Standardization of Epidemiological Surveillance of Invasive Group A Streptococcal Infections

Invasive group A streptococcal (Strep A) infections occur when Streptococcus pyogenes, also known as beta-hemolytic group A Streptococcus, invades a normally sterile site in the body. This article provides guidelines for establishing surveillance for invasive Strep A infections. The primary objective of invasive Strep A surveillance is to monitor trends in rates of infection and determine the demographic and clinical characteristics of patients with laboratory-confirmed invasive Strep A infection, the age- and sex-specific incidence in the population of a defined geographic area, trends in risk factors, and the mortality rates and rates of nonfatal sequelae caused by invasive Strep A infections.

Group A Streptococcus M1T1 Intracellular Infection of Primary Tonsil Epithelial Cells Dampens Levels of Secreted IL-8 Through the Action of SpyCEP

Our results suggest that intracellular infection with the pathogenic GAS M1T1 clone induces a strong pro-inflammatory response in primary tonsil epithelial cells

Group A streptococcal pharyngitis: Immune responses involved in bacterial clearance and GAS-associated immunopathologies

Innate and adaptive host immune responses are fundamental for defense against streptococcal pharyngitis and are central to the clinical manifestation of disease.

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.
