Escherichia coli β-Lactamases: What Really Matters
Frontiers in Microbiology, 2016 Escherichia coli strains belonging to diverse pathotypes have increasingly been recognized as a major public health concern. The β-lactam antibiotics have been used successfully to treat infections caused by pathogenic E. coli.

Phenotypic detection of Metallo- and AmpC β-lactamases producing strains of P. aeruginosa in the state of Himachal Pradesh (India) [PDF]
Al Ameen Journal of Medical Sciences, 2015 Background: A prospective study was undertaken to detect metallo-β-lactamases (MBLs) and AmpC β-lactamases in Pseudomonas aeruginosa isolates recovered from patients at Indira Gandhi Medical College, Shimla (H.P).

Penetration of β-lactamase inhibitors into the periplasm of Gram-negative bacteria [PDF]
FEMS Microbiology Letters, 1999 The effectiveness of a beta-lactamase inhibitor/beta-lactam combination against Gram-negative pathogens depends on many interplaying factors, one of which is the penetration of the inhibitor across the outer membrane. In this work we have measured the relative penetrations of clavulanic acid, sulbactam, tazobactam and BRL 42715 into two strains of ...

Cefotaxime-hydrolysing activity of the β-lactamase ofKlebsiella oxytocaD488 could be related to a threonine residue at position 140 [PDF]
FEMS Microbiology Letters, 1991 The chromosomally encoded β-lactamase of Klebsiella oxytoca D483 strain, active against all third-generation cephalosporins but ceftazidime, was purified to homogeneity. The pure protein was digested by trypsin, Staphylococcus aureus V8 protease or proteinase Asp-N.

Detection of inducible β-lactamase by an agar dilution technique [PDF]
FEMS Microbiology Letters, 1985 An agar dilution technique for the detection of inducible β-lactamase-mediated resistance to the newer cephalosporins is described. Cefoxitin (16 μg/ml) was incorporated in agar plates together with cefamandole (8 μg/ml) or cefotaxime (8 μg/ml). The susceptibility of 35 strains of Enterobacter cloacae to these combinations was compared with their ...

Construction by polymerase chain reaction and intragenic DNA probes for three main types of transferable β-lactamases (TEM, SHV, CARB) [PDF]
FEMS Microbiology Letters, 1991 Intragenic DNA probes were synthesized by polymerase chain reaction using fragments of the genes of three major types of β-lactamases (TEM, SHV, CARB) as templates. The TEM probe hybridized with the genes encoding TEM-1, TEM-2 and six extended-spectrum related enzymes (TEM-3 to TEM-7, TEM-20) in colony hybridizations and Southern-blot analysis. The SHV

Indonesia Journal of Biomedical Science, 2019 Background: Escherichia coli belong to the family of Enterobacteriaceae that are responsible as one of the leading cause of nosocomial infections. The emergence of Carbapenem-resistant Enterobacteriaceae presents therapeutic challenges for clinicians on choosing the correct type of antibiotics to prescribe.
