Abstract
The major outer membrane protein (MOMP) of Chlamydia trachomatis carries serovar-, subspecies-, and genus immunodomains, antibodies to which may be protective. We have compared the inferred amino acid sequences for MOMP from different serovars of C. trachomatis and from Chlamydia psittaci to identify the likely locations of these sero-taxonomic epitopes. Overlapping peptides corresponding to each of these regions were synthesized on a solid phase and probed with monoclonal antibodies (MAbs) of appropriate specificities. We describe the primary structures of the binding sites of MAb to each of these four epitopes on C. trachomatis serovar L1 MOMP.
