The Mechanisms of Reactions of β-Lactam Antibiotics

, 1987
This chapter explains that penicillin was the first naturally occurring antibiotic to be characterized and used in clinical medicine. It can be seen as the progenitor of the β-lactam family of antibiotics, which are characterized by the possession of the

Conformational Snapshots of CydDC in a Native Lipid Bilayer Coupling Heme Transport to Antibiotic Resistance

Advanced Science, EarlyView.
Phylogenetic and biochemical analyses of the heme transporter CydDC reveal its functional conservation throughout bacterial evolution and demonstrate its unique asymmetric allosteric mechanism. Furthermore, impairment of CydDC function directly affects bacterial antibiotic resistance and likely compromises antibiotic efficacy through drug efflux.

A novel method to depurate β-lactam antibiotic residues by administration of a broad-spectrum β-lactamase enzyme in fish tissues

Fisheries and Aquatic Sciences, 2016
As a novel strategy to remove β-lactam antibiotic residues from fish tissues, utilization of β-lactamase, enzyme that normally degrades β-lactam structure-containing drugs, was explored.

Guidelines for Detecting the Foodborne Antibiotic‐Resistant Bacteria

AgriFood: Journal of Agricultural Products for Food, EarlyView.
ABSTRACT Foodborne antibiotic‐resistant bacteria threaten global public health and the economic. Standardized detection methods are crucial for effective prevention and control. Researchers encounter difficulties in choosing suitable techniques due to the variety of available approaches and the intricate nature of resistance mechanisms.

Interspecies Biofilm Dynamics Among Staphylococci: Inflammatory Contributions to Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Staphylococcus species are frequently isolated from the sinonasal niche of chronic rhinosinusitis (CRS) patients. While Staphylococcus aureus is often associated with recalcitrant CRS, Staphylococcus epidermidis and Staphylococcus lugdunensis are largely deemed commensal.

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Characterization of acquired β-lactamases in Pseudomonas aeruginosa and quantification of their contributions to resistance

Microbiology Spectrum
Pseudomonas aeruginosa is a highly problematic opportunistic pathogen that causes a range of different infections. Infections are commonly treated with β-lactam antibiotics, including cephalosporins, monobactams, penicillins, and carbapenems, with ...

Synthesis and enzyme-based evaluation of analogues L-tyrosine thiol carboxylic acid inhibitor of metallo-β-lactamase IMP-1

Journal of Enzyme Inhibition and Medicinal Chemistry, 2019
The emergence of drug-resistant pathogenic bacteria is occurring due to the global overuse and misuse of β-lactam antibiotics. Infections caused by some bacteria which secrete metallo-β-lactamases (enzymes that inactivate β-lactam antibiotics) are ...

Molecular targets of β-Lactam-based antimicrobials : Beyond the usual suspects : Beyond the usual suspects

, 2018
The common practice in antibacterial drug development has been to rapidly make an attempt to find ever-more stable and broad-spectrum variants for a particular antibiotic, once a drug resistance for that antibiotic is detected.
