BACKGROUND: Detection of Ureaplasma, Mycoplasma and Candida spp. in the vagina during pregnancy has previously been associated with preterm birth (PTB). However, the prevalence of these microorganisms and the associated obstetric risks (likely to be population-specific) have not been determined in Australian women; furthermore, in the case of Ureaplasma spp., very few studies have attempted characterisation at the species level and none have examined genotype/serovar status to further refine risk assessment...

BACKGROUND: Most sexually transmitted infection (STI) management efforts focus on the syndromic approach to diagnose and treat patients. However, most women with STIs have been shown to be entirely asymptomatic, or if symptoms exist, are often missed when either clinical or conventional bacteriologic diagnostic tools are employed. METHODS: We assessed the performance of a multiplex real time PCR assay to describe other potential pathogens that could be missed by conventional bacteriological techniques in 200 women attending a routine STI clinic in Kumasi, Ghana...

Isolation of Mycoplasma genitalium from clinical specimens remains difficult and few strains are available for antimicrobial susceptibility testing. We describe the antimicrobial susceptibility of M. genitalium strains grown in Vero cell culture with first- and second- line antibiotics, using a modified cell-culture-based method. Macrolide- and -fluoroquinolone resistance determinants were detected by sequencing of the 23S and parC genes, respectively. Seven strains were examined, including three new, genetically distinct M...

PURPOSE: Pelvic inflammatory disease (PID) disproportionately affects adolescent and young adult (AYA) women and can negatively influence reproductive health trajectories. Few randomized controlled trials (RCTs) have focused on strategies to improve outpatient adherence or to reduce reproductive morbidity in this population. This paper describes the research methods and preliminary effectiveness of recruitment, retention, and intervention strategies employed in a novel RCT designed to test a technology-enhanced community-health nursing (TECH-N) intervention among urban AYA with PID...

Mycoplasma genitalium is a cause of 10-35% of non-chlamydial non-gonococcal urethritis in men and in women, and is associated with cervicitis and pelvic inflammatory disease (PID). Transmission of M. genitalium occurs through direct mucosal contact. In women, symptoms include vaginal discharge, dysuria or symptoms of PID - abdominal pain and dyspareunia. In men, urethritis, dysuria and discharge predominates. Asymptomatic infections are frequent. In this review, we present the evidence base for the recommendations in the 2016 European guideline on M...

A non-syndromic approach to treatment of people with non-gonococcal urethritis (NGU) requires identification of pathogens and understanding of the role of those pathogens in causing disease. The most commonly detected and isolated micro-organisms in the male urethral tract are bacteria belonging to the family of Mycoplasmataceae, in particular Ureaplasma urealyticum and Ureaplasma parvum To better understand the role of these Ureaplasma species in NGU, we have performed a prospective analysis of male patients voluntarily attending a drop in STI clinic in Oslo...

The numbers of rectal sexually transmitted infections are on the rise especially among men who have sex with men. Males from men who have sex with men population are encouraged to send a rectal swab to the laboratory for sexually transmitted infection screening at their visit to the Genitourinary Medicine Clinic. In healthy asymptomatic males, the range of pathogens tested is limited therefore other pathogens may be left untreated allowing infections to persist among sexual partners. Molecular techniques have revolutionarised sexually transmitted infection testing enabling the detection of previously difficult-to-culture pathogens in extra-genital sites and have increased the evidence base for their clinical significance...

Mycoplasma genitalium infection contributes to 10-35% of non-chlamydial non-gonococcal urethritis in men. In women, M. genitalium is associated with cervicitis and pelvic inflammatory disease (PID). Transmission of M. genitalium occurs through direct mucosal contact. Asymptomatic infections are frequent. In women, symptoms include vaginal discharge, dysuria or symptoms of PID - abdominal pain and dyspareunia. In men, urethritis, dysuria and discharge predominates. Besides symptoms, indication for laboratory test is a high-risk sexual behaviour...

OBJECTIVES: Mycoplasma genitalium is an important cause of STI in men and women. Worldwide evidence suggests a reduction in efficacy of azithromycin treatment due to the prevalence of macrolide resistant M. genitalium. The aim of this study was to describe the prevalence of macrolide resistance in patients with a positive test for M. genitalium within our setting. METHODS: Two STI clinics in Stockholm offered tests for M. genitalium as part of a routine care pathway...

Men were enrolled in a study to assess the performance and acceptability of self-collected penile meatal swabs as compared to clinician-collected urethral swabs for sexually transmitted infections (STIs). We expected penile-meatal swabs to perform favorably to urethral swabs for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Trichomonas vaginalis (TV), and Mycoplasma genitalium (MG) detection by nucleic acid amplification assays (NAATs). Of 203 swab pairs tested; for CT, penile-meatal swab sensitivity was 96...

Macrolide-resistant strains of Mycoplasma genitalium are an increasing problem throughout the world, and the implementation of a rapid and sensitive assay for mutation detection to guide treatment is needed. Macrolide-resistant strains have been shown to contain base substitutions in positions 2058 and 2059 (Escherichia coli numbering) in region V of the 23S rRNA gene. In this study, we present a SimpleProbe PCR followed by melting curve analysis to differentiate between macrolide-resistant mutants and wild types...

Among 323 specimens from male patients with symptoms of non-gonococcal urethritis, Mycoplasma genitalium was detected in 19 samples by real-time PCR. Mutations of 23S rRNA gene associated with macrolide resistance were confirmed in 10 strains. Amino acid changes at positions 81 and 83 of ParC protein were demonstrated indicating quinolone resistance of two strains.

The link between high-risk human Papillomavirus (HR-HPV) and other sexually transmitted diseases (STDs) in the risk of developing cervical cancer still unclear. Thus, in this report we investigated the rates of co-infections between HPV and other important non-HPV STDs in different cervical findings using a multiplex polymerase chain reaction (M-PCR) to simultaneously detect Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis, HSV-1 and -2, and Treponema pallidum. A total of 838 women aged 18 to 68 years were screened using Papanicolaou smears for cervical abnormalities, HPV and non-HPV STDs using PCR and M-PCR methods...
