Mutations in ampD cause hyperproduction of AmpC and CmcB β-lactamases and high resistance to β-lactam antibiotics in Chromobacterium violaceum

Microbiology Spectrum
Bacterial resistance to β-lactam antibiotics mediated by β-lactamase enzymes is widespread worldwide. Chromobacterium violaceum, an environmental Gram-negative bacterial pathogen, is intrinsically resistant to some β-lactam antibiotics.

A systematic scoping review of metrics utilized to measure antibiotic consumption in hospital settings

British Journal of Clinical Pharmacology, EarlyView.
Abstract Antimicrobial stewardship (AMS) programs were introduced to promote the judicious use of antimicrobials and to combat antimicrobial resistance. Quantifying antibiotic consumption is an important part of AMS initiatives to achieve these objectives.

Population pharmacokinetic modelling of amoxicillin in human breast milk—A contribution from the ConcePTION project

British Journal of Clinical Pharmacology, EarlyView.
Aims Amoxicillin, a widely used β‐lactam antibiotic, requires improved pharmacokinetic characterization during breastfeeding. This study used a population pharmacokinetic (PopPK) approach to model amoxicillin concentrations in breast milk, identify variability sources and estimate infant exposure, applying worst‐case scenarios.

Pd(II)‐Catalyzed Strategies for the β‐Arylation of α‐Amino Acids: An Overview

Chemistry – A European Journal, EarlyView.
The graphical abstract summarizes the review “Pd(II)‐Catalyzed Strategies for the β‐Arylation of α‐Amino Acids: An Overview”, highlighting representative Pd(II)‐catalyzed methods for the β‐arylation of α‐amino acids. Key mechanistic features, substrate diversity, and synthetic relevance of these transformations are showcased. Abstract Metal‐catalyzed C─

β-Lactam Antibiotics Renaissance

Antibiotics, 2014
Since the 1940s β-lactam antibiotics have been used to treat bacterial infections. However, emergence and dissemination of β-lactam resistance has reached the point where many marketed β-lactams no longer are clinically effective.

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

The effect of combined sewer overflows on the abundance of antibiotic resistance genes and bacteria in the James River [PDF]

, 2017
Antibiotic resistance is a major threat to human health. Clinical situations are the main focus for antibiotic resistance research, but understanding the spread of resistance in the environment is also vital.

Transfer of antibiotic resistance in Staphylococcus aureus [PDF]

, 2017
Staphylococcus aureus is a serious human pathogen with remarkable adaptive powers. Antibiotic-resistant clones rapidly emerge mainly by acquisition of antibiotic-resistance genes from other S. aureus strains or even from other genera.
