Structural basis of Acinetobacter type IV pili targeting by an RNA virus

Nature Communications
Acinetobacters pose a significant threat to human health, especially those with weakened immune systems. Type IV pili of acinetobacters play crucial roles in virulence and antibiotic resistance.

Host Receptor Pili for Cryo-EM Single-Particle Reconstruction

Bio-Protocol
Single-stranded RNA bacteriophages (ssRNA phages) infect their hosts by binding to the host receptor pili. Purification of pili usually involves mechanical shearing of pili from cells followed by precipitation.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

The Oral‐Gut Axis: Bidirectional Interactions Between Microbiome and Diseases

Journal of Periodontal Research, EarlyView.
This study aims to summarize the mechanisms underlying ectopic colonization of the gut by oral pathobionts and the microbial and host factors that regulate this process. ABSTRACT Increased colonization of typically oral microorganisms is frequently observed in the gut mucosa or lumen of individuals with gastrointestinal disorders, including patients ...

Archaeal Cytoskeletal Protein CetZ1 Influences Assembly of the Motility Machinery

Molecular Microbiology, EarlyView.
The Haloferax volcanii tubulin‐like protein CetZ1 is required for rod‐cell morphogenesis and motility. We show that CetZ1 loss or GTPase inactivation impairs assembly of the motility machinery, including the archaellum base protein ArlD, the chemotaxis adaptor CheW1, and the response regulator CheY.

Understanding Exosomes in Hair Regeneration

Periodontology 2000, EarlyView.
Abstract Background Alopecia is a prevalent condition correlated with significant psychosocial challenges, while contemporary treatments exhibit variable efficacy, require extended use, and may cause adverse effects. This review aimed to comprehensively assess exosome‐mediated interventions as a novel cell‐free regenerative approach for hair ...

Modelling Climate‐Resilient Habitats for Conservation and Restoration of Isoberlinia doka Craib and Stapf and Isoberlinia tomentosa (Harms) Craib and Stapf in Benin

Climate Resilience and Sustainability, Volume 5, Issue 2, December 2026.
Despite having similar climatic niches, woody plant species can exhibit contrasting responses to climate change. Using MaxEnt and spatial prioritization, we evaluated Isoberlinia doka and I. tomentosa under future climate scenarios (2041–2060). Despite high niche overlap (D = 0.635; I = 0.788), I. doka experienced severe habitat contraction, whereas I.

Distinct Genomic Features Characterize Two Clades of Corynebacterium diphtheriae: Proposal of Corynebacterium diphtheriae Subsp. diphtheriae Subsp. nov. and Corynebacterium diphtheriae Subsp. lausannense Subsp. nov.

Frontiers in Microbiology, 2018
Corynebacterium diphtheriae is the etiological agent of diphtheria, a disease caused by the presence of the diphtheria toxin. However, an increasing number of records report non-toxigenic C. diphtheriae infections. Here, a C.

Protective Effects of Lactobacillus‐Derived Probiotics and Postbiotics on Renal and Reproductive Function in Escherichia coli–Infected Rats

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
A Lactobacillus‐derived probiotic and postbiotic mixture alleviates E. coli–induced renal and reproductive dysfunction by modulating oxidative stress, inflammatory responses, and apoptosis, leading to improved tissue integrity and sperm quality. ABSTRACT Background Escherichia coli infections of the genitourinary tract are a major cause of renal and ...
