1. 11. Structural studies of enzymes regulating bacterial life style and cell wall biogenesis

   Författare :Ming Wei Chen; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Bacteria can adapt to different biotic and abiotic environments by changing their life style, switching between sessile or motile, free-living or community-bound, virulent or dormant states. Each bacterium also faces the challenges of maintaining a protective barrier while growing, replicating and responding to environmental changes. LÄS MER

3. 12. Regulation of biofilm formation in Salmonella typhimurium and Escherichia coli Nissle 1917

   Författare :Cláudia Monteiro; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Bacteria have the ability to grow in cell communities designated biofilms. This mode of growth is widespread and offers numerous advantages to the bacteria in terms of survival, persistence and propagation. Bacteria have developed different ways of building up a biofilm.

4. 13. Oxidoreductases and RNA degradosome controlling virulence-associated traits of Salmonella enterica serovar Typhimurium

   Författare :Naeem Anwar; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The oxidative stress response is a fundamental and primitive mode of innate immune defense in nearly all forms of life. The host oxidative stress response becomes truly important and effective especially against intracellular pathogens such as Salmonella. Pathogens have evolved diverse mechanisms to withstand the oxidative responses. LÄS MER

5. 14. Evolutionary trajectories of Klebsiella pneumoniae : From experimental biofilm evolution to a hospital outbreak

   Författare :Greta Zaborskytė; Linus Sandegren; Vaughn S. Cooper; Uppsala universitet; []
   Nyckelord :Klebsiella pneumoniae; evolution; experimental evolution; biofilms; infection; bacterial pathogens; Mikrobiologi; Microbiology;

   Sammanfattning : Bacterial evolution is closely intertwined with our lives. As their hosts, we shape how bacteria evolve by imposing numerous selective pressures during the time bacteria spend in our bodies. As a result, they adapt in various ways to colonize us or infect us better. LÄS MER

7. 15. Bacterial virulence and adaptation mediated by two-component system signalling

   Författare :Henrik Tomenius; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Virulence; atomic force microscopy; biofilm; adaptation; two-component system; signal transduction; gene regulation; phosphorylation; BarA; UvrY;

   Sammanfattning : One of the most fundamental ways of signal perception and propagation is mediated by the bacterial two-component system (TCS). These types of systems mediate bacterial adaptation that may cause disease in a host due to expression of virulence factors. LÄS MER
