Altered phenotypes associated with ampD mutations in Enterobacter cloacae.

Antimicrobial agents and chemotherapy - 1 Feb 1991

Korfmann G, Sanders C C, Moland E S

Abstract excerpt

A study was done to determine the genetic locus responsible for altered expression of AmpC beta-lactamase in Enterobacter cloacae 1194E and several mutants derived from E. cloacae 029. These phenotypes were defined by units of enzyme activity found in sonic extracts of cells before and after induction with cefoxitin and included (units uninduced/units induced) the wild-type (7/219), high-level constitutive...
