Increasing incidence of invasive group A streptococcal disease in Western Australia, particularly among Indigenous people

The incidence of invasive GAS disease in WA increased between 2000 and 2018, particularly among Indigenous Australians. Mandatory notification of invasive GAS disease would therefore be appropriate. The social determinants of differences in incidence should be addressed, and other relevant host, pathogen, and health system factors investigated.

Formative evaluation of a community-based approach to reduce the incidence of Strep A infections and acute rheumatic fever

We explore the acceptability of a novel, outreached-based approach to improve primary and primordial prevention of Strep A skin sores, sore throats and acute rheumatic fever in remote Aboriginal communities. A comprehensive prevention program delivered by trained Aboriginal Community Workers was evaluated using approximately fortnightly household surveys about health and housing and clinical records.

Revisiting the inoculum effect for Streptococcus pyogenes with a hollow fibre infection model

Severe, invasive Streptococcus pyogenes (Strep A) infections result in greater than 500,000 deaths annually. First line treatment for such infections is benzylpenicillin, often with the addition of clindamycin, but treatment failure can occur with this regimen. This failure has been partially attributed to the inoculum effect, which presents as reduced antibiotic susceptibility during high bacterial density and plateau-phase growth.

Urgent action needed to stop 500 preventable deaths

A new report predicts rheumatic heart disease (RHD) will lead to over 500 preventable deaths and cost the Australian health system $317 million by 2031 if no further action to tackle the disease is taken.

An economic case for a vaccine to prevent group A streptococcus skin infections

A vaccine that prevents GAS cellulitis and other skin infections, in addition to throat infections, would maximise its value and commercial viability

Development of an opsonophagocytic killing assay for group a streptococcus

This Group A Streptococcus OPKA assay has the potential to provide a robust and reproducible platform to accelerate GAS vaccine development.

Country-level and global burden of diseases caused by group A Streptococcus: protocol for a multicountry epidemiological study

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.

Antibiotic consumption for sore throat and the potential effect of a vaccine against group A Streptococcus: a systematic review and modelling study

Antibiotic 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.

Getting to grips with invasive group A streptococcal infection surveillance in Australia: are we experiencing an epidemic?
