Microbial Genomics & Microbiomics
Microbial Genomics & Microbiomics
The Microbial Genomic & Microbiomics research group - under leadership of prof. dr. Rob Willems (who succeeded prof. dr. Marc Bonten as group leader as of 2017) - has three major research lines: (1) Molecular & Cellular Host-Microbiota Interactions, (2) Microbiomics and (3) Genomics & Genome-based Epidemiology of Antimicrobial Resistance.

Molecular & Cellular Host-Microbiota Interactions
PI: Dr. Marcel de Zoete, associate professor
The intestinal microbiota plays a key role in health and disease, often through direct bacterial interactions with the host intestinal (immune) cells or by released bacterial metabolites. Our main goal is to understand molecular mechanisms that underly pathogenic host-microbiota interactions. An important focus are ‘pathogenic’ commensals called pathobionts, which often live within the intestinal mucus layer in close proximity or attached to intestinal epithelial cells. The interactions of these pathobionts with the host epithelium and immune system are mostly unclear but believed to dramatically impact on various disease, including inflammatory bowel disease, colorectal cancer and metabolic syndrome. By unraveling the molecular mechanisms behind pathological host-microbiota interactions, we aim to pave the road for the development of novel therapeutic approaches.

Microbiomics
PI: Dr. Fernanda Paganelli, assistant professor
We use next generation sequencing techniques to determine the role of the microbiome in relation to disease, such as chronic infectious and immunological diseases as well as transmission of antibiotic resistant genes in communities and hospitals. Furthermore, we use colon organoids model to study the host response to specific bacterial communities.
Genomics & Genome-based Epidemiology of Antimicrobial Resistance
PI: Dr. Anita Schürch, assistant professor
Dissemination of physiologically important traits encoded on plasmids, integrons, transposons, and bacteriophages are highly dynamic because these mobile genetic elements (MGE) transmit with ease. The most prominent example is the spread of antimicrobial resistance (AMR) genes through different hosts and environments. We develop novel computational methods to reconstruct plasmids and other MGEs and to map their dissemination. Several genomics software tools have been developed and made made publicly available by this research group, including Gplas and mlplasmids.

Prof. dr. Rob Willems studied biology at the Free University in Amsterdam and acquired his PhD from the Utrecht University in 1993 on “Genetic and functional studies on Bordetella pertussis fimbriae”. After postdoc positions at the Faculty of Veterinary Medicine, Utrecht University and at the Department of Infectious Diseases of the University Hospital, Leiden he became research scientist and section head at the National Institute for Public Health and the Environment (RIVM) in 1996. In 2003 he moved from the RIVM to the University Medical Center Utrecht where he became assistant professor. In 2008 he was appointed associate professor and since December 1st 2016, he is full professor of Population Genetics of Antibiotic Resistance at the department of Medical Microbiology of the University Medical Center Utrecht.
