When the AmpC is expressed in higher level (derepressed) it will predictably confer resistance to all 3rd generation cephlosporins except cefepime.
[14] The Cefoxitin-BA method cannot differentiate between plasmid-mediated AmpC, iAmpC or derepressed AmpC enzymes.
Previously, our laboratory showed fimB expression was derepressed in an ompR mutant UPEC strain in a low pH environment [28] and OmpR was critical for UPEC survival in the murine urinary tract [66].
Totipotent subpopulation in mouse ESCs and naive-like subpopulation in human ESCs are derepressed in ERV expression, concomitantly with its expression in early embryos.
