Serological profiling with Chlamycheck, a commercial multiplex recombinant antigen Western blot assay of chlamydial infections.
A new chlamydial test system, the Chlamycheck assay, which uses 4 purified recombinant antigens of Chlamydia trachomatis and Chlamydophila pneumoniae and one antigen of Chlamydophila psittaci, has been developed and commercialized. We investigated the reactivities of the recombinant antigens with sera from a group of 30 patients with acute Chlamydia trachomatis infection, 88 patients consulting for sexually transmitted infections, and 46 patients with serological evidence of Chlamydophila pneumoniae infection. The results obtained from human and infected mouse sera suggest that Chlamycheck serology against multiple proteins may provide additional useful information that is not available by conventional whole elementary body microimmunofluorescence or single-antigen enzyme-linked immunosorbent assay serology. Specific serological profiles were associated with acute versus past Chlamydia trachomatis infection or with Chlamydia trachomatis primo-infection versus infection in a Chlamydophila pneumoniae history context.
