Marie Bashir Institute for Infectious Diseases and Biosecurity

Marie Bashir Institute for Infectious Diseases and Biosecurity


The University of Sydney’s Marie Bashir Institute for Infectious Diseases and Biosecurity is a national, Asia-Pacific and global leader in the field of infectious diseases and biosecurity. It brings together leading research and expertise across a wide range of disciplines to increase capacity to detect and respond to infectious disease outbreaks in humans and animals.



Research highlights

  • The Centre for Research Excellence into Critical Infections, led by Professor Jon Iredell and based at Westmead Hospital, has developed new rapid diagnostic tests which allow antibiotic treatment to be provided quickly to people in severe sepsis, dramatically reducing mortality of those with critical infections.
  • Our researchers informed clinical practice guidelines relating to the use of intravenous immunoglobulin in suspected or proven neonatal sepsis.
  • Research by Professor Warwick Britton and his team at the affiliated Centenary Institute include programs to decrease the incidence of tuberculosis that not only help discriminate between active infectious and latent non-infectious tuberculosis, but also help monitor the response to antibiotic therapy.
