    A polymerase chain reaction (PCR) was developed to detect Chlamydia trachomatis in genital tract specimens. Two sets of primers for the PCR were used; one set amplifies a region of the plasmid present in all C trachomatis strains and the other amplifies a conserved region of the genome coding for the major outer membrane protein. The sensitivity of these PCRs were compared with each other, and with the sensitivities of antigen ELISA, Clearview and culture. Southern blotting and probing was used to increase sensitivity of detection.
