Introduction: The objective of this study was to analyse the susceptibility of Mycoplasma genitalium to macrolides and fluoroquinolones using molecular techniques. Methods: Susceptibility to macrolides was tested (Gipuzkoa, 2014-2017) by a rapid probe-based real-time polymerase chain reaction assay (23S rRNA gene) and to fluoroquinolones by sequencing the parC and gyrA genes. Results: Mutations associated with macrolide resistance were detected in 43/263 (16.3%) cases and potential fluoroquinolone resistance in 21/267 (7.9%). Macrolide resistance was more frequent in patients previously treated with azithromycin (76.5% vs 7.4%, P <.001) as well as in those treated with a single 1 g dose (31.3%) vs the extended regimen (7%, P<.001). There were 5/245 (2%) cases with mutations probably associated with resistance to both antibiotics. Conclusions: The technique used for testing Mycoplasma genitalium susceptibility to azithromycin allowed the rapid implementation of resistance-guided antibiotic therapy. Moxifloxacin could be a good option in cases of macrolide resistance. (C) 2018 Elsevier Espana, S.L.U. and Sociedad Espanola de Enfermedades Infecciosas y Microbiologia Clinica. All rights reserved.
