Direct interaction between MreB and the RodA‐PBP2 complex organizes lateral cell wall synthesis in Escherichia coli

mLife, EarlyView.
Abstract The elongasome, or the Rod complex, orchestrates lateral peptidoglycan (PG) synthesis in many rod‐shaped bacteria. It consists of the actin‐like protein MreB, the PG synthase RodA‐PBP2 complex, as well as MreCD and RodZ. Although the loss or disruption of any elongasome component results in a loss of rod shape, previous studies found that a ...

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

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.

Reusing health records from farm animal practices at scale: A potential complementary method of surveillance

Veterinary Record, EarlyView.
Abstract Background Disease in primary care frequently represents a surveillance blind spot, particularly for diseases affecting farm animals. Methods Electronic health records (EHRs) were collected from four farm animal veterinary practices in Wales (February 2024‒January 2025) as part of a pilot study.

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 ...

Target Fidelity and Failure: Structure–Activity Relationship of High-Molecular-Mass Penicillin-Binding Proteins (HMM-PBPs) in Refractory Granulicatella adiacens Endocarditis

Antibiotics
Background/Objectives: Granulicatella adiacens infective endocarditis is conventionally managed with penicillin, ampicillin, or ceftriaxone in combination with gentamicin, although double beta-lactam regiments have been proposed a safer alternative to ...
