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.

Sodium deoxycholate synergistically enhances the antimicrobial activity of β-lactam antibiotics againstβ-lactamase-producing Staphylococcus aureus [PDF]

, 2012
Background β-lactamase-producing Staphylococcus aureus synthesizes a β-lactamase which decomposes the β-lactam ring, and consequently almost all β-lactam antibiotics are inactivated by the enzyme. The appearance of β-lactamase-producing bacterial strains

Antibiotic Remodeling of the Gut Microbiota Impairs Host Resistance to Secondary Infection

iMetaMed, EarlyView.
Gut microbial dynamics induced by four antibiotics, revealed distinct taxonomic and functional shifts. Vancomycin‐perturbed bacteriomes were proven to promote pathogen resistance to antibiotic treatment. Metronidazole‐treated mice showed pronounced Salmonella translocation to hepatic tissue, and altered Enterococcus avium populations modulated host ...
