Photophobotaxis of single‐celled and filamentous cyanobacteria

Photochemistry and Photobiology, EarlyView.
LED illumination from below induces central accumulation of cyanobacterial species. Abstract Phototaxis refers to an organism's movement toward a light source, while photophobotaxis involves movement into illuminated regions. Although phototaxis in cyanobacteria has been widely studied, photophobotaxis has been investigated in only a few species.

The Biomechanical Properties of E. coli Pili for Urinary Tract Attachment Reflect the Host Environment

, 2007
Uropathogenic Escherichia coli express pili that mediate binding to host tissue cells. We demonstrate with in situ force measuring optical tweezers that the ability of P and type 1 pili to elongate by unfolding under exposure to stress is a shared ...

Cystitis in guinea pigs (Cavia porcellus): Clinical findings and treatment outcomes

Veterinary Record, Volume 199, Issue 1, Page e30-e38, 4/11 July 2026.
Abstract Background This retrospective study examined the incidence, diagnostic methods, bacterial isolates, treatments and outcomes associated with cystitis in guinea pigs presented at a single clinic between 2009 and 2022. Methods The clinic's medical records database was reviewed using easyvet software to identify cases eligible for inclusion in the

Microreview: type IV secretion systems: versatility and diversity in function

, 2010
Type IV secretion systems (T4SSs) are large protein complexes which traverse the cell envelope of many bacteria. They contain a channel through which proteins or protein–DNA complexes can be translocated.

Direct Observation of Electrically Conductive Pili Emanating from Geobacter sulfurreducens

, 2021
Geobacter sulfurreducens is a model microbe for elucidating the mechanisms for extracellular electron transfer in several biogeochemical cycles, bioelectrochemical applications, and microbial metal corrosion.

Pilus phase variation switches gonococcal adherence to invasion by caveolin-1-dependent host cell signaling.

PLoS Pathogens, 2013
Many pathogenic bacteria cause local infections but occasionally invade into the blood stream, often with fatal outcome. Very little is known about the mechanism underlying the switch from local to invasive infection. In the case of Neisseria gonorrhoeae,

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).

The type 1 pili regulator gene fimX and pathogenicity island PAI-X as molecular markers of uropathogenic Escherichia coli

, 2013
Uropathogenic Escherichia coli (UPEC) fall within a larger group of isolates producing extraintestinal disease. UPEC express type 1 pili as a critical virulence determinant mediating adherence to and invasion into urinary tract tissues.

Structure‐informed engineering of plant–microbe interactions

The Plant Journal, Volume 127, Issue 1, July 2026.
SUMMARY This review critically evaluates how structural biology has enabled interface‐informed engineering of plant–microbe interactions, with a clear emphasis on the relative maturity of plant–pathogen research compared with symbiosis engineering. In plant immunity, atomic resolution structures of apoplastic receptors, host targets, and intracellular ...
