Common Patterns and Unique Threats in Antimicrobial Resistance as Demonstrated by Global Gonococcal Surveillance.

The rapid emergence of antimicrobial-resistant strains of Neisseria gonorrhoeae threatens treatment options and control efforts. The Uniformed Services University Gonococcal Reference Laboratory and Repository of the Global Emerging Infections Surveillance Program receives isolates from several geographically distinct regions worldwide. We analyzed 962 isolates collected during 2014-2022 for genomic and phenotypic antimicrobial resistance.

isolates resistant to extended spectrum cephalosporins and macrolides isolated from symptomatic men in western Kenya.

Background: We characterized the antimicrobial resistance (AMR) profiles of (NG) isolated from symptomatic men at a sexually transmitted infection clinic in Kisumu, Kenya.

Methods: Two urethral swabs were obtained from symptomatic men between 2020 and 2022, one for Gram's stain and the other inoculated directly onto modified Thayer-Martin media containing 1% VCNT and 1% IsoVitaleX enrichment. Culture results were confirmed by colony morphology, Gram's stain and oxidase test.

Isolation and Growth Kinetics of Bogoria Virus from Phlebotomine Sandflies Sampled in Baringo, Kenya.

Phleboviruses are an emerging threat to public health. Recent surveillance efforts in Kenya have unveiled novel phleboviruses. Despite these efforts, there remain knowledge gaps.

Comparative analysis of peripheral whole blood transcriptome from asymptomatic carriers reveals upregulation of subsets of surface proteins implicated in phenotypic plasticity.

The molecular mechanism underlying persistence in the asymptomatic phase of infection remains largely unknown. However, large-scale shifts in the parasites' gene expression during asymptomatic infections may enhance phenotypic plasticity, maximizing their fitness and leading to the persistence of the asymptomatic infections. To uncover these mechanisms, we aimed to identify parasite genetic factors implicated in asymptomatic infections through whole transcriptome analysis.

In Vitro Pre-Clinical Evaluation of a Gonococcal Trivalent Candidate Vaccine Identified by Transcriptomics.

Gonorrhea, a sexually transmitted disease caused by , poses a significant global public health threat. Infection in women can be asymptomatic and may result in severe reproductive complications. Escalating antibiotic resistance underscores the need for an effective vaccine.

We report the sequencing of two viruses, Phasi Charoen-like phasivirus (PCLV) and Fako virus (FAKV), which were detected in a pool of from Kenya. Analysis showed a high similarity of PCLV to publicly available PCLV genomes from Kenya. FAKV showed a high genetic divergence from publicly available FAKV genomes.

Therapeutic response to artemisinin combination therapies among individuals with Plasmodium falciparum single infection vs mixed Plasmodium species infections: a retrospective posthoc analysis in Kisumu County, western Kenya.

Objectives: This study examined the treatment response of mixed vs single-species Plasmodium falciparum infections to artemisinin-based combination therapies (ACTs).

Methods: A total of 1211 blood samples collected on days 0, 7, 14, 21, 28, 35, and 42 from 173 individuals enrolled in two randomized ACT efficacy studies were tested for malaria using 18s ribosomal RNA-based real-time polymerase chain reaction. All recurrent parasitemia were characterized for Plasmodium species composition and time to reinfection during 42-day follow-up compared across ACTs.

Estimating Chlamydia and Gonorrhea Burden Among US Army Soldiers From Military Health System Data: Mind the Gap.

Background: Reporting systems are commonly used for chlamydia and gonorrhea surveillance and community burden assessments. Estimates are conservative given high proportions of asymptomatic cases and underreporting. The military's unified health system, which includes laboratory and medical encounter data, could offer insight into surveillance gaps and improve burden analyses.

Sexually Transmitted Infections in the U.S. Military: A Sexual Health Paradigm to Address Risk Behaviors, Unintended Pregnancy, Alcohol Use, and Sexual Trauma.

To address the ongoing epidemic of sexually transmitted infections (STIs) in the United States, the National Academies of Sciences, Engineering, and Medicine (National Academies) conducted a consensus study on STI control and prevention in the United States to provide recommendations to the Centers for Disease Control and Prevention and the National Association of County and City Health Officials. The culminating report identified military personnel as one of the priority groups that require special consideration given the high prevalence of STIs and their associated behaviors (e.g.

Identifying Nontraditional Epidemic Disease Risk Factors Associated with Major Health Events from World Health Organization and World Bank Open Data.

Health events emerge from host, community, environment, and pathogen factors-forecasting epidemics is a complex task. We describe an exploratory analysis to identify economic risk factors that could aid epidemic risk assessment. A line list was constructed using the World Health Organization Disease Outbreak News (2016-2018) and economic indicators from the World Bank.

The serogroup B meningococcal outer membrane vesicle-based vaccine 4CMenB induces cross-species protection against Neisseria gonorrhoeae.

There is a pressing need for a gonorrhea vaccine due to the high disease burden associated with gonococcal infections globally and the rapid evolution of antibiotic resistance in Neisseria gonorrhoeae (Ng). Current gonorrhea vaccine research is in the stages of antigen discovery and the identification of protective immune responses, and no vaccine has been tested in clinical trials in over 30 years. Recently, however, it was reported in a retrospective case-control study that vaccination of humans with a serogroup B Neisseria meningitidis (Nm) outer membrane vesicle (OMV) vaccine (MeNZB) was associated with reduced rates of gonorrhea.

Biomedical Response to Neisseria gonorrhoeae and Other Sexually Transmitted Infections in the US Military.

Introduction: Sexually transmitted infections (STIs) continue to plague militaries and defense forces. While the historical recognition of the impact of STIs on operations is evident, contemporary surveillance and research activities are limited. As Neisseria gonorrhoeae and other sexually transmitted pathogens become increasingly resistant to antibiotics, the role of the Department of Defense (DoD) in disease surveillance and clinical research is essential to military Force Health Protection.

Risk factors associated with gonorrhea and chlamydia transmission in selected health facilities in Ghana.

Background: Understanding the underlying epidemiology that shapes Neisseria gonorrhoeae (GC), and Chlamydia trachomatis (CT) infections can contribute to data driven policies directed towards curbing the proliferation of these pathogens in Ghana. Information on the symptoms and risk factors for STIs will help to identify high-risk individuals which will in turn inform STI syndromic management and tailor the use of public health resources.

Methods: Participants were from 4 military clinics and 1 civilian STI clinic in Ghana and eligible if they had symptoms suggestive of STI.

Extragenital chlamydia infection among active-duty women in the United States Navy.

Background: Pharyngeal and anorectal reservoirs of gonorrhea (GC) and chlamydia (CT) are increasingly recognized among heterosexual women. While a number of studies performed at sexually transmitted disease (STD) clinics have found a high prevalence of extragenital GC/CT infection, such screening is typically not offered during routine primary care visits for women. We sought to define the prevalence of and factors associated with extragenital GC/CT among women in the U.
