Epidemiology and prevalence of mutations associated with resistance to macrolides and fluoroquinolones in Mycoplasma genitalium in a tertiary hospital from Madrid, Spain.
Objective: Mycoplasma genitalium causes persistent sexually transmitted infections. The aims of this study were to estimate the prevalence of resistances to macrolides and fluoroquinolones in M. genitalium and the sexually transmitted coinfections in patients at Hospital Universitario La Paz (Madrid, Spain).
Methods: Patients attended between January and October 2021 were studied. Screening for sexually transmitted pathogens and detection of 23S rRNA and parC genes mutations were performed by real-time PCR (Allplex,SeegeneTM).
Results: A total of 1,518 females and 1,136 males were studied. The prevalence of M. genitalium was 2.1%. The macrolides resistance rate was 51.8%. The mutations found were A2059G, A2058T and A2058G. The rate of resistance to fluoroquinolones was 17.8% being the G248T mutation (S83I) the most frequent. Seven males had some sexual transmitted coinfection.
Conclusions: Although the percentage of M. genitalium infections is low, the high rate of resistance to macrolides makes it necessary to revise the protocols for diagnosis and empirical treatment of sexually transmitted infections. The use of fluoroquinolones is appropriate after screening of macrolide resistance profile.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
