yqhG Contributes to Oxidative Stress Resistance and Virulence of Uropathogenic Escherichia coli and Identification of Other Genes Altering Expression of Type 1 Fimbriae

Frontiers in Cellular and Infection Microbiology, 2019
Urinary tract infections (UTIs) are common bacterial infections and the vast majority of UTIs are caused by extraintestinal pathogenic Escherichia coli (ExPEC) strains referred to as uropathogenic E. coli (UPEC).

Bacterial Extracellular Vesicles: New Hype or Hope to Explain Reproductive Host–Microbiota Interactions

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
ABSTRACT Rapid advances in microbiome research are transforming our understanding of human health and disease, with growing focus on the female reproductive tract as a critical but understudied niche. Evidence for a local microbiome largely derives from bacterial nucleic acid detection; however, the biological relevance of these signals remains debated,

Host Factor Induced Bacterial Extracellular Vesicles Promote Horizontal Gene Transfer in Vibrio cholerae

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
Antimicrobial stressors, that is, bile or mitomycin C, induce enlarged, nucleic acid‐rich bacterial extracellular vesicles in Vibrio cholerae that facilitate horizontal gene transfer in vitro and during intestinal colonisation. The findings provide a detailed comparison of control versus stress‐induced vesicles, identify bile as a host factor shaping ...

The Major Outer Membrane Protein MopB Is Required for Twitching Movement and Affects Biofilm Formation and Virulence in Two Xylella fastidiosa strains

Molecular Plant-Microbe Interactions, 2017
MopB is a major outer membrane protein (OMP) in Xylella fastidiosa, a bacterial plant pathogen that causes losses on many economically important crops. Based on in silico analysis, the uncharacterized MopB protein of X.

Carrier screening in the reproductive setting—Are there medical implications for the heterozygote?—A guide for clinicians

Pregnancy, Volume 2, Issue 3, May 2026.
Abstract Carrier screening for genetic conditions performed preconception or during pregnancy allows identification of fetal risk for inherited autosomal recessive and X‐linked conditions. The goal is to identify at‐risk patients/couples and offer them reproductive options such as preimplantation genetic diagnosis, prenatal testing, or targeted newborn

Possible role of Geobacter sulfurreducens in anaerobic corrosion of steels [PDF]

, 2007
Geobacteraceae are the most widespread microorganisms in soils and sediments in which microbial reduction of Fe(III) is an important process, either in the natural degradation of organic compounds or in their bioremediation.

3-D Structure Analysis of Escherichia Coli Type 1 Pili

Microscopy and Microanalysis, 2001
Abstract Type 1 pili are outer membrane organelles formed by 80% of all E. coli strains. They are up to 2 μm long, rod-like appendages covering the bacterial body like spines on a hedgehog (Fig. 1). Type 1 pili expressed by uropathogenic E. coli strains mediate adhesion to specific receptors of the bladder epithelium.

ssRNA bacteriophage metagenomes reveal a diverse set of novel protein families

Protein Science, Volume 35, Issue 5, May 2026.
Abstract The bacteriophages with single‐stranded RNA (ssRNA) genomes (class Leviviricetes) are among the simplest known viruses that encode only three core proteins: a receptor‐binding protein, a capsid protein, and an RNA‐dependent RNA polymerase. The number of isolated ssRNA phages has remained very low, but the accumulating RNA metagenome data have ...

Type IV Pili Can Mediate Bacterial Motility within Epithelial Cells

mBio, 2019
Pseudomonas aeruginosa is among bacterial pathogens capable of twitching motility, a form of surface-associated movement dependent on type IV pili (T4P). Previously, we showed that T4P and twitching were required for P.

A novel approach for distinguishing noise and information in forest MLS‐point clouds

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1595-1605, May 2026.
Abstract 3D laser scanning is a cornerstone of modern forest and ecological research, allowing detailed insight into forest structures and dynamics. Although point cloud processing and noise management are crucial steps in the exploitation of LiDAR data, traditional denoising methods are usually based on the assumption of a Gaussian noise distribution,
