RESUMO
While ceftriaxone remains the first-line treatment for gonorrhoea, the US CDC recommended cefixime as a second-line treatment in 2021. We tested 1176 Neisseria gonorrhoeae isolates among clients attending the Melbourne Sexual Health Centre in 2021-2022. The prevalence of cefixime resistance was 6.3% (74/1176), azithromycin resistance was 4.9% (58/1176) and ceftriaxone resistance was 0% (0/1176). Cefixime resistance was the highest among women (16.4%, 10/61), followed by men-who-have-sex-with-women (6.4%, 7/109), and men-who-have-sex-with-men (5.8%, 57/982). The prevalence of cefixime-resistant N. gonorrhoeae exceeds the threshold of the 5% resistance level recommended by the World Health Organization; and thus, cefixime treatment would have limited benefits in Australia.
RESUMO
BACKGROUND: Few studies investigate group sex among heterosexuals. The aim of this study was to provide an exploration of characteristics and practices among heterosexual men and women who engage in group sex. METHOD: We conducted a cross-sectional survey between May 2019 and March 2020 among heterosexual men and women attending a sexual health clinic in Melbourne, Australia. Participants were asked whether they had participated in group sex (sex involving more than two participants) in the past 3months, the size of the most recent event, sexual activities in which they engaged, and condom use. RESULTS: Of 3277 heterosexuals surveyed (1509 women and 1768 men), the mean age was 29.9years (s.d. 8.8) and more than half (56.0%, n =1834) were born outside Australia. One in 20 participants (5.4%) had engaged in group sex in the past 3months with the number of events ranging 1-10times. Kissing was the most common activity in group sex, and women were significantly more likely to kiss a same-sex partner than men. Overall, of 165 participants who engaged in vaginal sex, 57 (34.5%) reported always using condoms and changing condoms between consecutive partners. Of the 100 men and women who had condomless vaginal sex, 79 (79.0%) received or performed fellatio after condomless vaginal sex. CONCLUSION: About two-thirds of heterosexuals who engaged in group sex neither used condoms nor changed condoms between partners in the most recent group sex event. Safe sex messages on changing condoms between partners and between sexual activities should be reinforced for sexually transmitted infections prevention.

BACKGROUND: The first mpox case was reported in May 2022 in Australia. Most cases have been diagnosed in men who have sex with men (MSM). This study aimed to examine community understanding of mpox, attitudes towards vaccination, and potential changes in sexual practices surrounding the mpox outbreak among MSM and transgender people in Victoria, Australia. METHODS: Participants were recruited from sexual health clinics and communities in Victoria, Australia, in August-October 2022. Participants were asked about their understanding and knowledge of mpox, vaccination uptake and intentions to change sexual practices. Univariable and multivariable logistic regression was performed to examine the factors associated with mpox vaccine uptake. RESULTS: Most participants (97.8%, 525/537) had heard about mpox and 10.5% (55/525) knew someone who had had mpox. Of the 12 mpox knowledge questions, the median score of correct answers was 10 (IQR=8-11) out of a maximum of 12. More than a third (36.6%, 191/522) had been vaccinated against mpox. MSM who had a good knowledge of mpox had the highest odds of receiving mpox vaccine compared with those who had poor knowledge (aOR=4.05; 95% CI: 1.54-10.61). To prevent mpox, half reported they would reduce having sex with casual partners, stop having chemsex (used drugs for the purpose of sex), stop attending sex-on-premises-venues, and stop having group sex. A quarter reported they would increase condom use for anal sex. CONCLUSIONS: One-third of high-risk participants and a substantial proportion of participants intended to reduce or stop certain practices, which may explain the large reduction in mpox cases.
RESUMO
Improved treatment and prevention strategies, such as antimicrobial mouthwashes, may be important for addressing the public health threat of antimicrobial-resistant Neisseria gonorrhoeae. Here, we describe the activity of seven common antibacterial mouthwashes and antiseptics against N. gonorrhoeae isolates, incorporating the use of a human saliva test matrix. Our data demonstrate that antibacterial mouthwashes and antiseptics vary in their ability to inhibit the in vitro growth of N. gonorrhoeae and saliva may impact this inhibitory activity.

BACKGROUND: Asian-born gay, bisexual and other men who have sex with men (gbMSM) newly arrived in Australia are more than four times as likely than their Australian-born counterparts to be diagnosed with incident HIV. Our aim was to explore experiences of Asian-born gbMSM newly arrived in Australia and attending a sexual health centre with regards to their knowledge of and preference for HIV prevention strategies. RESULTS: Twenty-four gbMSM aged 20-30 years attending Melbourne Sexual Health Centre who were born in Asia and arrived in Australia in the preceding four years, participated in semi-structured face-to-face interviews from 8th May 2019 and 23rd December 2019. Men were excluded if they were living with HIV. Interviews were recorded, transcribed verbatim and analysed thematically. Men reported little knowledge of HIV prevention strategies outside of condom use prior to coming to Australia. Although participants reported basic knowledge of HIV transmission and treatment, exposure to sexual identity and HIV-related stigma in their countries of birth meant they imagined a HIV diagnosis would be devastating. Most relied on condoms to stay HIV negative however their consistency of use varied. Seven men were on pre-exposure prophylaxis (PrEP); all but one started PrEP after coming to Australia. Many indicated interest in PrEP but described it as too expensive given they do not have access to government-subsidized healthcare. Sexual health counselling and connections with LGBTQI community groups appeared to facilitate PrEP and consistent condom use. CONCLUSIONS: Asian-born gbMSM newly-arrived to Australia may have limited knowledge of HIV prevention strategies aside from condom use. Increased connections with sexual health services and LGBTQI communities may facilitate more effective HIV prevention strategies.

OBJECTIVES: To compare the usability and acceptability of oral fluid- and blood-based HIV self-test kits among men who have sex with men in Australia. DESIGN: Randomised crossover trial. SETTING, PARTICIPANTS: Gay, bisexual, and other men aged 18 years or older who have sex with men, who attended two metropolitan sexual health clinics in Sydney and Melbourne, 7 January - 10 December 2019. MAIN OUTCOME MEASURES: Ease of use of HIV self-test kits; preferred HIV self-test type; difficulties encountered during HIV self-testing. RESULTS: 170 men were recruited (median age, 34 years; interquartile range, 29-43 years); 144 identified as gay (85%), 96 were born outside Australia (57%). Participants were more likely to report the oral fluid HIV self-test was easy to use than the blood-based self-test (oral fluid, 99%; blood, 86%; odds ratio [OR], 3.0; 95% confidence interval [CI], 1.4-6.6). The oral fluid test was preferred by 98 participants (58%; 95% CI, 50-65%), the blood-based test by 69 (41%; 95% CI, 33-48%). Difficulties with the oral fluid test kit identified by observing nurses included problems placing the buffer solution into the stand (40 of 170 participants, 24%) and not swabbing both gums (23 of 169, 14%); difficulties with the blood-based test kit included problems filling the device test channel (69 of 170, 41%) and squeezing the finger firmly enough to generate a blood drop (42 of 170, 25%). No participant received an invalid result with the oral fluid self-test; two of 162 participants (1%) received invalid results with the blood self-test. After adjusting for age, education level, and ethnic background, characteristics associated with higher odds of using HIV self-testing in the future were overseas birth (adjusted OR, 3.07; 95% CI, 1.42-6.64), and self-evaluated ease of use and confidence in using the kits. CONCLUSION: It is important to provide options for obtaining both oral fluid- and blood-based HIV self-tests. The usability and acceptability of both kits were high, but the ease of use and perceived accuracy influenced test kit preference.

Behavioral economics and its applied branch "nudging" can improve individual choices in various health care settings. However, there is a paucity of research using nudges to improve regular testing for HIV and other sexually transmitted infections (STIs). The study examined which reminder system and message type men who have sex with men (MSM) preferred to remind them to undergo regular 3-monthly HIV and STI testing. A cross-sectional survey study was conducted among MSM attending a sexual health clinic in Melbourne, Australia between 13 January and 5 March 2020, exploring the preferred method of reminder and framing of the message. Descriptive statistics and logistic regression were used to analyze the data. A total of 309 responses were received. The majority of the participants (90%) preferred short messaging service (SMS) as the reminder method for HIV/STI testing compared to other types (e.g., email or instant messaging). More than a third of the participants (45%) showed a preference for a neutrally framed reminder message (Your next check-up is now due. Please phone for an appointment), while one-third (35%) preferred a personalized message (Hi [first name], you are due for your next check-up. Please phone for an appointment). Younger men were more likely to favor positive framed messages than older men who favored neutrally framed messages (p < .01). SMS was the preferred reminder method for regular HIV/STI testing. Reminder messages that were neutrally framed, personalized or positive framed messages were preferred over negative or social norm messages.

BACKGROUND: Kissing may be a risk factor for gonorrhoea. Past studies have focused on male kissing partners among men who have sex with men (MSM). This study aimed to examine the kissing practices of MSM who kiss male and female partners. METHODS: We conducted a cross-sectional survey at the Melbourne Sexual Health Centre (MSHC) between March and April 2019. Men attending the MSHC, aged ≥16years who reported any sexual contact with another man in the previous 12months were invited to participate in the survey. Data about the number of kissing-only (kissing without sex), kissing-with-sex, and sex-only (having sex without kissing) partners in the previous 3months were collected. Men were asked to report the number of male and female partners separately. RESULTS: There were 357 MSM included in the survey. Most men (97.2%, n =347) had kissed or had sex with another man, whereas 16.0% (n =57) had kissed or had sex with a female partner in the previous 3months. Of the 57 men, 26.3% (n =15) had only kissed a female partner without having sex. The mean number of male partners for kissing-only was 5.5 (s.d.=6.6), kissing-with-sex was 5.0 (s.d.=6.6) and sex-only was 3.9 (s.d.=4.3). The mean number of female partners for kissing-only was 4.2 (s.d.=6.9), kissing-with-sex was 3.8 (s.d.=4.9) and sex-only was 3.2 (s.d.=3.4). CONCLUSION: MSM not only kiss men in the absence of sex, but also kiss women in the absence of sex. Gonorrhoea could be transmitted between MSM and women via kissing in the absence of sex.

We conducted a survey among 40 clinicians working at the Melbourne Sexual Health Centre in November 2021. We asked clinicians how they discussed cervical screening with their clients. All clinicians used the term 'Cervical Screening Test (CST)' when discussing cervical cancer screening with clients. However, 19 clinicians (48%) also used the term 'Pap smear', particularly among older women as they were more familiar with Pap smear than CST. Twenty-five (63%) clinicians believed that clients did not understand the difference between Pap smears and CST. Further education is required to improve the understanding between the terminologies.

BACKGROUND: There have been limited studies of group sex among heterosexual individuals. This study aimed to explore the factors associated with group sex among heterosexual males and females to improve risk assessment guidelines and inform sexually transmitted infection (STI) screening requirements. METHODS: A cross-sectional survey was conducted among heterosexual males and females aged ≥16 years attending the Melbourne Sexual Health Centre between March and April 2019. The survey asked about group sex participation, methods used to meet sexual partners, number of casual and/or regular partners, and injection drug use (IDU) in the previous 3 months. HIV and STI (chlamydia, gonorrhoea, syphilis) diagnoses were extracted. A multivariable logistic regression was conducted to identify the factors associated with group sex participation. RESULTS: A total of 698 participants (325 males, 373 females) were included and 4.7% (33/698) had participated in group sex in the previous 3 months. The proportion who participated in group sex increased with age (2.1% in 16-24 years, 5.5% in 25-34 years, 7.8% in ≥35 years, p trend =0.010). Meeting partners at sex venues (e.g. brothels) was associated with the highest odds of participating in group sex (aOR=5.74, 95% CI: 1.20-27.44), followed by dating apps (aOR=2.99, 95% CI: 1.36-6.58), friends/family (aOR=2.99, 95% CI: 1.34-6.69) and social venues (e.g. bar) (aOR=2.73, 95% CI: 1.18-6.30). Group sex was strongly associated with STI positivity (aOR=6.24, 95% CI: 2.41-16.13). There was no association between group sex and sex, casual and/or regular partners, HIV positivity or IDU. CONCLUSION: Heterosexual individuals participating in group sex had a six-fold risk of testing positive for STIs. Including group sex in a sexual history is useful to determine STI risk and inform testing practices. Safe sex messages on group sex that are delivered through multiple methods (e.g. at sex venues, social venues and dating apps simultaneously) would be beneficial.

Self-taking oropharyngeal swabs for sexually transmitted infections such as gonorrhoea and chlamydia has become more common during the COVID-19 pandemic to minimise the risk to healthcare workers. However, there have been no standardised guidelines on sampling time for taking an oropharyngeal swab for gonorrhoea and chlamydia testing. We recruited 215 participants at the Melbourne Sexual Health Centre, Australia, between November 2021 and January 2022. We asked participants to report the time they spent on self-taking the oropharyngeal swab. The median self-taking sampling time was 8s (IQR=5-12), and the time did not differ between oropharyngeal gonorrhoea positivity (P =0.570) and oropharyngeal chlamydia positivity (P =0.457).

OBJECTIVES: This prospective cohort study aimed to determine the natural history and incidence of oropharyngeal gonorrhoea and chlamydia among a cohort of men who have sex with men (MSM) over a 12-week period, and to examine risk factors associated with incident oropharyngeal infections. METHODS: MSM either aged ≥18 years and had a diagnosis of oropharyngeal gonorrhoea by nucleic acid amplification test (NAAT) in the past 3 months or aged 18-35 years who were HIV-negative taking pre-exposure prophylaxis (PrEP) were eligible for this study. Enrolled men were followed up for 12 weeks. Oropharyngeal swabs were collected at week 0 (baseline) and week 12 (end of study). Between these time points, weekly saliva specimens and the number of tongue kissing, penile-oral and insertive rimming partners were collected by post. Oropharyngeal swabs and saliva specimens were tested by NAAT for Neisseria gonorrhoeae and Chlamydia trachomatis. Poisson regression was performed to examine the risk factors (weekly number of partners) associated with incident oropharyngeal gonorrhoea. RESULTS: A total of 100 MSM were recruited. The incidence of oropharyngeal gonorrhoea and chlamydia was 62 (95% CI 37 to 105) and 9 (95% CI 2 to 35)/100 person-years, respectively. The median duration of incident oropharyngeal infection with gonorrhoea was 28 days (IQR=21-36, n=7). The incidence rate ratio (IRR) for oropharyngeal gonorrhoea increased with an increased number of kissing partners (IRR=1.08; 95% CI 1.03 to 1.12) an increased number of penile-oral sex partners (IRR=1.07, 95% CI 1.01 to 1.14) but not with an increased number of insertive rimming partners (IRR=1.11, 95% CI 0.96 to 1.29) or other demographic factors. The IRR and duration of incident oropharyngeal chlamydia were not calculated due to the small number of cases (n=2). CONCLUSIONS: MSM have a high incidence of oropharyngeal gonorrhoea and the median duration of infection was less than 3 months.

BACKGROUND: Most research focuses on individual selling sex but very few on paying for sex. This study aimed to determine the proportion of males and females who paid for sex and associated factors. METHODS: We conducted a short survey at the Melbourne Sexual Health Centre between March and April 2019, which included a question on whether they had paid for sex in the past 3 months. The proportion of individuals who had paid for sex was calculated by sex and sexual orientation. Univariable and multivariable logistic regression models were conducted to identify individual's factors (e.g., demographics, sexual orientation, and HIV/sexually transmitted infection [STI] positivity) associated with paying for sex in the past 3 months. RESULTS: The proportion who reported paying for sex in the past 3 months was 12.2% (42/345) among heterosexual males, followed by 6.4% (23/357) among men who have sex with men (MSM) and 0.2% (1/430) among females. HIV status, preexposure prophylaxis use, and sexual orientation were not associated with paying for sex among MSM. No MSM living with HIV reported paying for sex in the past 3 months. There was a significant association between paying for sex and gonorrhea (odds ratio, 2.84; 95% confidence interval, 1.05-7.71; P = 0.041) but not HIV, syphilis, and chlamydia among MSM. HIV/STI was not associated with paying for sex among heterosexual males. CONCLUSIONS: Paying for sex was more commonly reported among heterosexual males, followed by MSM. Females were very unlikely to pay for sex. There was a limited association between HIV/STI diagnosis and paying for sex among males.

Screening for Chlamydia trachomatis and Neisseria gonorrhoeae at the pharyngeal, urogenital, and anorectal sites is recommended for men who have sex with men (MSM). Combining the three individual-site samples into a single pooled sample could result in significant cost savings, provided there is no significant sensitivity reduction. The aim of this study was to examine the sensitivity of pooled samples for detecting chlamydia and gonorrhea in asymptomatic MSM using a nucleic acid amplification test. Asymptomatic MSM who tested positive for chlamydia or gonorrhoea were invited to participate. Paired samples were obtained from participants prior to administration of treatment. To form the pooled sample, the anorectal swab was agitated in the urine specimen transport tube and then discarded. The pharyngeal swab and 2 ml of urine sample were then added to the tube. The difference in sensitivity between testing of pooled samples and individual-site testing was calculated against an expanded gold standard, where an individual is considered positive if either pooled-sample or individual-site testing returns a positive result. All samples were tested using the Aptima Combo 2 assay. A total of 162 MSM were enrolled in the study. Sensitivities of pooled-sample testing were 86% (94/109; 95% confidence interval [CI], 79 to 92%]) for chlamydia and 91% (73/80; 95% CI, 83 to 96%) for gonorrhea. The sensitivity reduction was significant for chlamydia (P = 0.02) but not for gonorrhea (P = 0.34). Pooling caused 22 infections (15 chlamydia and 7 gonorrhoea) to be missed, and the majority were single-site infections (19/22). Pooling urogenital and extragenital samples from asymptomatic MSM reduced the sensitivity of detection by approximately 10% for chlamydia but not for gonorrhea.

The coronavirus disease 2019 (COVID-19) pandemic has led many clinics to move from clinician-collected to self-collected oropharyngeal swabs for the detection of sexually transmitted infections (STIs). Before this change, however, self-collection was used primarily for genital and anorectal infections, with only limited studies on the performance of self-collection of oropharyngeal swabs for oropharyngeal STI detection. The Melbourne Sexual Health Centre (MSHC) changed from clinician-collected to self-collected oropharyngeal swabs for oropharyngeal gonorrhea and chlamydia screening on 16 March 2020 in order to reduce health care worker risk during the COVID-19 pandemic. We compared the proportions of valid and positive samples for gonorrhea and chlamydia among men who have sex with men (MSM) in two time periods; the clinician collection period, between 20 January and 15 March 2020, and the self-collection period, between 16 March and 8 May 2020. A total of 4,097 oropharyngeal swabs were included. The proportion of oropharyngeal swabs with equivocal or invalid results for Neisseria gonorrhoeae was higher in the self-collection period (1.6% [24/1,497]) than in the clinician collection period (0.9% [23/2,600]) (P = 0.038), but the proportions did not differ for the detection of Chlamydia trachomatis The positivity rates of oropharyngeal N. gonorrhoeae (adjusted prevalence ratio [PR], 1.07 [95% confidence interval {CI}, 0.85 to 1.34]) (P = 0.583) and oropharyngeal C. trachomatis (adjusted PR, 0.84 [95% CI, 0.51 to 1.39]) (P = 0.504) specimens did not differ between the two periods. Self-collected oropharyngeal swabs for the detection of N. gonorrhoeae and C. trachomatis have acceptable performance characteristics and, importantly, reduce health care worker exposure to respiratory infections.

OBJECTIVES: Oropharyngeal gonorrhoea is increasing among men who have sex with men and is commonly found in the tonsils and at the posterior pharyngeal wall. To address this rise, investigators are currently trialling mouthwash to prevent oropharyngeal gonorrhoea. We aimed to determine which parts of the oropharynx were reached by different methods of mouthwash use (oral rinse, oral gargle and oral spray). METHODS: Twenty staff at Melbourne Sexual Health Centre participated in the study from March to May 2018. Participants were asked to use mouthwash mixed with food dye, by three application methods on three separate days: oral rinse (15 s and 60 s), oral gargle (15 s and 60 s) and oral spray (10 and 20 times). Photographs were taken after using each method. Three authors assessed the photographs of seven anatomical areas (tongue base, soft palate, uvula, anterior tonsillar pillar, posterior tonsillar pillar, tonsil, posterior pharyngeal wall) independently and scored the dye coverage from 0% to 100%. Scores were then averaged. RESULTS: The mean coverage at the sites ranged from 2 to 100. At the posterior pharyngeal wall, spraying 10 times had the highest mean coverage (29%) and was higher than a 15 s rinse (2%, p=0.001) or a 15 s gargle (8%, p=0.016). At the tonsils, there was no difference in mean coverage between spray and gargle at any dosage, but spraying 20 times had a higher mean coverage than a 15 s rinse (42% vs 12%, p=0.012). CONCLUSION: Overall, spray is more effective at reaching the tonsils and posterior pharyngeal wall compared with rinse and gargle. If mouthwash is effective in preventing oropharyngeal gonorrhoea, application methods that have greater coverage may be more efficacious.

Gonorrhoea cases in women have been rising in Australia in the 2010s but the cause of the increase is not well understood. This cross-sectional study aimed to describe the characteristics of genital gonorrhoea infection in women attending the Melbourne Sexual Health Centre, Australia. Gonorrhoea cases were diagnosed by nucleic acid amplification test (NAAT) and/or culture. Genitourinary specimens were obtained in 12 869 clinic visits in women aged 16 years or above between August 2017 and August 2018. Genital gonorrhoea was detected in 142 (1.1%) of the visits. Almost half of the cases were asymptomatic, 47.9% [95% confidence interval (CI) 39.8-56.1%]; yellow, green or pus-like vaginal discharge was present in 11.3% (95% CI 7.0-17.6%) and other genital symptoms in 40.8% (95% CI 33.1-49.1%) of the cases. The mean time between last sexual contact and onset of symptoms was 7.3 days and between the onset of symptoms to presentation to the clinic was 12.1 days. Half of the cases of genital gonorrhoea among women are asymptomatic and these cases would have been missed by testing of only symptomatic women. Further epidemiological and behavioural research is required to understand the temporal changes in sexual practices among women in Australia.

BACKGROUND: Asymptomatic screening for gonorrhoea in heterosexual men is currently not recommended in many countries including Australia, given the prevalence is relatively low in the heterosexual population. We aimed to determine the proportion of urethral gonorrhoea cases among heterosexual men attending a sexual health clinic that was asymptomatic and symptomatic, the time since last sexual contact to the onset of symptoms and the time to clinic presentation following the onset of symptoms. METHODS: This was a cross-sectional study that included heterosexual men aged 16 years or above attending the Melbourne Sexual Health Centre (MSHC) in Australia between August 2017 and August 2018. Gonorrhoea cases were diagnosed by nucleic acid amplification testing (NAAT) and/or culture. Descriptive analyses were conducted for all gonorrhoea cases including demographic characteristics, recent sexual practices, reported urethral symptoms and duration, sexual contact with a person diagnosed with gonorrhoea, investigations performed and laboratory results. RESULTS: There were 116 confirmed cases of urethral gonorrhoea in heterosexual men over the study period of which 6.0% (95% CI: 2.7-12.1%) were asymptomatic. Typical urethral discharge was present in 80.2% (95% CI: 71.9-86.5%) of men. The mean time between last sexual contact and the onset of symptoms was 7.0 days, and between the onset of symptoms to presentation to the clinic was 5.6 days. CONCLUSIONS: A small proportion of heterosexual men with urethral gonorrhoea do not have any symptoms.

Background Sexually transmissible infections (STIs) are rising among female sex workers (FSW) in Australia. The rise might be explained by changes in sexual practices; however, there is limited behavioural data available. This study aimed to explore the current sexual practices among FSW in Melbourne. METHODS: This cross-sectional study was conducted among FSW at Melbourne Sexual Health Centre between September 2017 and March 2018. Participants were asked about current sexual practices with male clients in an average working week. The frequency and proportion of each sexual practice was calculated. RESULTS: There were 180 questionnaires included in the analysis. The median age of the FSW was 28 years (interquartile range [IQR]: 25-34). Most FSW (80.6%) worked in brothels. In an average working week, FSW had a median of 10 (IQR: 7-20) male clients. The most common sexual practices included: vaginal sex (98.3%), fellatio (97.2%), cunnilingus (92.2%) and tongue-kissing (83.7%). FSW had a median number of 10 (IQR: 6-18) vaginal, 10 (IQR: 5-18) fellatio, 7 (IQR: 2-10) cunnilingus and 6 (IQR: 2-10) tongue-kissing clients. Consistent condom use with all clients was highest for vaginal sex (97.1%), followed by anal sex (92.3%), then fellatio (78.9%). Only 3.1% used dental dams consistently for cunnilingus. CONCLUSION: Consistent condom use with all clients was high among FSWs, especially for vaginal and anal sex. However, one-fifth of FSW had condomless fellatio during an average working week. Tongue-kissing was more common than previously published. Peer-led sexual health education on safe sex practice for FSW is of high importance.

The aim of this study was to determine whether Chlamydia trachomatis could be detected in saliva and if infection is specific to an anatomical site in the oropharynx. Men who have sex with men (MSM) who were diagnosed with oropharyngeal chlamydia at the Melbourne Sexual Health Centre in 2017-2018 were invited to participate upon returning for treatment. Swabs at the tonsillar fossae and posterior oropharynx and a saliva sample were collected. Throat samples were tested for C. trachomatis by the Aptima Combo 2 assay. The bacterial loads of C. trachomatis in all samples were assessed by quantitative PCR (qPCR) detecting the ompA gene. We calculated the positivity and bacterial load of C. trachomatis for all samples. Forty-two MSM were included. The median age was 28 years (interquartile range [IQR], 24 to 33 years). Thirty-two participants (76.2%; 95% confidence interval [CI], 60.5% to 87.9%) had C. trachomatis detected by qPCR at both the tonsillar fossae and the posterior oropharynx, followed by 9.5% (n = 4; 95% CI, 2.7% to 22.6%) positive at the posterior oropharynx only and 4.8% (n = 2; 95% CI, 0.58% to 16.2%) positive at the tonsillar fossae only. Twenty-nine MSM had C. trachomatis detected in saliva (69.0%; 95% CI, 52.9% to 82.3%). The median C. trachomatis load in saliva was 446 copies/ml (IQR, 204 to 1,390 copies/ml), that in the tonsillar fossae was 893 copies/swab (IQR, 390 to 13,224 copies/ml), and that in the posterior oropharynx was 1,204 copies/swab (IQR, 330 to 16,211). There was no significant difference in C. trachomatis load between the tonsillar fossae and the posterior oropharynx (P = 0.119). Among MSM with oropharyngeal chlamydia, nearly three-quarters had chlamydia DNA detected in saliva, although the viability and implications for transmission are unknown.
