Genetic characterization of Legionella pneumophila isolated from a common watershed in comunidad Valenciana, Spain [PDF]

, 2013
Legionella pneumophila infects humans to produce legionellosis and Pontiac fever only from environmental sources. In order to establish control measures and study the sources of outbreaks it is essential to know extent and distribution of strain variants

The amoebal MAP kinase response to Legionella pneumophila is regulated by DupA [PDF]

, 2009
The amoeba Dictyostelium discoideum can support replication of Legionella pneumophila. Here we identify the dupA gene, encoding a putative tyrosine kinase/dual-specificity phosphatase, in a screen for D.

alpha-Hydroxyketone Synthesis and Sensing by Legionella and Vibrio [PDF]

, 2012
Bacteria synthesize and sense low molecular weight signaling molecules, termed autoinducers, to measure their population density and community complexity. One class of autoinducers, the α-hydroxyketones (AHKs), is produced and detected by the water-borne

A multi-center validation study on the discrimination of Legionella pneumophila sg.1, Legionella pneumophila sg. 2-15 and Legionella non-pneumophila isolates from water by FT-IR spectroscopy

Frontiers in Microbiology, 2023
This study developed and validated a method, based on the coupling of Fourier-transform infrared spectroscopy (FT-IR) and machine learning, for the automated serotyping of Legionella pneumophila serogroup 1, Legionella pneumophila serogroups 2-15 as well

Quantification of viable Legionella pneumophila cells using propidium monoazide combined with quantitative PCR. [PDF]

, 2011
One of the greatest challenges of implementing fast molecular detection methods as part of Legionella surveillance systems is to limit detection to live cells. In this work, a protocol for sample treatment with propidium monoazide (PMA) in combination

Influence of Metal Concentration and Plumbing Materials on Legionella Contamination

Microorganisms, 2022
Legionella colonization of water supply pipes is a significant public health problem. The objective of this work was to evaluate Legionella colonization in hotel hot water systems and to investigate the relationship between metal concentrations, piping ...

Necrotrophic Growth of Legionella pneumophila [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACT This study examined whether Legionella pneumophila is able to thrive on heat-killed microbial cells (necrotrophy) present in biofilms or heat-treated water systems. Quantification by means of plate counting, real-time PCR, and flow cytometry demonstrated necrotrophic growth of L ...

The Legionella genus core effectors display functional conservation among orthologs by themselves or combined with an accessory protein

Current Research in Microbial Sciences, 2022
The intracellular pathogen Legionella pneumophila, as well as other Legionella species, utilize the Icm/Dot type-IV secretion system to translocate an exceptionally large and diverse repertoire of effectors into their host cells.

Extracellular enzymes of Legionella pneumophila [PDF]

Infection and Immunity, 1981
All strains of Legionella pneumophila tested produced detectable levels of extracellular protease, phosphatase, lipase, deoxyribonuclease, ribonuclease, and beta-lactamase activity. Weak starch hydrolysis was also demonstrated for all strains. Elastase, collagenase, phospholipase C, hyaluronidase, chondroitinase, neuraminidase, or coagulase were not ...

A Portable Colorimetric Device for Rapid Bacterial Detection with Cleavable Functional Nucleic Acid Probes for A Common Bacterial Endoribonuclease

Angewandte Chemie, EarlyView.
A simple, rapid, and portable gold‐coated filter tip‐based assay (GFTA) is developed for bacterial detection. The GFTA leverages cleavable functional nucleic acid probes as molecular recognition elements to target RNase H2, a highly conserved bacterial endoribonuclease, enabling sensitive and specific colorimetric detection of bacterial pathogens ...
