ABSTRACT
Introduction
Mycoplasma genitalium (MG) causes frequently asymptomatic STIs. MG prevalence figures are lacking and management is complicated by the lack of etiological diagnostics and high antimicrobial resistance in many countries. Appropriately validated, quality-assured, and FDA-approved MG diagnostic assays have been lacking.
Areas covered
The clinical and analytical performance characteristics of the Aptima® MG assay, the first FDA-approved MG nucleic acid amplification test (NAAT), are summarized. Key priorities in the management and control of MG infections are also discussed.
Expert opinion
Highly sensitive, specific, and quality-assured MG NAATs, e.g. the Aptima MG assay on the automated and flexible Panther® platform, are imperative to improve the management and control of MG infections internationally. This testing, combined with macrolide-resistance testing (not yet available on the Panther platform), offers a rapid, high-throughput, and appropriate diagnosis of MG. Macrolide resistance-guided sequential treatment needs to be implemented for MG infections. Dual antimicrobial therapy, novel antimicrobials and, ideally, a vaccine may become essential.
Article highlights
M.genitalium infections are prevalent and exceedingly difficult to manage due to limited etiological diagnostics and high prevalence of AMR.
Validated, appropriate and quality-assured NAATs for detection of M.genitalium, combined with macrolide-resistance testing, are imperative for adequate management.
The FDA-approved and CE/IVD-marked Aptima M.genitalium assay (Hologic) on the automated, flexible and high-throughput Panther platform (Hologic), has an excellent sensitivity and specificity.
The Aptima M.genitalium assay offers a simple, rapid, and appropriate M. genitaliumdiagnostics, which can easily be combined with simultaneous detection of C. trachomatis, N. gonorrhoeaeandT. vaginalis.
Macrolide resistance-guided sequential treatment, initiated with doxycycline presumptive therapy, should be implemented for M. genitaliuminfections.
Dual antimicrobial therapy, novel antimicrobials and, ideally, a vaccine may become essential.
