Metagenomic and Phenotypic Insights Into Biofilm‐Forming Pathogens in Patients With Nosocomial Sepsis

BioMed Research International, Volume 2026, Issue 1, 2026.
Biofilm‐related infections significantly contribute to bacterial diseases, with estimates suggesting that at least 80% of such infections are associated with biofilms. These infections often involve opportunistic pathogens, which not only influence the type of infection but also impact the microenvironment by interacting with other polymicrobial ...

Quorum Sensing and Expression of Virulence in Pectobacteria

Sensors, 2012
Quorum sensing (QS) is a population density-dependent regulatory mechanism in which gene expression is coupled to the accumulation of a chemical signaling molecule. QS systems are widespread among the plant soft-rotting bacteria.

Quorum Sensing Regulates the Hydrolytic Enzyme Production and Community Composition of Heterotrophic Bacteria in Coastal Waters

Frontiers in Microbiology, 2021
Heterotrophic microbial communities play a central role in biogeochemical cycles in the ocean by degrading organic matter through the synthesis of extracellular hydrolytic enzymes.

Development of an ex vivo porcine lung model for studying growth, virulence, and signaling of Pseudomonas aeruginosa [PDF]

, 2014
Research into chronic infection by bacterial pathogens, such as Pseudomonas aeruginosa, uses various in vitro and live host models. While these have increased our understanding of pathogen growth, virulence, and evolution, each model has certain ...

Design and Synthesis of Triazole‐Based p‐tert‐Butylcalix[4]Arene Conjugates and Evaluation of Their Antimicrobial, Antibiofilm, and Anti‐Quorum‐Sensing Activities

Biotechnology and Applied Biochemistry, Volume 72, Issue 6, Page 1546-1559, December 2025.
ABSTRACT Macrocyclic calix[n]arenes have many applications, with diverse structures that can easily be functionalized either on upper or lower rims, mostly to impart solubility and improve biological activities. In this study, triazole‐based p‐tert‐butylcalix[4]arene conjugates (AT10a and AT10b) and their p‐tert‐butylphenol analogs (AT10b and AT11b ...

Pandoraea sp. RB-44, A Novel Quorum Sensing Soil Bacterium

Sensors, 2013
Proteobacteria are known to communicate via signaling molecules and this process is known as quorum sensing. The most commonly studied quorum sensing molecules are N-acylhomoserine lactones (AHLs) that consists of a homoserine lactone moiety and an N ...

AhaP, A Quorum Quenching Acylase from Psychrobacter sp. M9-54-1 That Attenuates Pseudomonas aeruginosa and Vibrio coralliilyticus Virulence

Marine Drugs, 2021
Although Psychrobacter strain M9-54-1 had been previously isolated from the microbiota of holothurians and shown to degrade quorum sensing (QS) signal molecules C6 and C10-homoserine lactone (HSL), little was known about the gene responsible for this ...

Attenuated Strains of Pseudomonas aeruginosa: A Promising Cell Factory for Rhamnolipid Production

Microbial Biotechnology, Volume 18, Issue 11, November 2025.
PGN strains are generated by the deletion of virulence factor genes. The metabolic pathways and regulatory frameworks that lead to high‐efficiency production of rhamnolipids in P. aeruginosa are preserved in these strains. Therefore, PGN strains are promising bio‐safe cell factories for the industrial production of rhamnolipids.

Serratia spp. bacteria evolved in Aotearoa‐New Zealand for infection of endemic scarab beetles

New Zealand Journal of Zoology, Volume 52, Issue 2, Page 121-143, June 2025.
ABSTRACT The Melolonthinae branch of the beetle family Scarabaeidae has evolved in isolation in Aotearoa, radiating into >100 endemic species, since Aotearoa separated from Gondwanaland 82 million years ago. The group includes important pasture pests, such as the New Zealand grass grub Costelytra giveni and the manuka beetle Pyronota festiva.
