Research Abstract
Currently attempts are being made to vaccinate experimental animals with the purified major outer membrane protein (MOMP) of the C. trachomatis mouse pneumonitis biovar. Antibodies to this protein have been shown to occur in a majority of chlamydial infections and furthermore polyclonal and monoclonal antibodies to the MOMP are known to neutralize chlamydial infectivity in vitro. In the animal model mice will be inoculated with the purified MOMP and then they will be challenged with infectious Chlamydiae in the genital tract. The ability of the vaccine to prevent infection and/or to preserve fertility will be determined.
