Antibiotic resistance in Mycoplasma genitalium (MG) is rising globally, especially to macrolides. In response to this challenge, assays reporting both the detection of MG and macrolide resistance-mediating mutations (MRMM) allow therapy to be tailored to the individual. The study evaluated the performance of the ResistancePlus® MG FleXible assay for the detection of MG and MRMM. Overall, the test performed well for the detection of MG compared to the Allplex STI Essential assay, used as a reference, with a kappa value of 0.926 (95% CI, 0.863-0.990). The kit also performed well for the detection of MRMM when compared with Sanger sequencing of the 23S rRNA gene, with a kappa value of 0.901 (95% CI, 0.807-0.996). The rate of MRMM in MG among the study population was 41.8%. In conclusion, the ResistancePlus® MG FleXible is a rapid, simple, and accurate cartridge-based assay for simultaneous detection of MG and MRMM in clinical settings.

We evaluated the ResistancePlus® MG assay in providing macrolide resistance-guided treatment (RGT) for infection at a UK sexual health centre. -positive samples from men with urethritis and women with pelvic inflammatory disease (PID) were tested for macrolide resistance-mediating mutations (MRMMs). MRMM-positive infections were given moxifloxacin 400 mg; otherwise 2 g azithromycin (1 g single dose and then 500 mg OD) was given.

Background: Bacterial vaginosis (BV) is a common condition in reproductive-age women and is known to be positively associated with risk of acquisition of sexually transmitted infections (STI) such as chlamydia and gonorrhea. Mycoplasma genitalium is an emerging STI that has been linked to increased risk of pelvic inflammatory disease, adverse pregnancy outcomes and infertility. In the present study we sought to examine whether women diagnosed with symptomatic BV were at increased risk of having concurrent infection with Mycoplasma genitalium.

Antibiotic resistance in is rising globally, and resistance-guided diagnostics can facilitate targeted and timely treatment. The ResistancePlus MG FleXible (RPMG Flex) assay for the detection of and macrolide resistance-mediating mutations (MRMM) was evaluated for analytical sensitivity, specificity, reproducibility, and inhibition in the presence of interfering substances by simulating -negative pooled urine and swab matrices with cultures. Furthermore, the clinical sensitivity of the assay was evaluated and compared with a reference real-time PCR assay.

Background: The increasing prevalence of macrolide resistant Mycoplasma genitalium is a major concern worldwide. In Cuba, several cases of clinical treatment failure with 1 g single dose and extended azithromycin regimen have been detected and the aim of the present investigation was to retrospectively determine the prevalence of macrolide-resistance mediating mutations (MRMM) in M. genitalium-positive samples conserved at the Cuban National Reference Laboratory of Mycoplasma Research between 2009 and 2016.
