Molecular characterization of wild-type polioviruses isolated in Greece during the 1996 outbreak in Albania

Abstract

During the present study three type 1 poliovirus strains isolated in Greece during the 1996 poliomyelitis outbreak in Albania were retrospectively investigated and determination of their relationship with other epidemic strains isolated in Albania or elsewhere during previous epidemics was attempted. SimPlot analysis revealed that the three Greek strains are the result of a recombination event in the VP2 coding region.
