Analy zing Genomes of Tick-Bone Encephalitis Virus Strains with Various Human Virulence

Abstract

The FE-subtype tick-bone encephalitis strains are capable
of causing disease of various severities. To identify ties between
the disease severity and the virus genome structure, the authors
have detected full-genome nucleotide sequences of strains derived
from both dead persons (high virulent strains) and persons with no
evident symptoms of the disease (unapparent strains). These two
groups of the virus strains were on the phylogenetic tree in different
clusters. Besides, these groups varied by 19 available group-specific
mutant sites in virus proteins. Four mutations caused considerable
changes in the properties of amino acid residues and, were likely to
be key to identify the pathogenicity of the strain.
