Trials 2022 Jun 16;23(1):495. Epub 2022 Jun 16.

Department of Global Health, University of Washington, Box 359931, 325 Ninth Ave, WA, 98104, Seattle, USA.

Background: Women in Africa face disproportionate risk of human immunodeficiency virus (HIV) acquisition, accounting for more than half of new infections in Africa and similarly face a disproportionate burden of sexually transmitted infections (STIs). Very high STI prevalence is being observed globally, especially among people taking pre-exposure prophylaxis (PrEP) for HIV prevention. Doxycycline post-exposure prophylaxis (dPEP) has been proposed as an STI prevention strategy to reduce chlamydia, syphilis, and possibly gonorrhea, and trials are ongoing among cisgender men who have sex with men (MSM) and transgender women who are taking PrEP in high-income settings.

Mycoplasma genitalium screening in a specialized French unit: A retrospective study.

Ann Dermatol Venereol 2022 Jun 8. Epub 2022 Jun 8.

Department of Dermatology, Genital Diseases and STIs unit, Saint-Louis Hospital, 1, avenue Claude Vellefaux, 75010 Paris, France.

Objective: Mycoplasma genitalium (MG) infection accounts for 10-35% of non-gonococcal non-chlamydial (NGNC) urethritis. However, given that most people infected with MG do not develop symptoms and that antimicrobial resistance is increasing worldwide, there is no evidence of any benefits of screening asymptomatic individuals. We conducted this study to describe MG screening practices and outcomes at a French Sexually Transmitted Infections (STI) center in which MG testing was performed selectively and multiplex assays were not carried out [i.

WHO Collaborating Centre for Gonorrhoea and Other Sexually Transmitted Infections, Department of Laboratory Medicine, Faculty of Medicine and Health, Örebro University, Örebro, Sweden; Institute for Global Health, University College London, London, UK. Electronic address:

Background: Genomic surveillance using quality-assured whole-genome sequencing (WGS) together with epidemiological and antimicrobial resistance (AMR) data is essential to characterise the circulating Neisseria gonorrhoeae lineages and their association to patient groups (defined by demographic and epidemiological factors). In 2013, the European gonococcal population was characterised genomically for the first time. We describe the European gonococcal population in 2018 and identify emerging or vanishing lineages associated with AMR and epidemiological characteristics of patients, to elucidate recent changes in AMR and gonorrhoea epidemiology in Europe.

Molecular Identification of Cervical Microbes in HIV-Negative and HIV-Positive Women in an African Setting Using a Customized Bacterial Vaginosis Microbial DNA Quantitative PCR (qPCR) Array.

Microbiol Spectr 2022 Jun 1:e0222921. Epub 2022 Jun 1.

Division of Medical Virology, Department of Pathology, Faculty of Health Sciences, University of Cape Towngrid.7836.a, Cape Town, South Africa.

Bacterial vaginosis (BV) is a common polymicrobial vaginal disorder that is associated with sexually transmitted infections (STIs), including HIV. Several studies have utilized broad-range 16S rRNA gene PCR assays with sequence analysis to characterize cervicovaginal bacterial communities of women with healthy and diseased conditions. With the high burden of BV and STIs among African women, there is a need for targeted PCR assays that can rapidly determine the true epidemiological profile of key cervical microbes, including BV-associated bacteria, and a need to explore the utility of such assays for microbiological diagnosis of BV.

Mobility of extracellular DNA within gonococcal colonies.

Biofilm 2022 Dec 20;4:100078. Epub 2022 May 20.

Institute for Biological Physics, University of Cologne, Zülpicherstr. 47a, 50647, Köln, Germany.

Transformation enables bacteria to acquire genetic information from extracellular DNA (eDNA). Close proximity between bacteria in colonies and biofilms may inhibit escape of eDNA from the colony but it also hinders its diffusion between donor and recipient. In this study, we investigate the mobility of DNA within colonies formed by , and relate it to transformation efficiency. Read More
