Status of research and development of vaccines for Streptococcus pyogenes

Vaccines against Streptococcus pyogenes are considered as impeded vaccines because of a number of crucial barriers to development

Modes of transmission and attack rates of group A Streptococcal infection: a protocol for a systematic review and meta-analysis

Summarising the current knowledge of Strep A transmission to humans will address gaps in the evidence and inform prevention and control strategies. The objective of this study is to evaluate the modes of transmission and attack rates of group A streptococcal infection in human populations.

Starting the SToP trial: Lessons from a collaborative recruitment approach

Recruitment in research can be challenging in Australian Aboriginal contexts. We aimed to evaluate the SToP (See, Treat, Prevent skin infections) trial recruitment approach for Aboriginal families to identify barriers and facilitators and understand the utility of the visual resource used.

Evaluating the role of asymptomatic throat carriage of Streptococcus pyogenes in impetigo transmission in remote Aboriginal communities in Northern Territory, Australia: a retrospective genomic analysis

Streptococcus pyogenes, or group A Streptococcus (GAS), infections contribute to a high burden of disease in Aboriginal Australians, causing skin infections and immune sequelae such as rheumatic heart disease. Controlling skin infections in these populations has proven difficult, with transmission dynamics being poorly understood. We aimed to identify the relative contributions of impetigo and asymptomatic throat carriage to GAS transmission.

Standardization of Epidemiological Surveillance of Group A Streptococcal Impetigo

Impetigo 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.

Delivery at 37 weeks' gestation is associated with a higher risk for child behavioural problems

We suggest that 37 weeks' gestation may not be the optimal cutoff for defining perinatal risk as it applies to behavioural development.

Re-analysis of the association between perinatal androgens and postnatal head circumference growth

This paper is a correction of an earlier report that identified a link between exposure to high levels of testosterone during pregnancy and reduced head...

Free testosterone levels in umbilical cord blood predict infant head circumference in girls

Fetal androgens influence fetal growth as well as postnatal neurocognitive ability.
