The Strep A Translation team aim to understand the epidemiology of Strep A infections in Australia and the world. Alongside this, they explore the implementation of endgame recommendations, health economics and new horizons.
Licensed recombinant protein respiratory syncytial virus (RSV) vaccines can prevent substantial morbidity in older adults. However, revaccination to prevent waning protection may be suboptimal, prompting the exploration of candidates for heterologous boosting. In this clinical trial of RSV vaccine-naive older adults, we evaluated SCB-1019T, a novel unadjuvanted bivalent RSV prefusion F (preF) protein vaccine stabilized via Trimer-Tag technology, in comparison to the licensed AS01E-adjuvanted RSV vaccine Arexvy.
Gram-negative bacterial infections remain a major cause of morbidity and mortality in children and neonates globally, compounded by the rise of antimicrobial resistance. Barriers to paediatric antibiotic licencing lead to reduced availability of potentially effective agents for treatment. For children and neonates in the Oceania region, specific challenges remain including a paucity of surveillance data on local rates of antimicrobial resistance, and lack of availability of newer, more costly agents.
Controlling the syphilis epidemic in Australia is a public health priority. Regular intramuscular (IM) injections of benzathine penicillin G (BPG) are the current standard of care for late latent syphilis in Australia; however, repeated IM BPG injections are painful, and treatment completion rates are low. Early-phase clinical trials have demonstrated the tolerability and safety of high-dose subcutaneous infusions of BPG (SCIP), where the total treatment dose can be delivered at a single visit. Here we describe the experiences and preferences of attendees of Western Australian sexual health clinics in the Perth metropolitan region who have syphilis and were treated with SCIP.
Japan recently experienced a record surge in streptococcal toxic shock syndrome. Our environmental surveillance study reveals that Streptococcus pyogenes persists seasonally, peaking in autumn and winter in rural Japan. The dominant emm1 M1UK sublineage and csrS mutations heighten virulence, highlighting the urgent need for targeted surveillance and interventions.
Differential exposure and effect of malaria results from blends of biophysical, geospatial, and social determinants of health (SDoH). Likewise, effective policies and programmatic interventions against malaria must consider the complex interaction of social and spatial factors, while comprehensive health promotion approaches must simultaneously tackle SDoH and the ecological dimensions that drive malaria.
Group A Streptococcus (Strep A) causes a wide spectrum of diseases, ranging from pharyngitis and impetigo to severe invasive infections and immune-mediated conditions such as acute rheumatic fever, rheumatic heart disease and acute post-streptococcal glomerulonephritis. Contemporary data on the global burden of Strep A diseases are lacking.
Asymptomatic carriage of Streptococcus pyogenes (Strep A) may contribute to transmission, yet its role remains poorly understood and evidence on optimal detection methods is limited. While self-collected throat swabs are used in infectious disease surveillance, their value for identifying asymptomatic Strep A carriage in adults is uncertain. This pilot prospective cohort study, conducted at a Perth medical research institute between August and October 2024, assessed feasibility and acceptability of self-collection, with sensitivity as a secondary objective.
Antimicrobial resistance (AMR) is a global healthcare emergency, directly causing 1.3 million deaths per year and predicted to increase dramatically over the coming decades. Understanding the molecular mechanisms underpinning antibiotic resistance is central to approaches for AMR surveillance and diagnosis in a clinical laboratory.
Obesity was a risk factor for severe COVID-19 in children during early outbreaks of ancestral SARS-CoV-2 and the Delta variant. However, the relationship between obesity and COVID-19 severity during the Omicron wave remains unclear.
