Defining target penicillin concentrations for subsequent studies of a reformulated long-acting benzathine penicillin prototypeAims: To determine the minimum inhibitory concentrations of penicillin G against a representative collection of Strep A strains; and to evaluate the impact of penicillin G concentration and size of bacterial inoculum on the prophylactic effect for Strep A strains

Describing skin health and disease in urban-living Aboriginal children: co-design, development and feasibility testing of the Koolungar Moorditj Healthy Skin pilot projectIndigenous children in colonised nations experience high rates of health disparities linked to historical trauma resulting from displacement and dispossession, as well as ongoing systemic racism. Skin infections and their complications are one such health inequity, with the highest global burden described in remote-living Australian Aboriginal and/or Torres Strait Islander (hereafter respectfully referred to as Aboriginal) children. Yet despite increasing urbanisation, little is known about the skin infection burden for urban-living Aboriginal children.

Transmission potential of Streptococcus pyogenes during a controlled human infection trial of pharyngitisControlled human infection (CHI) models can provide insights into transmission of pathogens such as Streptococcus pyogenes (Strep A). As part of the Controlled Human Infection with Penicillin for Streptococcus pyogenes (CHIPS) trial, we explored the potential for transmission among participants deliberately infected with the Strep A emm75 strain.

Host-dependent resistance of Group A Streptococcus to sulfamethoxazole mediated by a horizontally-acquired reduced folate transporterDescribed antimicrobial resistance mechanisms enable bacteria to avoid the direct effects of antibiotics and can be monitored by in vitro susceptibility testing and genetic methods. Here we describe a mechanism of sulfamethoxazole resistance that requires a host metabolite for activity.

Penicillin G concentrations required for prophylaxis against Group A Streptococcus infection evaluated using a hollow fibre model and mathematical modellingAcute rheumatic fever (ARF), an autoimmune reaction to Group A Streptococcus (Streptococcus pyogenes; Strep A) infection, can cause rheumatic heart disease (RHD). New formulations of long-acting penicillins are being developed for secondary prophylaxis of ARF and RHD.

Standardization of Epidemiological Surveillance of Group A Streptococcal PharyngitisPharyngitis, more commonly known as sore throat, is caused by viral and/or bacterial infections. Group A Streptococcus (Strep A) is the most common bacterial cause of pharyngitis. Strep A pharyngitis is an acute, self-limiting disease but if undertreated can lead to suppurative complications, nonsuppurative poststreptococcal immune-mediated diseases, and toxigenic presentations.

Whole-cell pertussis vaccine in early infancy for the prevention of allergyThis is a protocol for a Cochrane Review (intervention). The objectives were to assess the efficacy and safety of whole‐cell pertussis (wP) vaccinations in comparison to acellular pertussis (aP) vaccinations in early infancy for the prevention of atopic diseases in children.

Designing a paediatric teleotology pilot in the UK: Outcomes from a scoping review of the literature, with insights from the Ear Portal pilot service in Perth, Western AustraliaTo inform the design of a United Kingdom (UK) paediatric teleotology pilot by analysing global teleotology initiatives and drawing on insights from a successful paediatric teleotology pilot service in Perth, Western Australia (Ear Portal).

Goroka Otitis Media Study: Prevalence and associated risk factors of otitis media in children attending urban clinics in Goroka, Eastern Highlands Province of Papua New GuineaOtitis media (OM, middle ear infections) and the consequent hearing loss are major concerns for Aboriginal people and OM can seriously impact on children’s learning potential which in turn will impact on life as an adult.
