Mycoplasma genitalium (MG) is a common cause of non-gonococcal urethritis, but a role in acute or chronic prostatitis has not been described. We describe the case of a 42-year-old man with recurrent urinary tract infections since 2018 who developed chronic prostatitis despite several and prolonged antibiotic courses. Multiparametric prostatic magnetic resonance showed peripheral inflammatory alterations. A 4-glass Meares-Stamey test detected MG in the third voided bladder (VB3) sample. Moxifloxacin 400 mg daily for 28 days resulted in sustained clinical and microbiological cure.

We aimed to better understand factors associated with pelvic inflammatory disease in an outpatient setting.
We analysed the characteristics of pelvic inflammatory disease cases diagnosed in an outpatient setting during 2018. There were 72 cases included in the final analysis.
Of the pelvic inflammatory disease cases analysed, 55% were idiopathic, 22.2% were related to a sexually transmitted infection, and 22.2% had onset of symptoms within 6 weeks of a gynaecological procedure. Of the sexually transmitted infection-positive pelvic inflammatory disease cases, Chlamydia trachomatis was present in 56%, Mycoplasma genitalium was present in 38%, and Neisseria gonorrhoeae was present in 12.5% of cases. Many pelvic inflammatory disease cases had evidence of vaginal dysbiosis or features associated with vaginal flora disruption (recent antibiotic usage and/or vulvovaginal candidiasis).
This case series highlights the burden of Mycoplasma genitalium pelvic inflammatory disease, and clinicians should be aware to include testing for this when diagnosing pelvic inflammatory disease. Our findings also support the hypothesis that host dysbiotic microbiota may contribute to pelvic inflammatory disease pathogenesis, with further research required to explore this proposition.

Data on the prevalence and etiology of infertility in Africa are limited. Secondary infertility is particularly common, defined as the inability of a woman to conceive for at least one year following a full-term pregnancy. We describe a prospective study conducted in Cameroon designed to test the hypothesis of an association between common treatable sexually transmitted infections (STI): Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG), and Trichomonas vaginalis (TV) and secondary infertility in women.
In this case-control study, we enrolled women in Fako Division, Cameroon between November 2017 and December 2018 with secondary infertility (cases) or current pregnancy (controls). We conducted a baseline survey to collect sociodemographic, and sexual and medical history information. Nucleic acid amplification testing using Aptima (Hologic, San Diego, CA, US) was performed on endocervical swabs for CT, NG, MG, and TV. Multivariable logistic regression was used to assess the relationship between active STI and secondary infertility.
A total of 416 women were enrolled: 151 cases and 265 controls. Compared to controls, cases were older (median age 32 vs 27 years) and had more lifetime sexual partners (median 4 vs 3) (p<0.001). Cases were more likely to report dyspareunia, abnormal menses, prior miscarriage, and ectopic pregnancy (all p<0.05). STI positivity was not significantly different among cases and controls (2.7% vs 5.4% for CT, 1.3% vs 2.9% for NG, 6.0% vs 7.0% for MG, respectively), with the exception of TV which was more common in pregnant controls (0.7% vs 5%; p = 0.02).
Study findings did not support an association between active STI and secondary infertility in Cameroon. Given high rates of pre-existing tubal damage, routine STI screening and treatment in younger women may be more impactful than costly STI testing during infertility assessments.

We present a case of persistent Mycoplasma genitalium urethritis with documented macrolide and fluoroquinolone resistance, and we describe the A2062T mutation in the 23S rRNA gene, possibly associated with pristinamycin resistance. After several treatment failures and loss of the A2062T mutation, M. genitalium urethritis was finally cured by a sequential antibiotic treatment including minocycline.

We report a case of Mycoplasma genitalium-positive non-gonococcal urethritis who failed to respond to multiple different courses of antibiotics including azithromycin, minocycline, moxifloxacin and spectinomycin. Extracted M. genitalium DNA from urethral swabs obtained from the patient harbored mutations of 23S rRNA, parC and gyrA. Microbiological cure was eventually achieved by a 14-day course of doxycycline.

Chlamydia trachomatis (CT) and Mycoplasma genitalium (MG) cause the majority of non-gonococcal urethritis (NGU). The role of Ureaplasma urealyticum (UU) in NGU is unclear. Prior case-control studies that examined the association of UU and NGU may have been confounded by mixed infections and less stringent criteria for controls. The objective of this case-control study was to determine the prevalence and aetiology of mixed infections in men and assess if UU monoinfection is associated with NGU.
We identified 155 men with NGU and 103 controls. Behavioural and clinical information was obtained and men were tested for Neisseria gonorrhoeae and CT, MG, UU and Trichomonas vaginalis (TV). Men who were five-pathogen negative were classified as idiopathic urethritis (IU).
Twelve per cent of NGU cases in which a pathogen was identified had mixed infections, mostly UU coinfections with MG or CT; 27% had IU. In monoinfected NGU cases, 34% had CT, 17% had MG, 11% had UU and 2% had TV. In controls, pathogens were rarely identified, except for UU, which was present in 20%. Comparing cases and controls, NGU was associated with CT and MG monoinfections and mixed infections. UU monoinfection was not associated with NGU and was almost twice as prevalent in controls. Men in both the case and control groups who were younger and who reported no prior NGU diagnosis were more likely to have UU (OR 0.97 per year of age, 95% CI 0.94 to 0.998 and OR 6.3, 95% CI 1.4 to 28.5, respectively).
Mixed infections are common in men with NGU and most of these are UU coinfections with other pathogens that are well-established causes of NGU. UU monoinfections are not associated with NGU and are common in younger men and men who have never previously had NGU. Almost half of NGU cases are idiopathic.

Mycoplasma genitalium is an infection of increasing concern due to its potential to cause sequelae in the reproductive tract and the development of antimicrobial resistance. Its role as a cause of proctitis in people with high-risk sexual behaviour has not been properly defined yet but it seems to be less symptomatic than proctitis caused by Chlamydia trachomatis or Neisseria gonorrhoeae. We present a case of a man who has sex with men with proctitis associated with M. genitalium after excluding other infections known to cause STI proctitis.

We report a case of management failure of male urethritis syndrome due to macrolide-resistant Mycoplasma genitalium in South Africa. We detected mutations in 23S rRNA and one of the quinolone resistance-determining regions. This report confirms that drug-resistant M. genitalium infection can undermine the effectiveness of syndromic management in Africa.
