Standardization of Epidemiological Surveillance of Group A Streptococcal ImpetigoImpetigo is a highly contagious bacterial infection of the superficial layer of skin. Impetigo is caused by group A Streptococcus (Strep A) and Staphylococcus aureus, alone or in combination, with the former predominating in many tropical climates. Strep A impetigo occurs mainly in early childhood, and the burden varies worldwide. It is an acute, self-limited disease, but many children experience frequent recurrences that make it a chronic illness in some endemic settings.

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.

Streptolysins are the primary inflammasome activators in macrophages during Streptococcus pyogenes infectionGroup A Streptococcus (GAS) is a Gram-positive bacterial pathogen that causes an array of infectious diseases in humans. Accumulating clinical evidence suggests that proinflammatory interleukin (IL)-1beta signaling plays an important role in GAS disease progression.

Defining Group A Streptococcus interaction with the tonsil epithelium to inform vaccine developmentA vaccine that prevents the initial attachment of Strep A to the tonsils would reduce the incidence of Strep throat and severe diseases that result.

Improved diagnosis, treatment and prevention of recurrent tonsillitisStrep A causes over 775 million infections each year world-wide, including over 615 million cases of tonsil infection (Strep throat).
