Antibiotic resistance is recognised as a major global threat to public health by the World
Health Organization. Currently, several hundred thousand deaths yearly can be attributed to …

Incompatibility group IncHI plasmids are important vectors of antibiotic resistance in
Enterobacteriaceae. In this study, a scheme for typing IncHI into five separately clustering …

Salmonella enterica subsp. enterica bacteria are important foodborne pathogens with major
economic impact. Some isolates exhibit increased heat tolerance, a concern for food safety …

Protists kill their bacterial prey using toxic metals such as copper. Here we hypothesize that
the metalloid arsenic has a similar role. To test this hypothesis, we examined intracellular …

The continued agricultural exposure of bacteria to metals such as copper and zinc may
result in an increased copper tolerance through the food chain. The aim of this study was to …

Background and aim: There is a concern that biocides and metals can co-select for antibiotic
resistance. The aim of this thesis is to enhance our understanding of the roles of …
