A Single‐Nucleotide Substitution Generates a de Novo Promoter That Activates a Latent Metabolic Bypass in Escherichia coli

Molecular Microbiology, Volume 126, Issue 3, Page 244-251, September 2026.
A chromosomal mutation allows bypass of deletion of the Escherichia coli fabH gene. The bypass results from creation of a new promoter that drives increased madA transcription, resulting in increased synthesis of acetyl‐acyl carrier protein by decarboxylation of malonyl‐acyl carrier protein.

The Synergy Between a Silver‐Ruthenium Antimicrobial and Aminoglycosides Is Based on Severe Macromolecular Damage

Molecular Microbiology, Volume 126, Issue 3, Page 267-282, September 2026.
AGXX enhances aminoglycoside activity against multidrug‐resistant pathogens such as uropathogenic Escherichia coli by increasing reactive oxygen species, causing protein aggregation and DNA damage. This effect is reduced by oxygen limitation or antioxidants. Polyphosphate protects cells from oxidative damage.

Global Genomic Epidemiology of Escherichia coli (ExPEC) ST38 Lineage Revealed a Virulome Associated with Human Infections

Microorganisms, 2022
Background: Most of the extraintestinal human infections worldwide are caused by specific extraintestinal pathogenic Escherichia coli (ExPEC) lineages, which also present a zoonotic character. One of these lineages belongs to ST38, a high-risk globally disseminated ExPEC. To get insights on the aspects of the global ST38 epidemiology and evolution as a

Using Ongoing Wildlife Surveillance Programs to Monitor Antibiotic Resistant Bacteria in the Environment

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Screening of ESBL‐, pAmpC‐ and carbapenemase‐producing Escherichia coli among Swedish wildlife demonstrated a low occurrence of antibiotic resistance in wild animals. Only two ESBL/pAmpC‐producers were detected in red foxes originating from highly populated areas.

Occurrence, diversity and antimicrobial resistance of Enterobacterales isolated from artisanal ‘coalho’ cheese produced in north‐eastern Brazil

International Journal of Dairy Technology, Volume 79, Issue 3, July‐September 2026.
Artisanal ‘coalho’ cheese from north‐eastern Brazil harbours diverse Enterobacterales, including strains with antimicrobial resistance, virulence‐associated genes and biofilm‐forming ability. Although resistance levels were generally low, the findings highlight the need for improved hygienic practices and continuous microbiological surveillance within ...

Detection of Extended-spectrum β-lactamase-producing Escherichia coli isolates by isothermal amplification and association of their virulence genes and phylogroups with extraintestinal infection

Scientific Reports, 2023
Extraintestinal pathogenic Escherichia coli (ExPEC) producing extended-spectrum β-lactamases (ESBL) cause serious human infections due to their virulence and multidrug resistance (MDR) profiles.

Earthworms With Low Dose n‐MoS2 Improve Soybean Yield and Quality by Reconfiguring Rhizosphere Chemistry and Strengthening Nitrogen Fixation

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Nano‐enabled fertilizers can enhance biological nitrogen fixation (BNF) and yield in legumes; yet, their interactions with earthworms remain poorly understood. Herein, we performed a 120‐day greenhouse experiment applying low‐dose n‐MoS2 at 10 mg kg−1 with earthworms to evaluate interactive effects on soybean yield and underlying mechanisms ...

Sugar Alcohols as Crosslinking Delay Additives for Fracturing Fluids

Gels
The development of thermally stable fracturing fluids is essential for the effective stimulation of deep and low-permeability reservoirs. The stabilizing additives used in these fluids typically fall into three categories: crosslinking delay molecules ...
