      In this study, the immunity level of the southern Greek population in the 1-10-year, 11-20-year, 21-30-year and 31-40-year age groups with regard to Sabin vaccine strains and a collection of 11 recombinant and three ...
    • Retrospective molecular and phenotypic analysis of poliovirus vaccine strains isolated in Greece 

      Pliaka, V.; Filliponi, M. E.; Kyriakopoulou, Z.; Ruether, I. G. A.; Tsakogiannis, D.; Gartzonika, C.; Levidiotou-Stefanou, S.; Markoulatos, P. (2011)
      The live oral poliovirus vaccine (OPV) strains are genetically unstable, causing, in rare cases, vaccine-associated paralytic poliomyelitis. Reversions of the known attenuating mutations in OPV strains and intertypic ...
    • Use of mutational pattern in 5 '-NCR and VP1 regions of polioviruses for molecular diagnosis 

      Pliaka, V.; Dedepsidis, E.; Kyriakopoulou, Z.; Papadopoulou, I.; Levidiotou, S.; Markoulatos, P. (2007)
      Polioviruses are members of the enterovirus genus, belonging to the Picornaviridae family. They are the causative agents of poliomyelitis, a paralytic and sometimes fatal disease in humans. The number of poliomyelitis cases ...
