This retrospective study investigated the distribution of selected tetracycline- and \u03b2-lactam resistance genes in the oropharyngeal and anorectal mucosa of MSM attending a sexually transmitted infection (STI) clinic and explored their association with demographic and behavioral variables. In early 2025, 49 MSM attending the STI Clinic of IRCCS Azienda Ospedaliero Universitaria in Bologna, Italy, were enrolled. Participants completed a questionnaire and underwent pharyngeal and anorectal swabbing. End-point polymerase chain reaction assays were used to detect tetracycline resistance genes (\n                    <jats:italic toggle=\"yes\">tet(X), tet(O), tet(W), tet(Q)<\/jats:italic>\n                    ) and \u03b2-lactamase genes (\n                    <jats:italic toggle=\"yes\">blaOXA-2, blaTEM, blaSHV, blaCTX-M<\/jats:italic>\n                    ). Overall, 20\/49 participants (40.8%) reported antibiotic use in the previous 6 months, and 19\/49 (38.7%) reported having &gt;6 sexual partners during the same period. At least one tetracycline resistance gene was detected in all participants (49\/49; 100%) at both anatomical sites. In contrast, at least one \u03b2-lactamase gene was identified in 38\/49 (77.6%) oropharyngeal samples and 42\/49 (85.7%) anorectal samples. No statistically significant associations were observed between \u03b2-lactamase gene carriage and the variables analyzed. However, in the oropharyngeal mucosa, a numerically higher prevalence was observed among individuals reporting &gt;6 sexual partners, although the difference was not statistically significant (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    = 0.061). The oropharyngeal and anorectal mucosae of MSM may represent reservoirs of antimicrobial resistance genes. These findings provide descriptive evidence of the widespread distribution of resistance determinants and highlight the need for further studies to clarify their drivers and clinical relevance.\n                  <\/jats:p>","DOI":"10.1177\/10766294261457995","type":"journal-article","created":{"date-parts":[[2026,6,8]],"date-time":"2026-06-08T11:57:46Z","timestamp":1780919866000},"page":"382-386","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Distribution of Tetracycline and \u03b2-Lactam Resistance Genes in the Oropharyngeal and Anorectal Mucosa of Men Who Have Sex with Men: An Exploratory Study"],"prefix":"10.1177","volume":"32","author":[{"given":"Marielle Eziekelle","family":"Djusse","sequence":"first","affiliation":[{"name":"Department of Medical and Surgical Sciences, Section of Microbiology, Alma Mater Studiorum\u2014University of Bologna, Bologna, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valeria","family":"Gaspari","sequence":"additional","affiliation":[{"name":"Dermatology Unit, IRCCS Azienda Ospedaliero\u2014Universitaria di Bologna, Bologna, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7253-8799","authenticated-orcid":false,"given":"Claudio","family":"Foschi","sequence":"additional","affiliation":[{"name":"Department of Medical and Surgical Sciences, Section of Microbiology, Alma Mater Studiorum\u2014University of Bologna, Bologna, Italy."},{"name":"Microbiology Unit, IRCCS Azienda Ospedaliero\u2014Universitaria di Bologna, Bologna, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonella","family":"Marangoni","sequence":"additional","affiliation":[{"name":"Department of Medical and Surgical Sciences, Section of Microbiology, Alma Mater Studiorum\u2014University of Bologna, Bologna, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,6,8]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/09564624241255163"},{"key":"e_1_3_3_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jinf.2023.02.006"},{"key":"e_1_3_3_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/0956462420957519"},{"key":"e_1_3_3_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41591-024-03274-2"},{"key":"e_1_3_3_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mehy.2014.04.030"},{"key":"e_1_3_3_7_1","doi-asserted-by":"publisher","DOI":"10.3390\/genes11091088"},{"key":"e_1_3_3_8_1","doi-asserted-by":"publisher","DOI":"10.1080\/19490976.2019.1700755"},{"key":"e_1_3_3_9_1","doi-asserted-by":"publisher","DOI":"10.1093\/infdis\/jiaa497"},{"key":"e_1_3_3_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijantimicag.2023.106716"},{"key":"e_1_3_3_11_1","doi-asserted-by":"publisher","DOI":"10.1093\/cid\/ciac218"},{"key":"e_1_3_3_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cmi.2024.03.016"}],"container-title":["Microbial Drug Resistance"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/10766294261457995","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/10766294261457995","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/10766294261457995","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T23:18:26Z","timestamp":1786058306000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/10766294261457995"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6,8]]},"references-count":11,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2026,9,1]]}},"alternative-id":["10.1177\/10766294261457995"],"URL":"https:\/\/doi.org\/10.1177\/10766294261457995","relation":{},"ISSN":["1076-6294","1931-8448"],"issn-type":[{"value":"1076-6294","type":"print"},{"value":"1931-8448","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,6,8]]}}}
