ABSTRACT:   Chlamydia trachomatis and Neisseria gonorrhoeae infections are common sexually transmitted infections with a similar pattern of clinical presentation and related sequelae such as urethritis, cervicitis, pelvic inflammatory disease, ectopic pregnancy and infertility. Chlamydial co-infections are also frequently found in patients with gonorrhoea. This study was conducted to optimize a multiplex polymerase chain reaction (M-PCR) assay which could be applied to detect N. gonorrhoeae and C. trachomatis simulta-neously from genitourinary specimens. The procedure of a M-PCR assay, developed by Mahony et al. (1995), was modified by incorporating lambda phage-Neisseria hybrid DNA as an internal control for the detection of amplification inhibitors. Thermal cycling parameters were optimized by varying annealing temperatures and using different concentrations of magnesium chloride, dNTPs and primers. The optimized M-PCR assay had a detection limit of 2.885 x 103 genomecopies for C. trachomatis and 8.995x102 genome copies for N. gonorrhoeae. It was used to detect N. gonorrhoeae and C. trachomatis in 90 endocervical swab specimens from women with vaginal discharge. The specimens were also tested for chlamydial antigen using Clear View test kit (Unipath, UK) and for N. gonorrhoeae by conventional culture. The sensitivity and specificity of the M-PCR assay were found to be superior to those of gonococcal culture and chlamydia antigen testing, making it a potentially useful test for the diagnosis of N. gonorrhoeae and C. trachomatis in lower genital tract infections in symptomatic women.
