Research interest

Dr Patrick Harris is an Infectious Disease Physician and Medical Microbiologist, and is currently undertaking a PhD at The University of Queensland Centre for Clinical Research (UQCCR).    

Dr. Harris obtained a BSc in Psychology and Anthropology from Durham University, prior to acquiring his medical degree from University College London Medical School.  Following initial postgraduate training in the UK he worked as a clinical lecturer at the College of Medicine in Malawi, prior to completing specialist training in infectious diseases and microbiology in Australia.  For his final year of training he was a Senior Visiting Fellow in Infectious Disease at the National University Hospital in Singapore. He has published more than 26 peer-reviewed articles, most as first author, including recent publications in the Lancet, Lancet Infectious Diseases and Clinical Infectious Diseases. 

Research projects

Dr. Harris is currently undertaking a PhD with Professor David Paterson at UQCCR in the field of Gram-negative resistance, specifically undertaking clinical trials to help define optimal management of bloodstream infections caused by antibiotic-resistant pathogens. Current active projects include:

  1. 1. Randomised controlled trial of meropenem versus piperacillin-tazobactam for definitive treatment of bloodstream infections due to third generation cephalosporin non-susceptible Escherichia coli and Klebsiella spp. (MERINO trial) – an international multicentre study to compare carbapenem-sparing treatment options for ESBL and AmpC-producing species.  This will be the first large RCT to specifically address this question, using a protocol developed and endorsed by the Australasian Society for Infectious Diseases Clinical Research Network (ASID-CRN).

  2. 2. Pilot Randomised controlled trial of meropenem versus piperacillin-tazobactam for definitive treatment of bloodstream infections due to AmpC-producing Enterobacter, Citrobacter, Serratia, Providencia and Morganella (MERINO-2 trial).
  3. 3. The use of whole genome sequencing to characterise the resistome of Gram-negative pathogens causing bloodstream infections
