Understanding group A streptococcal pharyngitis and skin infections as causes of rheumatic fever: Protocol for a prospective disease incidence study

This study will identify the incidence of true Group A Streptococcal pharyngitis and serological responses to Group A Streptococcal GAS skin infections

Calculation of the age of the first infection for skin sores and scabies in five remote communities in northern Australia

The young age of the first infection with skin sores and scabies reflects the high disease burden in these communities

Development of an opsonophagocytic killing assay for Group A Streptococcus

Group A Streptococcus (GAS) or Streptococcus pyogenes is responsible for an estimated 500,000 deaths worldwide each year.

Epidemiology and risk factors for typhoid fever in Central Division, Fiji, 2014-2017: A case-control study

Poor sanitation facilities appear to be a major source of Salmonella Typhi in Fiji, with transmission by drinking contaminated surface water and consuming unwashed produce

Reach: to stop rheumatic heart disease

Reach works to promote the health of vulnerable populations by providing technical support to local, regional and global efforts to prevent and control rheumatic fever and rheumatic heart disease (RF/RHD).

Evaluation of a phased pneumococcal conjugate vaccine introduction in Mongolia using enhanced pneumonia surveillance and community carriage surveys

Streptococcus pneumoniae causes substantial morbidity and mortality among children. The introduction of pneumococcal conjugate vaccines (PCV) has the potential to dramatically reduce disease burden. As with any vaccine, it is important to evaluate PCV impact, to help guide decision-making and resource-allocation.

Describing skin health and disease in urban-living Aboriginal children: co-design, development and feasibility testing of the Koolungar Moorditj Healthy Skin pilot project

Indigenous 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 pharyngitis

Controlled 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 transporter

Described 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.
