We evaluated the clinical performance of the Bio-Rad Dx CT/NG/MG assay for the detection of Chlamydia trachomatis, Mycoplasma genitalium and Neisseria gonorrhoeae in urogenital samples in comparison with the Roche COBAS (R) TaqMan (R) CT assay for C. trachomatis and an in-house TaqMan PCR assay for M. genitalium. Swab specimens were cultured for N. gonorrhoeae. In this prospective study, urogenital samples were obtained from symptomatic and asymptomatic patients attending the sexually transmitted disease clinic of Bordeaux, France, from January to April 2010. A total of 658 clinical specimens (259 male and 180 female urines, 191 vaginal, 21 endocervical and 7 urethral swabs) from 453 patients were analyzed. The prevalence of C. trachomatis and M. genitalium infections was 8.1% (21/260) and 1.9% (5/260) in men and 10.4% (20/193) and 2.1% (4/193) in women, respectively. The Bio-Rad Dx CT/NG/MG clinical sensitivity was 100% for C. trachomatis and NI. genitalium in men and women. In male urine, the clinical specificity was 99.6% for C. trachomatis and 100% for M. genitalium. In women, the specificity was 99.5% for swabs and 100% for urines for detecting C. trachomatis and M. genitalium. All seven N. gonorrhoeae PCR-positive samples were also positive by culture. Patients were co-infected in 5/57 cases (8.8%), with C. trachomatis and M. genitalium in three cases, and C. trachomatis and N. gonorrhoeae in two cases. In conclusion, the Bio-Rad Dx CT/NG/MG assay can be recommended for the simultaneous detection of C. trachomatis, M. genitalium and N. gonorrhoeae in urogenital specimens of symptomatic and asymptomatic individuals.
