Paracoccidioides spp.: the structural characterization of extracellular matrix, expression of glucan synthesis and associated genes and adhesins during biofilm formation

Frontiers in Microbiology
The genus Paracoccidioides includes Paracoccidioides lutzii and the Paracoccidioides brasiliensis complex, which comprises four phylogenetic species. A key feature distinguishing planktonic growth from biofilm is the presence of a 3D extracellular matrix

Porphyromonas gingivalis and Ferroptosis: Evidence, Limitations, and Significance

Cell Biochemistry and Function, Volume 44, Issue 11, November 2026.
ABSTRACT Porphyromonas gingivalis (P. gingivalis) is a keystone pathogen in periodontal dysbiosis and has been linked to multiple systemic diseases. Ferroptosis is a form of regulated cell death driven by iron‐dependent lipid peroxidation, and accumulating evidence implicates it in P. gingivalis‐associated tissue injury.

Plant‐Derived Probiotics From Fermented Foods: Current Evidence on Antiviral Mechanisms and Gut–Lung Axis Modulation

Food Frontiers, Volume 7, Issue 6, November 2026.
Plant‐derived probiotics from fermented foods exert anti‐respiratory virus effects via immune regulation, antiviral metabolites, and gut–lung axis, highlighting their advantages, key technologies, and application prospects. ABSTRACT Respiratory viral infections represent a major global public health threat, causing widespread morbidity, mortality, and ...

The regulation by iron of the synthesis of adhesins and cytoadherence levels in the protozoan Trichomonas vaginalis.

, 1991
Levels of adherence of Trichomonas vaginalis to epithelial cells was found to be modulated by iron. Cytoadherence values were greater than or equal to twofold higher for trichomonads grown in a complex cultivation medium supplemented with iron.

High Prevalence of vanA‐Positive Vancomycin‐Resistant Enterococcus faecalis and Enterococcus faecium: Antibiotic Resistance, Biofilm Formation, and Virulence Profiles

Health Science Reports, Volume 9, Issue 11, November 2026.
ABSTRACT Background Data on antimicrobial resistance (AMR), biofilm formation, and virulence traits in clinical Enterococcus isolates from central Iran remain limited. This study evaluated AMR profiles, biofilm‐forming capacity, and the prevalence of virulence and resistance genes in clinical Enterococcus isolates from Arak, Iran.

The effect of calcium and magnesium on the aggregation of a purple phototrophic bacteria mixed consortium

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 11, Page 2301-2309, November 2026.
Abstract BACKGROUND An essential aspect of applying Purple Phototrophic Bacteria (PPB) technology for wastewater treatment is the biomass separation from the aqueous phase. Ca2+ and Mg2+ have been used to enhance the aggregation of different biological matrices. In this paper, the effect of Ca2+ and Mg2+ on the aggregation of a mixed culture of PPB was

Bacteriophage Resistance, Adhesin’s and Toxin’s Genes Profile of Staphylococcus aureus Causing Infections in Children and Adolescents

Microorganisms
Staphylococcus aureus is a common pathogen, often recovered from children’s infections. Βiofilm formation, antimicrobial resistance and production of adhesins and toxins contribute to its virulence.

Molecular Prevalence and Antimicrobial Resistance Patterns of Methicillin‐Resistant Staphylococcus aureus in Buffaloes from Bangladesh

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
Nasal swabs collected from 400 buffaloes were analysed to determine the prevalence, antimicrobial resistance and virulence characteristics of Staphylococcus aureus and MRSA. MRSA isolates exhibited extensive multidrug resistance and harboured multiple resistance and virulence genes, highlighting their pathogenic and zoonotic potential.

Structural and functional insights from the sequences and complex domain architecture of adhesin-like proteins from Methanobrevibacter smithii and Methanosphaera stadtmanae

Frontiers in Microbiology
Methanogenic archaea, or methanogens, are crucial in guts and rumens, consuming hydrogen, carbon dioxide, and other fermentation products. While their molecular interactions with other microorganisms are not fully understood, genomic sequences provide ...

Flagella‐Mediated Biofilm Formation and 3D Swarming Drive Virulence in the Honey Bee Pathogen Paenibacillus larvae

Environmental Microbiology, Volume 28, Issue 11, November 2026.
The flagella of the bacterial pathogen Paenibacillus larvae, the etiological agent of American foulbrood in honey bees, were characterized and identified as virulence factors. These cellular appendages play key roles in biofilm formation and 3D swarming, two multicellular behaviours of P. larvae that contribute to pathogenesis.
