Identification of organisms detected in men with or without non-gonococcal urethritis
| Agent | Cases (n = 119) | Controls (n = 117) | OR (95% CI) | aOR (95% CI)* |
| Prior study9 | ||||
| Chlamydia trachomatis | 36 (30.3) | 4 (3.4) | 12.2 (4.7 to 35.8) | NA |
| Mycoplasma genitalium | 27 (22.7) | 5 (4.3) | 6.4 (2.4 to 17.4) | 6.5 (2.1 to 19.9) |
| Ureaplasma spp by culture† | 51 (42.9) | 59 (50.4) | 0.9 (0.4 to 1.2) | NA |
| Current study—species-specific PCR | ||||
| U urealyticum | 31 (26.1) | 19 (16.2) | 1.8 (0.96 to 3.4) | 2.3 (1.04 to 4.9) |
| U parvum | 17 (14.3) | 34 (29.1) | 0.4 (0.2 to 0.8) | 0.4 (0.2 to 0.8) |
Unless otherwise indicated, data are presented as no./total (%) of patients with characteristic.
↵* Estimates for U urealyticum adjusted for age, racial identity, history of previous urethritis, and detection of C trachomatis and M genitalium, all characteristics that differed among cases and controls (p<0.1) in our original report. Estimates for U parvum adjusted for age, racial identity and detection of C trachomatis and M genitalium.
↵† Ureaplasma culture results, which do not differentiate the two ureaplasma species, were obtained from a previous study9 The detection of the newly recognised ureaplasma species, U urealyticum and U parvum, by PCR was performed in the current study.
