Prevotella and Gardnerella Are Associated With Treatment Failure Following First-line Antibiotics for Bacterial Vaginosis.

Background: Bacterial vaginosis (BV) is a common vaginal dysbiosis that often recurs following first-line antibiotics. We investigated if vaginal microbiota composition was associated with BV recurrence.

Methods: We analyzed samples and data from 121 women who participated in 3 published trials evaluating novel interventions for improving BV cure, including concurrent antibiotic treatment of regular sexual partners (RSPs).

gyrA Mutations in Mycoplasma genitalium and Their Contribution to Moxifloxacin Failure: Time for the Next Generation of Resistance-Guided Therapy.

Background: Although single nucleotide polymorphisms (SNPs) in Mycoplasma genitalium parC contribute to fluoroquinolone treatment failure, data are limited for the homologous gene, gyrA. This study investigated the prevalence of gyrA SNPs and their contribution to fluoroquinolone failure.

Methods: Samples from 411 patients (male and female) undergoing treatment for M.

The Urethral Microbiota of Men with and without Idiopathic Urethritis.

Nongonococcal urethritis (NGU) is a common genital tract syndrome in men, and up to 50% of cases are considered idiopathic, i.e., no etiological agent is identified.

A Prospective, Open-Label Pilot Study of Concurrent Male Partner Treatment for Bacterial Vaginosis.

Up to 50% of women receiving first-line antibiotics for bacterial vaginosis (BV) experience recurrence within 12 weeks. Evidence suggests that reinfection from an untreated regular sexual partner contributes to recurrence. We conducted a pilot study of 34 heterosexual couples to describe the impact of concurrent partner treatment on the composition of the genital microbiota over a 12-week period.

Gardnerella vaginalis Clade Distribution Is Associated With Behavioral Practices and Nugent Score in Women Who Have Sex With Women.

Background: Gardnerella vaginalis is detected in women with and without bacterial vaginosis (BV). Identification of 4 G. vaginalis clades raised the possibility that pathogenic and commensal clades exist.

Anal human papillomavirus infections in young unvaccinated men who have sex with men attending a sexual health clinic for HPV vaccination in Melbourne, Australia.

The Victorian Government introduced a time-limited quadrivalent human papillomavirus (HPV) vaccination catch-up program targeting gay and bisexual men who have sex with men (MSM) aged up to 26 years in 2017. As of 2017, men aged ≥20 years were not eligible for the school-based HPV vaccination program. This study examined the prevalence of anal HPV among 496 MSM aged 20-26 years before they received the first dose of the HPV vaccine at the Melbourne Sexual Health Centre, Australia.

Symptoms, Sites, and Significance of Mycoplasma genitalium in Men Who Have Sex with Men.

During 2016-2017, we tested asymptomatic men who have sex with men (MSM) in Melbourne, Australia, for Mycoplasma genitalium and macrolide resistance mutations in urine and anorectal swab specimens by using PCR. We compared M. genitalium detection rates for those asymptomatic men to those for MSM with proctitis and nongonococcal urethritis (NGU) over the same period.

Use of Pristinamycin for Macrolide-Resistant Mycoplasma genitalium Infection.

High levels of macrolide resistance and increasing fluoroquinolone resistance are found in Mycoplasma genitalium in many countries. We evaluated pristinamycin for macrolide-resistant M. genitalium in a sexual health center in Australia.

Combined oral and topical antimicrobial therapy for male partners of women with bacterial vaginosis: Acceptability, tolerability and impact on the genital microbiota of couples - A pilot study.

Objectives: Recurrence following recommended treatment for bacterial vaginosis is unacceptably high. While the pathogenesis of recurrence is not well understood, recent evidence indicates re-infection from sexual partners is likely to play a role. The aim of this study was to assess the acceptability and tolerability of topical and oral antimicrobial therapy in male partners of women with bacterial vaginosis (BV), and to investigate the impact of dual-partner treatment on the vaginal and penile microbiota.

Detection of human papillomavirus in urine among heterosexual men in relation to location of genital warts and circumcision status.

Objective: Human papillomavirus (HPV) surveillance is important to monitor the effectiveness of national HPV vaccination programmes. Positivity of HPV in urine in men varies with different sampling methods. We aimed to determine the positivity for detection of HPV-6/11 in urine samples among men in relation to the position of genital warts and circumcision status.

Microbial invasion of the amniotic cavity in midtrimester pregnancies using molecular microbiology.

Objective: The objective of the study was to determine the frequency of microbial invasion of the amniotic cavity in the midtrimester of pregnancy in patients undergoing amniocentesis for clinical indications.

Study Design: This was a prospective investigation of the amniotic fluid of 344 asymptomatic women recruited in midpregnancy for the presence of microbial DNA. Amniotic samples obtained at the time of amniocentesis for genetic testing on women between 15 and 22 weeks of gestation were tested specifically for the presence of Ureaplasma urealyticum, Ureaplasma parvum, Mycoplasma hominis, and Mycoplasma genitalium as well as for other bacteria and fungi using broad-range polymerase chain reaction only.

Quadrivalent vaccine-targeted human papillomavirus genotypes in heterosexual men after the Australian female human papillomavirus vaccination programme: a retrospective observational study.

Background: Australia introduced a national quadrivalent human papillomavirus (4vHPV) vaccination programme for girls and young women in April, 2007. The HPV genotypes targeted by the female vaccine could also affect the protection afforded to heterosexual men. We examined the prevalence of 4vHPV targeted vaccine genotypes and the nine-valent HPV (9vHPV)-targeted vaccines genotypes among sexually active, predominantly unvaccinated heterosexual men from 2004 to 2015.

Human papillomavirus in young women with Chlamydia trachomatis infection 7 years after the Australian human papillomavirus vaccination programme: a cross-sectional study.

Background: The national quadrivalent human papillomavirus (4vHPV) vaccination programme was launched in Australia in April, 2007. In this study, we aimed to explore the prevalence of vaccine-targeted human papillomavirus (HPV) types contained in the 4vHPV and nine-valent HPV (9vHPV) vaccines detected in young women diagnosed with chlamydia.

Methods: In this cross-sectional study, we identified specimens from women aged 25 years or younger who attended the Melbourne Sexual Health Centre (Melbourne, VIC, Australia) diagnosed with chlamydia.

Human papillomavirus type 6 and 11 genetic variants found in 71 oral and anogenital epithelial samples from Australia.

Genetic variation of 49 human papillomavirus (HPV) 6 and 22 HPV11 isolates from recurrent respiratory papillomatosis (RRP) (n = 17), genital warts (n = 43), anal cancer (n = 6) and cervical neoplasia cells (n = 5), was determined by sequencing the long control region (LCR) and the E6 and E7 genes. Comparative analysis of genetic variability was examined to determine whether different disease states resulting from HPV6 or HPV11 infection cluster into distinct variant groups. Sequence variation analysis of HPV6 revealed that isolates cluster into variants within previously described HPV6 lineages, with the majority (65%) clustering to HPV6 sublineage B1 across the three genomic regions examined.
