Heterotypic Antibody Responses by Rabbits Inoculated with Poliovirus

[摘要] Rabbits were found to acquire neutralizing capacity for homotypic and heterotypic poliovirus and for ECHO 12 virus following inoculation with a single poliovirus type. The neutralizing capacity for heterotypic and heterologous viruses was shown to have properties of antibody, in that it was produced by antigenic stimulus, was demonstrated in heat-inactivated sera and was not dependent upon the cellular component of the antigen. Rabbits previously immunized with type 2 poliovirus were found to have an enhanced (anamnestic) response to the poliovirus type 1 and 3 components of trivalent vaccine when compared with the control, unsensitized rabbits. Such an anamnestic response was further evidence for the antigenic relationship of of the three poliovirus types.
