Streptococcus pyogenes or Group A streptococcus (GAS) is a gram positive bacterium that can cause a wide variety of diseases ranging from pharyngitis and tonsillitis to severe invasive diseases, such as necrotizing fasciitis (“flesh eating disease”) and streptococcal toxic shock syndrome. Streptococcal sequela, which includes glomerulonephritis and acute rheumatic fever, are often complications of streptococcal infection and remain a significant problem in NZ. My Present research into the pili (very thin, hair-like structures protruding from the surface of the bacterial cell) of GAS investigates the potential use of the pilus as a target for vaccine development. My results have shown that pili proteins are highly immunogenic and can elicit strong antibody responses in mice and rabbits. My work also focuses on the development of bioluminescent GAS strains for high-throughput monitoring of immune responses, as well as development of mouse infection models for vaccination studies.
