[Molecular genetic echovirus 9 variants identified in patients with aseptic meningitis in Russia in 2007-2009]
Abstract:
In 2009 echovirus 9 caused a higher seasonal incidence of enterovirus infection (EVI) and its several outbreaks in a number of regions of Russia. Analysis of the partial VP1 coding region differentiated 4 phylogenetic lineages of echoviruses 9 variants identified in patients with aseptic meningitis and EVI in 2007-2009. One variant of echovirus 9 was most commonly encountered in 2009. Echoviruses 9 identified in different areas, which had a high (98.2-100%) homology of nucleotide sequences of the partial VP1 coding region, varied in the amino acid sequences within the B-C loop.
