6. Computational discovery of antibiotic resistance genes and their horizontal transfer
Sammanfattning : Antibiotic resistance is increasing among clinical infections and represents one of the most serious threats to public health. Pathogens often become resistant by acquiring mobile antibiotic resistance genes (ARGs) via horizontal gene transfer (HGT). LÄS MER
7. Mechanisms and Dynamics of Carbapenem Resistance in Escherichia coli
Sammanfattning : The emergence of extended spectrum β-lactamase (ESBL) producing Enterobacteriaceae worldwide has led to an increased use of carbapenems and may drive the development of carbapenem resistance. Existing mechanisms are mainly due to acquired carbapenemases or the combination of ESBL-production and reduced outer membrane permeability. LÄS MER
8. Studies on Translation Initiation and Termination in Escherichia coli
Sammanfattning : Translation initiation factor 1 (IF1) has been shown to be an RNA chaperone. In order to find functional interactions that IF1 may have with rRNA, we have isolated second-site suppressors of a cold-sensitive IF1 mutant. LÄS MER
9. Analysis of large-scale metagenomic data
Sammanfattning : The topic of this thesis is the analysis of large data sets of DNA sequence data produced from modern high-throughput DNA sequencing machines. Using such machines to sequence the genetic content of a microbial community produces a metagenome. This thesis comprises three research papers, all connected to the study of large metagenomic data sets. LÄS MER
10. Resistance to Fluoroquinolones in Escherichia coli: Prevention, Genetics and Fitness Costs
Sammanfattning : Antibiotic-resistant bacteria are increasingly a major healthcare problem but very few new classes of antibiotics have been discovered or launched in recent decades. Approaches to dealing with the problem include learning how bacteria evolve to resistance and improving dosing regimens with current antibiotics so as to reduce the selection of resistant bacteria.
