Abstract

Background: Mycoplasma genitalium (MG) has increasingly been recognised as a pathogen of importance given its association with persistent urethritis, antibiotic resistance and potential complications (e.g., pelvic inflammatory disease). Here, we assess MG positivity and co-infection with Chlamydia trachomatis (CT) and/or Neisseria gonorrhoeae (NG) during a trial assessing the clinical performance of the cobas® CT/NG/MG test (assay not cleared by US FDA. Submission currently under review and subject to change per health authority feedback), a polymerase chain reaction (PCR)-based assay for point-of-care testing. Methods: This non-interventional study assessed MG positivity in prospectively collected (by clinicians/participants) specimens (urine/vaginal swabs in cobas® PCR Media) from symptomatic/asymptomatic patients 14 years of age from 13 sites across the US. Participants were designated as being infected ( +) or not infected (-) with CT, NG and MG based on combined results from three FDA-cleared assays and one laboratory-developed test. Co-infection rates were determined for samples with valid results for CT, NG and MG. Results: Median (range) age of the study population (N = 4800) was 35.0 (15.0-81.0) years, 40.4% were symptomatic and 51.9% were assigned female at birth. MG positivity among all/symptomatic/asymptomatic participants was: 9.lo/o/12.3%/7.3% (male urine), 9.2%/ 12.1%/6.9% (clinician-collected vaginal swab), 11.2%/10.5%/1 l.8% (self-collected vaginal swab) and 10.2%/11.3%/9.2% (female urine). Co-infection results were as follows: CT+ /NG+ /MG+ (n = 2), CT+ /NG+ (n = 15), er+ /MG+ (n = 19) and NG+ /MG+ (n = 11) in male urine samples; CT+ /NG+ /MG+ (n = 5), CT+ /NG+ (n = 4), CT+ /MG+ (n = 35) and NG+ /MG+ (n = 7) in vaginal samples; er+ /NG+ /MG+ (n = 3), CT+ /NG+ (n = 3), CT+ /MG+ (n = 27) and NG+ /MG+ (n = 6) in female urine samples. Conclusions: In this US-based population, rates of MG positivity were high and MG co-infection with CT and/or NG was common. The ability to detect MG may facilitate improved antimicrobial stewardship by supporting early treatment optimisation, in addition to reducing onward MG transmission. Co-infection frequency strongly supports multiplex testing.
