Variants of Streptococcus pneumoniae Serotype 14 from Papua New Guinea with the Potential to Be Mistyped and Escape Vaccine-Induced ProtectionStreptococcus pneumoniae (the pneumococcus) is a human pathogen of global importance, classified into serotypes based on the type of capsular polysaccharide produced. Serotyping of pneumococci is essential for disease surveillance and vaccine impact measurement.

Major grant awarded to tackle antibiotic resistanceVital research aiming to improve the treatment of potentially deadly Group A Streptococcus (Strep A) has been awarded $820,000 in the latest round of National Health and Medicine Research Council’s Ideas Grants.

Modeling the potential health impact of prospective Strep A vaccinesThe World Health Organization published the preferred product characteristics for a Group A Streptococcus (Strep A) vaccine in 2018. Based on these parameters for the age of vaccination, vaccine efficacy, duration of protection from vaccine-derived immunity, and vaccination coverage, we developed a static cohort model to estimate the projected health impact of Strep A vaccination at the global, regional, and national levels and by country-income category.

The application of environmental health assessment strategies to detect Streptococcus pyogenes in Kimberley school classroomsChildren spend almost one-third of their waking hours at school. Streptococcus pyogenes (Strep A) is a common childhood bacterial infection that can progress to causing serious disease. We aimed to detect Strep A in classrooms by using environmental settle plates and swabbing of high-touch surfaces in two remote schools in the Kimberley, Western Australia.

Invasive Infections Caused by Lancefield Groups C/G and A Streptococcus, Western Australia, Australia, 2000–2018Epidemiologic data on invasive group C/G Streptococcus (iGCGS) infections are sparse internationally. Linked population-level hospital, pathology, and death data were used to describe the disease burden in Western Australia, Australia, during 2000-2018 compared with that of invasive group A Streptococcus (GAS, Streptococcus pyogenes) infections.

Isla's Invasive Strep A Story"I had never heard of invasive Streptococcus A disease before, and I was shocked to hear that it is actually three times more common than meningococcal disease and just as deadly yet there is no vaccine to protect against it."

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.

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 Acute Poststreptococcal GlomerulonephritisAcute poststreptococcal glomerulonephritis (APSGN) is an immune complex-induced glomerulonephritis that develops as a sequela of streptococcal infections. This article provides guidelines for the surveillance of APSGN due to group A Streptococcus (Strep A). The primary objectives of APSGN surveillance are to monitor trends in age- and sex-specific incidence, describe the demographic and clinical characteristics of patients with APSGN, document accompanying risk factors, then monitor trends in frequency of complications, illness duration, hospitalization rates, and mortality.
