This investigation aims to establish a prospective surveillance of Gram-Negative Bloodstream Infections in tertiary children’s hospitals throughout Australia.


Gram-negative organisms cause almost one half of all bloodstream infections (BSI) in children with comorbidities and are associated with significant morbidity and mortality. Understanding the clinical and molecular epidemiology of Gram-negative BSI (GNBSI) and multi-drug GNBSI in children is necessary to facilitate the development and evaluation of the most effective antimicrobial treatment strategies in children.


This surveillance will augment data collected by the Australian Group on Antimicrobial Resistance (AGAR) Gram-negative Sepsis Outcome Program and will help explain transmission dynamics of both susceptible and resistant invasive Gram-negative organisms in Australian children.
