To investigate these patterns, serovar determination was performed on chlamydia-positive samples from two community-based cohort studies of HIV-positive and HIV-negative MSM in Sydney, Australia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>From January 2005 to June 2007 all positive<jats:italic>C trachomatis<\/jats:italic>pharyngeal, urine and anal samples were evaluated. The serovar of each<jats:italic>C trachomatis<\/jats:italic>infection was determined by<jats:italic>omp1<\/jats:italic>gene sequencing with confirmatory quantitative PCR screening.

Seven samples were not able to be typed. Site-specific symptoms were reported by fewer than 10% of participants diagnosed with pharyngeal and anogenital chlamydia. The most commonly identified serovars were serovar D (n=32, 59.3%, 95% CI 45.0 to 72.4), followed by serovar G (n=11, 20.4%, 95% CI 10.6 to 33.5) and serovar J (n=5, 9.3%, 95% CI 3.1 to 20.3). Only one lymphogranuloma venereum serovar was identified (L2b).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>This community-based study found a similar distribution of chlamydia serovars to that observed among Australian community-based MSM several years ago, and serovar distribution recently observed among predominantly symptomatic MSM at a Sydney clinic. These findings suggest little change in<jats:italic>C trachomatis<\/jats:italic>serovar distribution in Australian MSM over the past decade and a lack of correlation of specific chlamydia serovars with anogenital symptoms among MSM.<\/jats:p><\/jats:sec>","DOI":"10.1136\/sextrans-2011-050062","type":"journal-article","created":{"date-parts":[[2011,8,4]],"date-time":"2011-08-04T01:05:23Z","timestamp":1312419923000},"page":"501-502","source":"Crossref","is-referenced-by-count":6,"title":["<i>Chlamydia trachomatis<\/i>serovars in community-based HIV-positive and HIV-negative men who have sex with men in Sydney, Australia"],"prefix":"10.1136","volume":"87","author":[{"given":"D J","family":"Templeton","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J","family":"Twin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F","family":"Jin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A E","family":"Grulich","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S M","family":"Garland","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S N","family":"Tabrizi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2011,8,3]]},"reference":[{"key":"2024051319031033000_87.6.501.1","doi-asserted-by":"publisher","DOI":"10.1136\/sti.2006.021915"},{"key":"2024051319031033000_87.6.501.2","doi-asserted-by":"publisher","DOI":"10.1136\/sti.2007.025684"},{"key":"2024051319031033000_87.6.501.3","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.02308-09"},{"key":"2024051319031033000_87.6.501.4","doi-asserted-by":"crossref","first-page":"279","DOI":"10.1097\/OLQ.0b013e3181fc6944","article-title":"Chlamydia trachomatis genotypes among men who have sex with men in Australia","volume":"38","author":"Twin","year":"2011","journal-title":"Sex Transm Dis"},{"key":"2024051319031033000_87.6.501.5","doi-asserted-by":"publisher","DOI":"10.1097\/OLQ.0b013e3181e78389"},{"key":"2024051319031033000_87.6.501.6","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.42.6.2596-2601.2004"},{"key":"2024051319031033000_87.6.501.7","doi-asserted-by":"crossref","first-page":"189","DOI":"10.1097\/00007435-200204000-00001","article-title":"Epidemiology of anorectal chlamydial and gonococcal infections among men having sex with men in Seattle: utilizing serovar and auxotype strain typing","volume":"29","author":"Geisler","year":"2002","journal-title":"Sex Transm Dis"},{"key":"2024051319031033000_87.6.501.8","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.00574-06"}],"container-title":["Sexually Transmitted Infections"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/sextrans-2011-050062","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,14]],"date-time":"2024-05-14T02:03:49Z","timestamp":1715652229000},"score":1,"resource":{"primary":{"URL":"https:\/\/sti.bmj.com\/lookup\/doi\/10.1136\/sextrans-2011-050062"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,8,3]]},"references-count":8,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2011,9,13]]},"published-print":{"date-parts":[[2011,10]]}},"alternative-id":["10.1136\/sextrans-2011-050062"],"URL":"https:\/\/doi.org\/10.1136\/sextrans-2011-050062","relation":{},"ISSN":["1368-4973","1472-3263"],"issn-type":[{"value":"1368-4973","type":"print"},{"value":"1472-3263","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,8,3]]}}}
