   Sammanfattning : Bacteria have the ability to sense different environmental signals. When an environmental stress is detected, bacteria rapidly adjust their gene expression profile to be able to survive and thrive. LÄS MER

   Sammanfattning : Escherichia coli strains typical of UPEC (uropathogenic E. coli) and NBM (newborn meningitis) isolates carry chromosomally located PAIs (pathogenicity islands) that are absent in non-pathogenic E. coli strains. The PAIs include genes for virulence factors such as toxins and genes coding for specific adhesins and pili/fimbriae formation. LÄS MER
