To examine the viability, growth, and immunogenicity of a recombinant poliovirus hybrid expressing a specific neutralization epitope from the major outer membrane protein of Chlamydia trachomatis.
Replaced part of neutralization antigenic site I of poliovirus type 1 Mahoney (PV1-M) with the VAGLEK neutralization epitope from variable domain I of C. trachomatis serovar A MOMP.
Inoculated rabbits with the poliovirus-chlamydia hybrid, equimolar purified native MOMP, or synthetic VAGLEK peptide to evaluate comparative antibody responses.
Assayed rabbit antisera for in vitro neutralization using hamster kidney cells and passive in vivo protection of cynomolgus monkey conjunctival epithelia.
The engineered hybrid virus remained viable, replicated efficiently relative to parent PV1-M, and simultaneously expressed poliovirus and chlamydial antigenic determinants.
Inoculated rabbits generated anti-chlamydia antibody titers 10- to 100-fold higher than those induced by equimolar amounts of purified MOMP or synthetic peptide.
Antisera raised against the hybrid successfully neutralized chlamydial infectivity in vitro in hamster kidney cells and passively prevented conjunctival epithelial infection in cynomolgus monkeys.
