Integrating ecological feedbacks across scales and levels of organization

Ecography, Volume 2026, Issue 5, May 2026.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Characterization of Virulence Genetic Profile and Potential Effect of Nanoparticles against Multidrug-Resistant Uropathogenic E. coli at Menuofia University Hospitals

Journal of Pure and Applied Microbiology
One of the most significant pathogens involved in urinary tract infections is Uropathogenic E. coli (UPEC). In addition to assessing biofilm production and the effect of gold and silver nanoparticles on the isolated strains’ ability to form biofilms, the

Common and specific genomic sequences of avian and human extraintestinal pathogenic Escherichia coli as determined by genomic subtractive hybridization

BMC Microbiology, 2007
Background Suppression subtractive hybridization (SSH) strategy was used with extraintestinal pathogenic Escherichia coli (EXPEC) that cause avian colibacillosis (avian pathogenic E. coli or APEC) and human urinary tract infections (uropathogenic E. coli

Metalloids: Semi as Metals yet Full of Antimicrobial Potential

ChemMedChem, Volume 21, Issue 7, 14 April 2026.
Metalloids such as boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te) bridge metals and non‐metals, displaying unique chemical versatility. Recent research highlights their diverse antimicrobial and therapeutic potentials, from natural products to synthetic organic and organometallic molcules, underscoring renewed ...

Spatially‐nested topologies stabilize meta‐ecosystems via cross‐scale source‐sink dynamics

Ecology, Volume 107, Issue 4, April 2026.
Abstract Ecosystems are open to spatial flows of nonliving resources and dispersing organisms that can interact to drive their dynamics and functions. Empirical evidence shows resource flows and dispersal commonly have contrasting properties: resource flows connect nearby ecosystems of different types, while dispersal connects relatively distant ...

Generation of Nano‐Antibodies Targeting the SNMP1 Membrane Receptor of Spodoptera littoralis Using Extracellular Vesicles

Journal of Extracellular Biology, Volume 5, Issue 4, April 2026.
Extracellular vesicles (EVs) represent an excellent platform for the expression of recombinant membrane proteins and their use in llama immunization to generate nano‐antibodies (Nabs). In this study, we present a novel strategy, termed the multi‐layer approach, for EV immobilization in biopanning and ELISA applications.

Imported Retail Beef and Chicken Meat Products Serve as Reservoirs for Emerging Antibiotic‐Resistant Pathotypes of Escherichia coli in Pristine Areas Free From Agricultural Activity

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Retail meat–derived E. coli frequently harbored multidrug‑resistance phenotypes, diverse virulence determinants, and plasmid‑encoded resistance genes with high conjugative potential. Results indicate meat and poultry as underrecognized reservoirs facilitating dissemination of antimicrobial resistance and pathogenic lineages, with imported products ...

Investigation of Recombinantly Produced Endolysins Reveals a Modular Enzyme Shared by Several Enterobacteria Phages to Exhibit Broad‐Range Lytic Activity Against Different Orders of Gammaproteobacteria

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
The recombinant endolysin El1 derived from Enterobacteria bacteriophages showed potent bactericidal activity against Gram‐negative bacteria when applied exogenously, even in the absence of membrane‐permeabilizing agents, such as ethylenediaminetetraacetic acid (EDTA).

Efficacy and Safety of Second‐Line Advanced Therapy After Vedolizumab in Ulcerative Colitis: A Multicenter Cohort Study From the GETAID

United European Gastroenterology Journal, Volume 14, Issue 3, April 2026.
ABSTRACT Background and Aims Vedolizumab has become the preferred first‐line advanced therapy in ulcerative colitis (UC). However, the optimal second‐line treatment following vedolizumab failure remains unclear. We aimed to evaluate the effectiveness and safety of second‐line therapies after first‐line vedolizumab.

Functional heterogeneity of the UpaH autotransporter protein from uropathogenic Escherichia coli [PDF]

, 2012
Uropathogenic Escherichia coli (UPEC) are responsible for the majority of urinary tract infections(UTI). To cause UTI, UPEC must adhere to epithelial cells of the urinary tract and overcome the shear flow forces of urine.
