and Kunjin virus, that is suggested to be a sub-type of West Nile virus, are considered in the work.
