Targeting Class A and C Serine \u3b2-Lactamases with a Broad-Spectrum Boronic Acid Derivative [PDF]

, 2014
Production of \u3b2-lactamases (BLs) is the most widespread resistance mechanism adopted by bacteria to fight \u3b2-lactam antibiotics. The substrate spectrum of BLs has become increasingly broad, posing a serious health problem. Thus, there is an urgent

In vitro activity of cefepime/zidebactam (WCK 5222) against Gram-negative bacteria [PDF]

, 2017
Background: Diazabicyclooctanes (DBOs) inhibit class A, class C and some class D β-lactamases. A few also bind PBP2, conferring direct antibacterial activity and a β-lactamase-independent ‘enhancer' effect, potentiating β-lactams targeting PBP3.

Phenotypic detection of AmpC β-lactamases, extended-spectrum- β-lactamases and metallo-β-lactamases in Enterobacteriaceae using a resazurin microtitre assay with inhibitor-based methods. [PDF]

Dissemination of antibiotic resistance in Enterobacteriaceae mediated by AmpC, ESBL and MBL β-lactamases is clinically significant. A simple, relatively quick method for the detection of these resistance phenotypes would greatly improve chemotherapeutic ...

Phenotypic Characterization and Antibiotic Resistance Patterns of Extended-Spectrum β-Lactamase- and AmpC β-Lactamase-Producing Gram-Negative Bacteria in a Referral Hospital, Saudi Arabia

Canadian Journal of Infectious Diseases and Medical Microbiology, 2019
Background. Emergence of pathogenic bacteria carrying β-lactamase-resistant determinants has become a major health problem in the hospital setting. The study aimed to determine antibiotic-resistant patterns and frequency of extended-spectrum β-lactamase-

Impact of Prophylactic Cefepime on Surgical Site Infection and Severe Morbidity in Patients Who Underwent Pancreaticoduodenectomy With Preoperative Biliary Drainage

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Although prophylactic broad‐spectrum antibiotics can reduce postoperative complications after pancreaticoduodenectomy (PD), the optimal regimen remains uncertain. This study evaluated the impact of prophylactic cefepime (CFPM) on surgical site infection (SSI) and severe morbidity after PD with preoperative biliary drainage.

Multidrug resistant, extended spectrum β-lactamase (ESBL)-producing Escherichia coli isolated from a dairy farm [PDF]

, 2016
Escherichia coli strains were isolated from a single dairy farm as a sentinel organism for the persistence of antibiotic resistance genes in the farm environment. Selective microbiological media were used to isolate 126 E.

Prevalence of β-lactamase production and multi-drug resistance among uropathogenic Escherichia coli isolates at a tertiary care hospital of North-western India

Asian Journal of Medical Sciences, 2021
Background: E.coli is the most common organism causing UTI. Inappropriate and widespread use of broad-spectrum antibiotics has resulted in development of multi-drug resistance and β-lactamases producing strains.

Diversity, transfer potential, and transcriptional activity of virus‐carried antibiotic resistance genes in global estuaries

iMetaOmics, EarlyView.
Estuaries are vital hotspots for antibiotic resistance genes (ARGs) due to substantial antibiotic pollution. Although viruses have been proposed as key reservoirs and important disseminators of ARGs in environments, their contribution to the estuarine antibiotic resistome remains largely unknown.

Potential of high-dose cefepime/tazobactam against multi-resistant Gram-negative pathogens [PDF]

, 2017
Background: Early β-lactamase inhibitors were combined with established penicillins, but different combinations may be more appropriate to counter current β-lactamase threats, with development facilitated by the US Generating Antibiotic Incentives Now ...
