Polymersome‐Enabled Multimodal Delivery of Tobramycin and Doripenem for Targeted Eradication of Pseudomonas aeruginosa Biofilms in Chronic Rhinosinusitis

Small, EarlyView.
Schematic representation of diffusion‐based versus pH‐triggered drug release within a bacterial biofilm. In diffusion‐based systems, drug cargo is gradually released independent of local pH, resulting in rapid burst release and reduced sustained concentrations.

Characterization of YdgH: a mediator of beta-lactam susceptibility in Enterobacterales

Microbiology Spectrum
Beta-lactam antibiotics are often the treatment of choice for serious bacterial infections. In a previous screen for novel genetic mediators affecting beta-lactam susceptibility, we discovered that deletion of ydgH, a conserved gene of unknown function ...

Antimicrobial Residues in a Key Cerrado River: Distribution, Persistence, and Effects on Zebrafish Embryo‐Larval Development

Environmental Toxicology, EarlyView.
ABSTRACT The current study aimed to quantify the antimicrobials amoxicillin (AMX), cefazolin (CFZ), chloramphenicol (CHL), metronidazole (MTZ), and sulfamethoxazole (SX) in effluents and surface water of an important Cerrado river, calculate their half‐lives, and analyze their ecotoxicity following single and combined exposures.

ß-Lactam-ß-lactamase Inhibitor Combination against ESBL-Producing Enterobacteriaceae

Majallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2016
In the last decades, Extended-Spectrum-β-Lactamases (ESBLs) in gram negative bacilli have appeared as a significant mechanism of resistance to antibiotics. Although resistance to carbapenems is increasing among bacteria, they are still the treatment

Prevalence and Genomic Characterization of mcr‐Positive Enterobacteriaceae in Retail Meat in Thailand Following the Colistin Ban

Microbiology and Immunology, EarlyView.
ABSTRACT This study aimed to investigate the prevalence and characteristics of mcr‐positive Enterobacteriaceae in retail meat in Thailand following the national ban on prophylactic colistin use in food producing animals. A total of 152 meat samples (103 chicken and 49 pork) were collected from supermarkets and open markets between July and September ...

Resolved genomes of wastewater ESBL-producing Escherichia coli and metagenomic analysis of source wastewater samples

Microbiology Spectrum
Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli pose a serious threat to human health because of their resistance to the most commonly prescribed antibiotics: penicillins and cephalosporins.

Successful Application of the Mast Cell Activation Test in Immediate Hypersensitivity to Amoxicillin

Allergy, EarlyView.
This study included 28 amoxicillin‐allergic patients and 11 healthy exposed controls. Mast cells were differentiated from CD34+ progenitors over 8 weeks using cytokine cocktails. The mast cell activation test involved sensitization with patient or control sera and stimulation with free amoxicillin or G4/G5‐AXO dendrimers with successfully activated ...
