Safety, tolerability, and pharmacokinetics of a 2 g subcutaneous dose of ceftriaxone as an alternative to intravenous deliverySubcutaneous delivery of antibiotics is a practical alternative to intravenous administration. Ceftriaxone is commonly used for a variety of infections with limited data on the safety and pharmacokinetics of a 2 g subcutaneous dose. This was a prospective, self-controlled cross-over study in 20 stable inpatients receiving ceftriaxone for their infection. Following an intravenous dose, participants received a single dose of 2 g subcutaneous ceftriaxone, in 50 mL normal saline via gravity feed.

Impact of Host and Bacterial Metabolism on Antibiotic SusceptibilityAntimicrobial 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.

Trimodal skin health programme for childhood impetigo control in remote Western Australia (SToP): a cluster randomised, stepped-wedge trialSkin infections affect physical health and, through stigma, social-emotional health. When untreated, they can cause life-threatening conditions. We aimed to assess the effect of a holistic, co-designed, region-wide skin control programme on the prevalence of impetigo.

Antibiotic consumption for sore throat and the potential effect of a vaccine against group A Streptococcus: a systematic review and modelling studyAntibiotic consumption can lead to antimicrobial resistance and microbiome imbalance. We sought to estimate global antibiotic consumption for sore throat, and the potential reduction in consumption due to effective vaccination against group A Streptococcus.

Searching for Strep A in the clinical environment during a human challenge trial: a sub-study protocolStreptococcus pyogenes (also known as group A Streptococcus , Strep A) is an obligate human pathogen with significant global morbidity and mortality. Transmission is believed to occur primarily between individuals via respiratory droplets, but knowledge about other potential sources of transmission via aerosols or the environment is limited. Such knowledge is required to design optimal interventions to control transmission, particularly in endemic settings.

Development of methods to rapidly track pathogen and antibiotic resistance profiles from skin sores in Northern Australia (Hot North)Indigenous Australian children suffer the highest rates of impetigo (skin sores) in the world, which can result in serious immune complications including chronic kidney and possibly rheumatic heart disease.
