Performance of a new in-house medium Carba MTL-broth for the rapid detection of carbapenemase-producing Enterobacteriaceae

Journal of Infection in Developing Countries, 2019
Introduction: The spread of carbapenemase-producing Enterobacteriaceae (CPE) represents a major public health issue. Methods allowing rapid detection of carbapenemases in developing countries are therefore urgently needed.

Evaluation of In Vitro Activity of Double-Carbapenem Combinations against KPC-2-, OXA-48- and NDM-Producing Escherichia coli and Klebsiella pneumoniae

Antibiotics, 2022
Double-carbapenem combinations have shown synergistic potential against carbapenemase-producing Enterobacterales, but data remain inconclusive. This study evaluated the activity of double-carbapenem combinations against 51 clinical KPC-2-, OXA-48-, NDM-1,

Predominance of OXA-48 Carbapenemase-Producing Enterobacterales in a Moroccan Hospital

International Journal of Microbiology, 2023
Objective. The emergence of carbapenemase-producing Enterobacterales (CPE) is a major concern that is increasingly reported worldwide. Our study aimed at investigating the resistance of CPE isolates in a Moroccan teaching hospital using phenotypic and genotypic methods. Methods.

Membrane‐Active Peptide Protects Against Inflammation by Targeting NLRP3 Activation at the Trans‐Golgi Network

Advanced Science, EarlyView.
The membrane‐active peptide Pep19‐2.5 reduces harmful inflammation by blocking activation of the NLRP3 inflammasome at trans‐Golgi network membranes. By targeting key membrane interactions, Pep19‐2.5 suppresses inflammatory IL‐1β production and alleviates allergic airway inflammation in mice, leading to reduced immune cell infiltration and improved ...

Review of In Vitro Efficacy of Ceftazidime-Avibactam, Meropenem-Vaborbactam and Imipenem-Relebactam in Carbapenemase Producing Klebsiella pneumoniae Isolates

Mediterranean Journal of Infection, Microbes and Antimicrobials, 2023
Introduction: To investigate the in vitro efficacy of three new antimicrobial agents [ceftazidime-avibactam (CAZ-AVI), meropenem-vaborbactam (V/R) and imipenem/cilastatin-relebactam] in isolates of carbapenemase-producing Klebsiella pneumoniae (CPKP ...

PEAR1 Promotes Glucose Metabolism Reprogramming in Sepsis‐Associated Acute Lung Injury via AARS1‐Mediated HIF‐1α Lactylation

Advanced Science, EarlyView.
This study revealed that a PEAR1/HIF‐1α/ glycolysis/lactate/H3K18la positive feedback loop in PMVECs that drives the development of S‐ALI. Mechanistically, PEAR1 mediates the binding of HIF‐1α to AARS1, leading to the lactylation of HIF‐1α, the primary lactylation site of which is K172.

Clinical outcomes of phenotype-guided treatment in group D carbapenemase-producing Enterobacterales bacteremia

Microbiology Spectrum
International guidance recommends ceftazidime-avibactam for OXA-48-type carbapenemase-producing Enterobacterales (OXA-48-CPE) infections. However, OXA-48-CPE lacking extended spectrum and AmpC β-lactamases may remain susceptible to third-generation ...

OXA-48-Mediated Ceftazidime-Avibactam Resistance Is Associated with Evolutionary Trade-Offs

mSphere, 2019
Infections due to carbapenemase-producing Gram-negative pathogens are associated with limited treatment options and consequently lead to increased mortality and morbidity.

Molecular epidemiology of OXA-48-producing Klebsiella pneumoniae in France [PDF]

Clinical Microbiology and Infection, 2014
We characterized 53 OXA-48-producing Klebsiella pneumoniae (OXA-48-Kp) isolated between 2011 and 2013 in 21 French hospitals. All the isolates were genotyped using MLST and PFGE and the population structure of the species was determined by a nucleotide-based analysis of the entire K. pneumoniae MLST database.

O‐GlcNAcylation Regulation of SNAP29‐Dependent Autophagy Activation Dictates Chemoresistance in Gastric Cancer

Advanced Science, EarlyView.
Model illustrating the proposed mechanism by which chemotherapy‐induced downregulation of OGT disrupts SNAP29 O‐GlcNAcylation, promoting STX17‐SNAP29‐VAMP8 SNARE complex assembly and protective autophagy, leading to chemoresistance, which in turn establishes a feedforward loop to perpetuate drug tolerance.
