1. The Physiological Cost of Antibiotic Resistance
Abstract : Becoming antibiotic resistant is often associated with fitness costs for the resistant bacteria. This is seen as a loss of competitiveness against the antibiotic-sensitive wild-type in an antibiotic-free environment. READ MORE

2. Genetics and Growth Regulation in Salmonella enterica
Abstract : Most free-living bacteria will encounter different environments and it is therefore critical to be able to rapidly adjust to new growth conditions in order to be competitively successful. Responding to changes requires efficient gene regulation in terms of transcription, RNA stability, translation and post-translational modifications. READ MORE

3. Too close for comfort : The role of Contact-Dependent growth Inhibition (CDI) in interbacterial competition and cooperation
Abstract : Contact-Dependent growth inhibition (CDI) was discovered in 2005 in the E. coli isolate EC93. Since then our knowledge of CDI systems and their impact on bacterial communities have increased exponentially. READ MORE

4. Growth in Aging Colonies : The Importance of Being Different
Abstract : The accumulation of rifampicin resistant (RifR) mutants in aging bacterial colonies has previously been attributed to stress-induced mutagenesis. Mutations giving rise to RifR are located in the rpoB gene, coding for the β subunit of RNA polymerase, RpoB. READ MORE

5. Dynamics of the Bacterial Genome : Rates and Mechanisms of Mutation
Abstract : Bacterial chromosomes are highly dynamic, continuously changing with respect to gene content and size via a number of processes, including deletions that result in gene loss. How deletions form and at what rates has been the focus of this thesis. In paper II we investigated how chromosomal location affects chromosomal deletion rates in S. READ MORE
