Virulence Regulation and Lifestyle Transitions: The Role of c‐di‐GMP and Two‐Component Systems in Erwinia amylovora and Their Evolutionary Context Within Enterobacterales

open access: yesMolecular Plant Pathology, Volume 27, Issue 2, February 2026.
Erwinia amylovora infects apple blossoms by activating the T3SS, then spreads systemically via amylovoran‐mediated biofilms. Transitions between motile and sessile states are regulated by key two‐component systems and c‐di‐GMP. This review summarises infection biology, virulence factors, regulatory networks and evolutionary insights underlying fire ...

Serine Hydroxymethyltransferase ShrA (PA2444) Controls Rugose Small-Colony Variant Formation in Pseudomonas aeruginosa

open access: yesFrontiers in Microbiology, 2018
Pseudomonas aeruginosa causes many biofilm infections, and the rugose small-colony variants (RSCVs) of this bacterium are important for infection. We found here that inactivation of PA2444, which we determined to be a serine hydroxymethyltransferase ...

Synthesis of Triazole-Linked Analogues of c-di-GMP and Their Interactions with Diguanylate Cyclase [PDF]

open access: yesJournal of Medicinal Chemistry, 2015
Cyclic di-GMP (c-di-GMP) is a widespread second messenger that plays a key role in bacterial biofilm formation. The compound's ability to assume multiple conformations allows it to interact with a diverse set of target macromolecules. Here, we analyzed the binding mode of c-di-GMP to the allosteric inhibitory site (I-site) of diguanylate cyclases (DGCs)

Pseudomonas aeruginosa Biofilms in Cystic Fibrosis: Interactions, Methods, and Therapeutic Strategies

open access: yesBioMed Research International, Volume 2026, Issue 1, 2026.
This review explores the role of Pseudomonas aeruginosa biofilms in cystic fibrosis (CF) pathogenesis. Biofilms, the main bacterial lifestyle in CF lungs, are key in therapy failure, immune evasion, and chronic infection persistence. This review examines biofilm structure, emphasizing extracellular polymeric substances (Psl, Pel, alginate, eDNA) and ...

Enhanced Exoelectrogenic Activity of Cupriavidus metallidurans in Bioelectrochemical Systems through the Expression of a Constitutively Active Diguanylate Cyclase

open access: yes, 2022
Electroactive bacteria have a wide range of applications, including electricity production, bioremediation, and the sensing of toxic compounds. Bacterial biofilm formation is often mediated by the second messenger cyclic guanosine monophosphate (c-di-GMP)

Cyclic di-GMP-dependent signaling pathways in the pathogenic Firmicute Listeria monocytogenes.

open access: yesPLoS Pathogens, 2014
We characterized key components and major targets of the c-di-GMP signaling pathways in the foodborne pathogen Listeria monocytogenes, identified a new c-di-GMP-inducible exopolysaccharide responsible for motility inhibition, cell aggregation, and ...

The Diverse Roles of the Histone‐Like Nucleoid Structuring (H‐NS) Protein in Vibrio parahaemolyticus

open access: yesGenetics Research , Volume 2026, Issue 1, 2026.
The histone‐like nucleoid structuring (H‐NS) protein is a global transcriptional regulator critical for bacterial genome organization and gene expression. In Vibrio parahaemolyticus, H‐NS represses virulence factors such as thermostable direct hemolysin (TDH), type III secretion systems (T3SS1/T3SS2), and type VI secretion systems (T6SS1/T6SS2).

Divergent Fates of Hardjo Leptospires: Early Transcriptomic Response of Leptospira interrogans in an Ovine Dialysis Membrane Chamber Model

open access: yesTransboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Leptospira interrogans serovar Hardjo and Leptospira borgpetersenii serovar Hardjo are major bovine‐ and ovine‐adapted pathogens that differ markedly in genome content. To investigate early events during host exposure, we compared the survival of both species using an ovine peritoneal dialysis membrane chamber (DMC) model, which exposes leptospires to ...

Genetic Determinants Associated With the Biofilm Formation Impairment in Pseudomonas aeruginosa Clinical Isolates

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
Numerous studies have reported biofilm formation impairment in Pseudomonas aeruginosa clinical isolates, however, the genetic basis of this phenomenon remains largely unexplored. In this study, we aimed to identify associations between impaired‐biofilm formation and loss‐of‐function mutations in biofilm regulatory and effector genes.
