1. Evolution of Antibiotic Resistance
Sammanfattning : The emergence of antimicrobial resistance is a major global threat to modern medicine. The rapid dissemination of resistant pathogens and the associated loss of efficacy of many important drugs needs to be met with the development of new antibiotics and alternative treatment options. LÄS MER
2. Bacterial Resistance to Antimicrobial Peptides : Rates, Mechanisms and Fitness Effects
Sammanfattning : The rapid emergence of bacterial resistance to antibiotics has necessitated the development of alternative treatment strategies. Antimicrobial peptides (AMPs) are important immune system components that kill microbes rapidly and have broad activity-spectra, making them promising leads for new pharmaceuticals. LÄS MER
3. 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.

4. Mechanisms and Dynamics of Mecillinam Resistance in Escherichia coli
Sammanfattning : The introduction of antibiotics in healthcare is one of the most important medical achievements with regard to reducing human morbidity and mortality. However, bacterial pathogens have acquired antibiotic resistance at an increasing rate, and due to a high prevalence of resistance to some antibiotics they can no longer be used therapeutically.

5. Biotic and abiotic drivers of life-history and demographic variation in boreal orchids
Sammanfattning : Environmental interactions, including both abiotic and biotic factors, are key drivers of life-history and population dynamics. Despite this, most population studies do not explicitly link variation in environmental factors and vital rates. LÄS MER
