Drug-resistant Neisseria gonorrhoeae has become a global health concern that requires immediate attention. Due to increasing resistance to cephalosporins, pursuing novel alternatives for treating N. gonorrhoeae infections is paramount. Whilst new drug development is often cumbersome, reviving antiquated antibiotic agents for treatment of modern infections has become prevalent in clinical practice. Fosfomycin exhibits bactericidal activity through a unique mechanism of action, and a variety of organisms including N. gonorrhoeae are susceptible. In vitro studies have demonstrated that fosfomycin can retain activity against ceftriaxone-resistant N. gonorrhoeae; however, it remains unclear whether there is synergy between fosfomycin and other antibiotics. Clinical investigations evaluating fosfomycin for the treatment of N. gonorrhoeae infections are confounded by methodological limitations, none the less they do provide some perspective on its potential role in therapy. Future studies are needed to establish a safe, convenient and effective fosfomycin regimen for treating N. gonorrhoeae infections.

Rational selection of TbpB variants yields a bivalent vaccine with broad coverage against Neisseria gonorrhoeae.

Neisseria gonorrhoeae is an on-going public health problem due in part to the lack of success with efforts to develop an efficacious vaccine to prevent this sexually transmitted infection. The gonococcal transferrin binding protein B (TbpB) is an attractive candidate vaccine antigen. However, it exhibits high levels of antigenic variability, posing a significant obstacle in evoking a broadly protective immune response.

Background: Latin America-amidst its largest mass migration-has seen minimal progress in curbing new HIV infections. Transgender women (TW) in the region are disproportionately affected, but scant data examines HIV vulnerabilities alongside migration.
Methods: Between February-July 2022, 211 young TW ages 16-24 in Lima participated in a cross-sectional quantitative study accompanied by serological testing (HIV, syphilis, chlamydia, gonorrhea, hepatitis B).

Introduction: The US state of Florida has the third highest rate of HIV as well as high rates of sexually transmitted infections (STIs) indicating critical HIV and STI prevention needs remain unmet. To address gaps in the STI care continuum in people with HIV (PWH), evidence-based interventions were implemented across three Ryan White HIV/AIDS Program (RWHAP) funded clinics in Florida between August 2020-August 2021. Interventions included comprehensive sexual health history (SHH) taking using audio computer-assisted self-interview (ACASI) software, self-collected extragenital gonorrhea and chlamydia testing, and the introduction of a lesbian, gay, bisexual, transgender, and queer (LGBTQ+) welcoming environment.

Phylogenetic analyses are crucial for understanding microbial evolution and infectious disease transmission. Bacterial phylogenies are often inferred from SNP alignments, with SNPs as the fundamental signal within these data. SNP alignments can be reduced to a 'strict core' by removing those sites that do not have data present in every sample.

This article focuses on two key innovations in dermatology: post-exposure prophylaxis for sexually transmitted infections (STIs) and new therapeutic options for inflammatory skin diseases. New European and American guidelines for doxycycline post-exposure prophylaxis (Doxy PEP) aim to prevent STIs in men who have sex with men (MSM) and individuals on HIV pre-exposure prophylaxis (PrEP). Doxy PEP is effective against syphilis and chlamydia, but its efficacy is limited by growing gonorrhea resistance.
