Among the Enterobacteriaceae, Proteus vulgaris is exceptional in the inducible production of a 29-kDa β-lactamase (cefuroximase) with an unusually high activity towards the β-lactamase-stable oximino-cephalosporins (e.g. cefuroxime and cefotaxime).

Using clinical strains of Serratia marcescens with low and high resistance to extended-spectrum beta-lactam antibiotics, the relative contribution of chromosomal beta-lactamase and defective outer membrane porins to resistance was determined. Low-lev

The chromosomal ampC beta-lactamase in Citrobacter freundii and Enterobacter cloacae is inducible by beta-lactam antibiotics. When an inducible ampC gene is introduced on a plasmid into Escherichia coli together with its transcriptional regulator amp

SUMMARY Chemical mutagenesis of the AmpC -lactamase-hyperinducible Escherichia coli strain SN0301/pNu305 carrying the cloned ampC and ampR genes from Citrobacter freundii OS60 gave four independent mutants in which -lactamase was no longer inducible,

The mobilizable plasmid pMD101 (ampR, ampC) was constructed by inserting cloned ampC, the structural gene for the chromosomal AmpC beta-lactamase of Citrobacter freundii, and the closely linked ampR encoding the transcriptional regulator essential fo

It has been reasoned that bacterial β-lactamases must have a “normal” physiological function, apart from inactivating β-lactam antibiotics, probably connected to the metabolism of cell wall peptidoglycan (Abraham and Chain, 1940; Saz and Lowery

SUMMARY: A serum-resistant strain of Proteus mirabilis was used to determine whether changes in the composition of surface components could be detected following induction of progressive stages of cell form defectiveness by β-lactam antibiotics. The

The quantities of penicillin-binding proteins (PBPs), and sensitivity to extended-spectrum β-lactams, were measured in isogenic strains of Serratia marcescens with high (HR) and low (LR) resistance to extended-spectrum β-lactam antibiotics and with
