Enteroviruses, the main cause of aseptic meningitis, consist of 100 serotypes, and many of them have been associated with large outbreaks. In the present study, a comparison of RFLP analysis of the 5' untranslated region ...

Correlation between recombination junctions and RNA secondary structure elements in poliovirus Sabin strains

Dedepsidis, E.; Kyriakopoulou, Z.; Pliaka, V.; Markoulatos, P. (2010)

In order to test the hypothesis that RNA structural elements promote the distribution of certain types of recombination junctions in each one of the 2C and 3D poliovirus genomic regions (Sabin 3/Sabin 2 or Sabin 1 in 2C ...
