Abstract:
This chapter presents the methodology to carry out infection of humanized plasminogen mice with Group A Streptococcus (GAS). This model of invasive disease has been widely used within the field to study the virulence of different GAS strains, host-pathogen interactions, the importance of particular virulence factors, and preclinical evaluation of novel treatments and vaccines. The model has shown to be highly reproducible and therefore represents an invaluable tool for GAS research.
