Legionella affects biofilm structural response to detachment upon shear stress increase

Biofilm
Poor hydraulic management at water systems is associated with an increased risk of Legionnaires' disease caused by Legionella. Stagnation periods, followed by sudden water flow, can promote biofilm detachment and the release of Legionella into the bulk ...

Motorized DNAzymes Drive Enhanced Electrochemical Biosensing for Rapid Bacterial Detection

Small Methods, Volume 10, Issue 6, 24 March 2026.
The micromotor DNAzyme analyzer (Motolyzer) enables sensitive electrochemical detection of Legionella pneumophila proteins in unprocessed samples with high specificity. Upon target recognition, DNAzymes actively release redox barcodes, which are detected on DNA‐functionalized electrodes.

Legionella Pneumophila Transcriptome during Intracellular Multiplication in Human Macrophages [PDF]

, 2011
Legionella pneumophila is the causative agent of Legionnaires’ disease, an acute pulmonary infection. L. pneumophila is able to infect and multiply in both phagocytic protozoa, such as Acanthamoeba castellanii, and mammalian professional phagocytes.

Cas9 beyond CRISPR – SUMOylation, effector‐like potential and pathogenic adaptation

The FEBS Journal, Volume 293, Issue 5, Page 1285-1296, March 2026.
This Viewpoint explores the possibility that Cas9, beyond its canonical role in CRISPR immunity, may act as a host‐modulating effector during infection by Cas9‐encoding bacteria. Such a nucleomodulin‐like function could be influenced by eukaryotic post‐translational modifications, particularly SUMOylation, with potential implications for host–pathogen ...

A plasmid in Legionella pneumophila [PDF]

Infection and Immunity, 1980
Sixteen strains from the six serogroups of Legionella pneumophila were examined for the presence of extrachromosomal genetic elements by a modified cleared lysate procedure, dye-buoyant centrifugation, and agarose gel electrophoresis. Two strains, Atlanta-1 and Atlanta-2 from serogroup II, each contained a plasmid of cryptic function with a molecular ...

Patatin‐domain‐containing (phospho)lipases under control: Mammalian co‐regulators and pathogenic activation mechanisms

FEBS Open Bio, Volume 16, Issue 2, Page 279-298, February 2026.
Patatin domain‐containing (phospho)lipases are lipid‐hydrolyzing enzymes central to metabolism, membrane remodeling, and signaling. Their activity relies on precise co‐activation mechanisms involving protein–protein interactions and conformational rearrangements.

Serospecific antigens of Legionella pneumophila [PDF]

Journal of Bacteriology, 1986
Serospecific antigens isolated by EDTA extraction from four serogroups of Legionella pneumophila were analyzed for their chemical composition, molecular heterogeneity by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and immunological properties. The antigens were shown to be lipopolysaccharides and to differ from the lipopolysaccharides of

Advances in Double‐Stranded DNA Targeting Technologies

Exploration, Volume 6, Issue 1, February 2026.
Double‐stranded DNA (dsDNA) plays a crucial role in genetic information storage and disease management, but its inherent stability limits access to internal bases. To overcome this challenge, various high‐specificity molecular targeting technologies have been developed to destabilize the DNA structure.
