Chimeric polioviruses have been prepared in which part of the antigenic site 1-encoding sequence of the Sabin strain of type 1 poliovirus has been replaced by sequences based on those found in the homologous region of the Sabin type 3 strain. The chimeras were analysed for their reaction with polyclonal and monoclonal antibodies raised against type 1 and type 3 viruses, and with polyclonal antipeptide sera, as well as for their immunogenicity in animals. The effectiveness with which the type 3 site was presented antigenically varied in ways which were partially predictable, based on the behaviour of type 3 mutants with monoclonal antibodies. However, other factors were implicated which may include conformational effects and other components of the site in addition to those altered in the chimeras. The ability of the chimeras to induce antibodies reacting with type 3 polioviruses paralleled their antigenic reactivity, and evidence is presented for the induction of strain-specific antibodies.

UI MeSH Term Description Entries
D009154 Mutation Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations. Mutations
D011055 Poliovirus Vaccine, Oral A live vaccine containing attenuated poliovirus, types I, II, and III, grown in monkey kidney cell tissue culture, used for routine immunization of children against polio. This vaccine induces long-lasting intestinal and humoral immunity. Killed vaccine induces only humoral immunity. Oral poliovirus vaccine should not be administered to immunocompromised individuals or their household contacts.
