Efficacy of β-lactam/β-lactamase inhibitor combination is linked to WhiB4-mediated changes in redox physiology of Mycobacterium tuberculosis

eLife, 2017
Mycobacterium tuberculosis (Mtb) expresses a broad-spectrum β-lactamase (BlaC) that mediates resistance to one of the highly effective antibacterials, β-lactams.

Potent monoclonal antibodies against multidrug‐resistant hypervirulent Klebsiella pneumoniae

Interdisciplinary Medicine, EarlyView.
A novel immunization strategy using a low‐virulence, multidrug‐resistant strain yields synergistic monoclonal antibodies against hypervirulent Klebsiella pneumoniae. These antibodies provide cross‐serotype protection through a dual‐mechanism of pathogen clearance and immunomodulation, offering a promising non‐antibiotic therapeutic for resistant ...

Duplex Recombinase Polymerase Amplification‐Lateral Flow Assay for Rapid Visual Detection of Critical Antibiotic Resistance Genes in Escherichia coli and Klebsiella pneumoniae From Positive Blood Cultures

Journal of Clinical Laboratory Analysis, EarlyView.
This study developed a pair of duplex RPA‐LFA assays for the simultaneous detection of critical resistance genes, blaCTX‐M/mcr‐1 and blaoxa‐48‐like/blaNDM, from hemoculture samples. Under optimized conditions, duplex RPA was performed at 37°C–38°C for 25 min, followed by LFA for 10–15 min.

In Vivo Resistance to Ceftolozane/Tazobactam in Pseudomonas aeruginosa Arising by AmpC- and Non-AmpC-Mediated Pathways

Case Reports in Infectious Diseases, 2018
Two pairs of ceftolozane/tazobactam susceptible/resistant P. aeruginosa were isolated from 2 patients after exposure to β-lactams. The genetic basis of ceftolozane/tazobactam resistance was evaluated, and β-lactam-resistant mechanisms were assessed by ...

On‐site pilot‐scale advanced oxidation pretreatment of hospital wastewater: assessment of pharmaceuticals, pathogens, antibiotic resistance genes and acute ecotoxicity

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Hospital premises generate wastewater containing a wide spectrum of contaminants, such as pharmaceutically active compounds (PhACs), antibiotic resistance genes (ARGs) and pathogenic microorganisms, whilst plenty of them are classified under the antibiotic resistant bacteria (ΑRΒ) category.

Detecting Antibiotic Resistance in Strains of Selected Gram‐Negative Bacterial Species Using Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
Raman spectroscopy successfully identified antibiotic‐resistant Gram‐negative strains. Resistant strains of four bacterial species were discriminated from sensitive ones with 99.1% accuracy using PLS regression. The method allows for rapid, label‐free detection of antibiotic resistance.

Nanjing Consensus II on Washed Microbiota Transplantation: Statements From the CHINAGUT Conference

Microbiota Medicine Research, EarlyView.
ABSTRACT The new method of fecal microbiota transplantation, based on automatic facilities and washing processes, was coined as washed microbiota transplantation (WMT). The first recommendations on WMT were released as Nanjing Consensus report by the fecal microbiota transplantation (FMT)‐standardization Study Group in 2019.

Synthesis and Bioactivity of Thiazolethioacetamides as Potential Metallo-β-Lactamase Inhibitors

Antibiotics, 2020
Metallo-β-lactamase (MβLs) mediated antibiotic resistance seriously threatens the treatment of bacterial diseases. Recently, we found that thioacetamides can be a potential MβL inhibitor skeleton. In order to improve the information of the
