A complex network of regulatory systems ensures a coordinated and effective response to
different types of stress that can act on a bacterium. Bacterial stress response generates …

In Escherichia coli infection, the implications of fluoroquinolone (FQ) and extended-spectrum
cephalosporin plus cephamycin (AmpC) resistance for phylogenetic origin and virulence …

Escherichia coli strains frequently are isolated from skin and soft tissue infections (SSTI);
