Analysis of Ebola virus Zaire 2014 isolates

Abstract

Analysis of 5 Ebola virus Zaire 2014 isolates passaged in cell cultures or in mice, demonstrated presence of unique mutations in the genome RNA in some cases. All identified nucleotide substitutions are singular, stochastically located, synonymous or fall within non-coding regions. Variability level of nucleotide sequences is equal to 0.005-0.01 %, suggesting extremely high genetic stability of Ebola virus Zaire, the causative agent of the outbreak. Confirmed is suppression of non-synonymous mutations accumulation in ebolavirus variants in the course of time. Detected are alterations in glycosilation sites and mucin-like domain of ebolavirus glycoprotein.
