Show moreThis thesis is divided into three parts. The first part of this thesis describes the epidemiology of infections with Clostridioides difficile, meticillin-resistant Staphylococcus aureus and colistin-resistant Enterobacterales. An important treatment strategy for recurrent C. difficile infections is restoring the disturbed gut microbiota by faecal microbiota transplantation (FMT). The second part discusses the risk of transmission of pathogenic and/or multidrug-resistant bacteria via FMT and procedures to prevent this. Apart from recurrent C. difficile infections, several new potential indications of FMT are being explored. In the third part of this thesis, FMT is explored as a potential new treatment strategy for several neurological disorders, with a main focus on Parkinson’s disease. Show less

Show moreThe aim of this thesis was to stimulate rational and effective use of antimicrobials, by addressing the first two cornerstones: (1) refining stewardship of existing antimicrobials and (2) re-introducing old antibiotics within the framework of antimicrobial stewardship. The overall aim is to contribute to antimicrobial stewardship and to explore the value of the re-introduction of old antibiotics that are currently scarcely used. The basic step is the in vitro relationship expressed as minimal inhibitory concentration (MIC) for a given bacteria for a given antibiotic. The next step is the in vivo situation. This thesis concentrates on the in vivo situation. Show less
