Overproduction of Chromosomal <i>ampC</i> β-Lactamase Gene Maintains Resistance to Cefazolin in Escherichia coli Isolates Open
This study is the first to demonstrate that mutations in the chromosomal- amp C attenuator region are responsible for the emergence of cefazolin resistance in Escherichia coli strains. The resistance was maintained even after culturing E. …
