Nanostructured Ti–6Al–4V Reduces Adhesion of Several Bacterial Species: An In Vitro Study

Small Science, Volume 6, Issue 8, August 2026.
Alkaline etching transforms Ti–6Al–4V into nanostructured, highly hydrophilic surfaces with thicker oxide layers and selective alloy depletion. These physicochemical changes reduce early bacterial adhesion across multiple species by limiting effective nanoscale contact points, while osteoblast‐like cells retain good attachment and spreading.

Occurrence and Distribution of Environmental Pseudomonas aeruginosa From Hospitals in Bangladesh Reveals Diverse Strain Families, Multidrug Resistance, and Biofilm Formation

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Environmental reservoirs in Bangladeshi hospitals harbor phylogenetically diverse, multidrug‐resistant Pseudomonas aeruginosa with extensive biofilm‐forming capacity and class 1 integron‐associated resistance genes. These findings highlight hospital environments as persistent sources of antimicrobial resistance dissemination and underscore the need for

Xylella fastidiosa pil-chp operon is involved in regulating key structural genes of both type I and IV pili [PDF]

, 2017
Xylella fastidiosa is the causal agent of Pierce\u27s disease (PD) in grapevines. It has type I and type IV pili, which are both virulence factors involved in the PD-associated processes of motility, aggregation, and biofilm formation.

Screening of a Haloferax volcanii Transposon Library Reveals Novel Motility and Adhesion Mutants

Life, 2016
Archaea, like bacteria, use type IV pili to facilitate surface adhesion. Moreover, archaeal flagella—structures required for motility—share a common ancestry with type IV pili.

Circular RNAs in Lotus japonicus Responses to Nutrient Supply and Mesorhizobium Symbiosis

Plant, Cell &Environment, Volume 49, Issue 8, Page 4823-4839, August 2026.
ABSTRACT Symbiotic interactions between legumes and rhizobia enable nitrogen fixation under low nutrient conditions. The establishment and function of symbiotic interactions require coordinated changes in gene expression in both the host and the microbe. Circular RNAs (circRNAs) are endogenous gene‐specific molecules that can regulate transcription and

Genetic and mass spectrometry analyses of the unusual type IV-like pili of the Archaeon Methanococcus maripaludis [PDF]

, 2011
The structure of pili from the archaeon Methanococcus maripaludis is unlike that of any bacterial pili. However, genetic analysis of the genes involved in the formation of these pili has been lacking until this study.

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

A genetic and functional analysis of type IV pili produced by Aeromonas bacteria [PDF]

, 1999
Bacteria belonging to the genus Aeromonas are ubiquitous water-borne organisms that are also present in many foods. Some strains are human gastrointestinal pathogens. However, the disease-causing mechanisms of these bacteria are not well understood. This

Meningococci drive host membrane tubulation to recruit their signaling receptors

Nature Communications
Once passed into the bloodstream, bacterial pathogens have a limited time to interact with permissive receptors at the surface of host cells. Neisseria meningitidis has developed an extremely effective strategy allowing it to find its receptors in a few ...
