Motorized DNAzymes Drive Enhanced Electrochemical Biosensing for Rapid Bacterial Detection. [PDF]

Small Methods
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.

Presence of Viable, Clinically Relevant Legionella Bacteria in Environmental Water and Soil Sources of China

Microbiology Spectrum, 2022
The distribution of pathogenic Legionella in the environmental soil and water of China has not been documented yet. In this study, Legionella was detected in 129 of 575 water (22.43%) and 41 of 442 soil samples (9.28%) by culture.

Validating a clinical prediction score for Legionella-related community acquired pneumonia

BMC Infectious Diseases, 2022
Background Legionella-related community acquired pneumonia (CAP) is a disease with an increasing incidence and a high mortality rate, especially if empirical antibiotic therapy is inadequate.

Increased flushing frequency of a model plumbing system initially promoted the formation of viable but non culturable cells but ultimately reduced the concentration of culturable and total Legionella DNA

Heliyon
Legionella is the causative agent of Legionnaires’ disease, and its prevalence in potable water is a significant public health issue. Water stagnation within buildings increases the risk of Legionella. However, there are limited studies investigating how

Legionella Infection Risk from Domestic Hot Water

Emerging Infectious Diseases, 2004
We investigated Legionella and Pseudomonas contamination of hot water in a cross-sectional multicentric survey in Italy. Chemical parameters (hardness, free chlorine, and trace elements) were determined. Legionella spp.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...
