Area of Science:

  • Virology
  • Molecular Biology
  • Immunology

Background:

  • Poliovirus is a well-understood virus and the cause of paralytic poliomyelitis.
  • Infectious cDNA clones of the Sabin 1 poliovirus vaccine strain are available.
  • Recombinant-DNA technology allows for genetic manipulation of viruses.

Purpose of the Study:

  • To create novel hybrid polioviruses with altered antigenic properties.
  • To explore the potential of these engineered viruses as 'epitope-presentation systems'.

Main Methods:

  • Utilized recombinant-DNA technology.
  • Employed infectious cDNA clones of the Sabin 1 poliovirus vaccine strain.
  • Constructed hybrid viruses (chimeras) by combining genetic material.
