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.

Pneumococcal responses are similar in Papua New Guinean children aged 3-5 years vaccinated in infancy with pneumococcal polysaccharide vaccine with or without prior pneumococcal conjugate vaccine, or without pneumococcal vaccinationWe studied in a non-randomized follow-up trial the persistence of pneumococcal immunity in children, 3-5 years of age, in community controls of a similar age.

Otitis-prone children produce functional antibodies to pneumolysin and pneumococcal polysaccharidesThe production of functional antipneumococcal antibodies in otitisprone children demonstrates that they respond to the current pneumococcal conjugate vaccine (PCV)and are likely to respond to pneumolysin-based vaccines as effectively as healthy children.

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.

A collaborative yarn on qualitative health research with Aboriginal communitiesIn this paper, we seek to provide guidance for researchers who are new to undertaking research with Aboriginal and Torres Strait Islander communities

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.

Telehealth for Audiological ManagementThis chapter focuses on the management of those with hearing impairment, and how tele-audiological tools and approaches may assist to improve service delivery
Research
Recombinational exchange of M-fibril and T-pilus genes generates extensive cell surface diversity in the global group A Streptococcus populationAmong genes present in all group A streptococci (GAS), those encoding M-fibril and T-pilus proteins display the highest levels of sequence diversity, giving rise to the two primary serological typing schemes historically used to define strain. A new genotyping scheme for the pilin adhesin and backbone genes is developed and, when combined with emm typing, provides an account of the global GAS strain population.

Standardization of epidemiological surveillance of group A Streptococcal cellulitisCellulitis is an acute bacterial infection of the dermis and subcutaneous tissue usually found complicating a wound, ulcer, or dermatosis. This article provides guidelines for the surveillance of cellulitis.

Use of data linkage to investigate the aetiology of acute lower respiratory infection hospitalisations in childrenThe aim was to document the aetiology of acute lower respiratory infection (ALRI) hospitalisations in Western Australian children
Research
A pilot study to develop assessment tools for Group A Streptococcus surveillance studiesGroup A Streptococcus (GAS) causes pharyngitis (sore throat) and impetigo (skin sores) GAS pharyngitis triggers rheumatic fever (RF) with epidemiological evidence supporting that GAS impetigo may also trigger RF in Australian Aboriginal children. Understanding the concurrent burden of these superficial GAS infections is critical to RF prevention. This pilot study aimed to trial tools for concurrent surveillance of sore throats and skins sore for contemporary studies of RF pathogenesis including development of a sore throat checklist for Aboriginal families and pharynx photography.
