Infection & Immunity



Marc Bonten earned his MD (1991) and PhD (“the role of colonization of the upper intestinal tract in the pathogenesis of ventilator-associated pneumonia, 1994) at the Maastricht University Medical School, the Netherlands. He registered as internist in 2000, as infectious disease specialist in 2002 and as clinical microbiologist in 2008, all at the University Medical Center Utrecht, the Netherlands. From 2008 till March 2021 he was head of the Department of Medical Microbiology. Since 2003 he is head of the research group of Infectious Disease Epidemiology of the Julius Center of Health Sciences and Primary Care and professor of molecular epidemiology of infectious diseases. He has been a principal investigator in many large scale epidemiologic studies and investigator-initiated randomized trials of prevention and treatment of infectious diseases. His experience covers the full range of epidemiologic study designs including clinical trials, cohorts, case-control studies and mathematical modelling to study antibiotic resistance and infection prevention. Specific research interests include the epidemiology of antibiotic-resistant bacteria such as VRE, MRSA and MDR Enterobacteriaceae, selective decontamination in intensive care unit patients, prevention of ventilator-associated pneumonia, treatment of community-acquired pneumonia, and prevention and treatment of community-acquired pneumonia, including COVID-19.

He is scientific Director of the research theme "Tackling Antimicrobial Resistance" of the Netherlands Centre for One Health (NCOH; (2016-)
