The aim of this retrospective and comparative study was to conduct the clinical evaluation of three commercially available kits for macrolide resistance detection. A total of 111 M. genitalium positive samples analyzed in the Clinical Microbiology Laboratory of the Miguel Servet University Hospital, Zaragoza (Spain) were used. After M. genitalium molecular confirmation, the three assays under study were evaluated and discrepant results were resolved via sequencing. The clinical sensitivity for resistance detection was 83% (95% confidence interval, 69% to 93%) for the ResistancePlus\u00ae MG panel kit (SpeeDx Pty Ltd., Sydney, Australia), 95% (84% to 99%) for AllplexTM MG &amp; AziR Assay (Seegene\u00ae, Seoul, Korea), and 97% (88% to 99%) for the VIASURE macrolide resistance-associated mutations (23SrRNA) Real time PCR detection kit (Certest Biotec, Zaragoza, Spain). The clinical specificity was 100% (94% to 100%) for Allplex and VIASURE assays and 95% (86% to 99%) for SpeeDx assay. The results arising from this study are cause for strong consideration for the implementation of rapid real-time PCR assays in clinical diagnosis laboratories to eliminate treatment failure and transmission as soon as possible.<\/jats:p>","DOI":"10.3390\/ijms24087218","type":"journal-article","created":{"date-parts":[[2023,4,14]],"date-time":"2023-04-14T02:28:12Z","timestamp":1681439292000},"page":"7218","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Retrospective and Comparative Study of Three Molecular Assays for the Macrolide Resistance Detection in Mycoplasma genitalium Positive Urogenital Specimens"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5750-3643","authenticated-orcid":false,"given":"Mar\u00eda Paz","family":"Peris","sequence":"first","affiliation":[{"name":"Instituto de Investigaci\u00f3n Sanitaria Arag\u00f3n, 50009 Zaragoza, Spain"},{"name":"Department of Animal Pathology, Faculty of Veterinary, University of Zaragoza, 50013 Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Blanca","family":"Dehesa","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Pediatrics, Radiology, and Public Health, Faculty of Medicine, University of Zaragoza, 50009 Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henar","family":"Alonso","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Pediatrics, Radiology, and Public Health, Faculty of Medicine, University of Zaragoza, 50009 Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6132-893X","authenticated-orcid":false,"given":"Cristina","family":"Escolar","sequence":"additional","affiliation":[{"name":"Department of Animal Production and Food Science, Faculty of Veterinary, University of Zaragoza, 50013 Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3503-2331","authenticated-orcid":false,"given":"Laura","family":"Clusa","sequence":"additional","affiliation":[{"name":"Instituto de Investigaci\u00f3n Sanitaria Arag\u00f3n, 50009 Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9932-0124","authenticated-orcid":false,"given":"Miriam","family":"Latorre-Mill\u00e1n","sequence":"additional","affiliation":[{"name":"Instituto de Investigaci\u00f3n Sanitaria Arag\u00f3n, 50009 Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"Rezusta","sequence":"additional","affiliation":[{"name":"Instituto de Investigaci\u00f3n Sanitaria Arag\u00f3n, 50009 Zaragoza, Spain"},{"name":"Miguel Servet University Hospital, Microbiology, 50009 Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana","family":"Milagro","sequence":"additional","affiliation":[{"name":"Instituto de Investigaci\u00f3n Sanitaria Arag\u00f3n, 50009 Zaragoza, Spain"},{"name":"Miguel Servet University Hospital, Microbiology, 50009 Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"80","DOI":"10.15585\/mmwr.rr7004a1","article-title":"Sexually Transmitted Infections Treatment Guidelines","volume":"70","author":"Workowski","year":"2021","journal-title":"MMWR Recomm.
