We developed a chemical method to covalently functionalize cellulose nanofibers and cellulose paper with mannoside ligands displaying a strong affinity for the FimH adhesin from pathogenic E. coli strains. Mannose-grafted cellulose proved efficient to selectively bind FimH lectin and discriminate pathogenic E. coli strains from non-pathogenic ones. These modified papers are valuable tools for diagnosing infections promoted by E. coli, such as cystitis or inflammatory bowel diseases, and the concept may be applicable to other life-threatening pathogens.

Aims: This study aims to investigate the genomic profile of a multidrug-resistant Escherichia coli strain, 160-11H1, co-carrying an extended-spectrum β-lactamase (ESBL) and the plasmid-mediated mobile colistin resistance gene, mcr-5.
Methods And Results: The entire genome of the strain was sequenced using Illumina MiSeq and Oxford Nanopore platforms, and de novo assembly was performed using Unicycler. The genome size was 5 031,330 bp and comprised 5 140 coding sequences.

Enterotoxigenic (ETEC), a leading cause of diarrhea, is defined by heat-stable (ST) and/or heat-labile (LT) toxins and associated colonization factors (CFs). However, there is still a knowledge gap in understanding ETEC's evolution, particularly in endemic regions like Bangladesh. This study investigates the genomic attributes contributing to the rise of ETEC-associated diarrhea in Bangladesh during 2022-2023.

The rotation of the bacterial flagellum is powered by the MotAB stator complex, which converts ion flux into torque. Despite its central role in flagellar function, the evolutionary origin and structural diversity of this system remain poorly understood. Here, we present the first comprehensive phylogenetic and structural characterization of MotAB and its closest non-flagellar homologs.

Objectives: Urinary tract infections (UTIs) are among the most common infections worldwide, with being the predominant pathogen, particularly, in women. The rise of antimicrobial resistance, especially due to extended-spectrum β-lactamase-producing , has significantly limited treatment options, posing a serious public health concern. Rational antibiotic use and continuous monitoring of resistance patterns are essential to address this challenge.

Gastrointestinal eubiosis is essential for maintaining overall host wellbeing. Post-weaning diarrhea (PWD) is a common issue in pig development, arising from weaning stress, which disrupts the gut microbiota balance and increases susceptibility to infections. The primary bacterial pathogen linked to PWD is enterotoxigenic (ETEC).
