The Contribution of Chemistry to the Detection and Enumeration of Legionella pneumophila in Environmental Water Samples: Experience With the MICA Method. [PDF]

Microbiologyopen
Legionella pneumophila is the principal species responsible for Legionnaires' disease, and measuring microbial load is fundamental to the analysis of environmental water samples. This study compared a new lipopolysaccharide bioprobe method (Microcolony Counter Analysis), which detects and counts L.

Sea water whirlpool spa as a source of Legionella infection

Journal of Water and Health, 2021
Bacterial pneumonia caused by the inhalation of aerosols contaminated with Legionella spp. is also known as Legionnaires' disease. In this study, we report a case of pneumonia caused by Legionella pneumophila sg.1 in a 58-year-old man who visited a sea ...

Characterisation and Comparative Evaluation of miRNA Contained in Small Extracellular Vesicles Isolated From Bovine Milk and Whey

Journal of Extracellular Biology, Volume 5, Issue 7, July 2026.
ABSTRACT Small extracellular vesicles (EVs) from bovine milk and whey are emerging as biologically active carriers of microRNA (miRNA), yet their composition and variability among different dairy sources remain incompletely understood. We conducted an integrated characterisation of EV‐associated miRNAs isolated from milk and whey collected from three ...

The Microbiota of Evaporative Cooling Systems and the Impact of Rainwater as an Alternative Water Source

Water Environment Research, Volume 98, Issue 7, July 2026.
The substitution of tap water with rainwater for evaporate cooling systems creates no disadvantage with regard to the microbial safety and might allow a reduction of financial and resource investments. ABSTRACT Climate change and an increasing global population are supposed to cause progressive water shortages in the future.

Polyphosphates Attenuate Interleukin‐12 Production in Macrophages Infected With Legionella pneumophila

The FASEB Journal, Volume 40, Issue 11, 15 June 2026.
Legionella pneumophila infection leads to the release of pathogen‐associated molecular patterns, which recruits the adaptor protein MYD88, initiating both activating (e.g., NF‐κB) and inhibitory (e.g., PI3K/AKT) signaling pathways that regulate IL‐12 gene expression.

Legionella Occurrence in Buildings: Implications of Public Water System Disinfectant and Residual

AWWA Water Science, Volume 8, Issue 3, May/June 2026.
ABSTRACT Legionella pneumophila is an opportunistic drinking water microorganism of serious health concern. Anticipated revisions to U.S. EPA's Microbial and Disinfection Byproduct Rules may propose a numeric minimum disinfectant residual—rather than the current “detectable”—in part to better control Legionella in drinking water distribution systems ...

Mitophagy‐Oxidative Stress Molecular Subtypes Define an Immunosuppressive Ecosystem and Vulnerabilities in Glioblastoma

Journal of Cellular and Molecular Medicine, Volume 30, Issue 10, May 2026.
ABSTRACT Glioblastoma (GBM) is an aggressive brain tumour with an immunosuppressive environment and poor prognosis; however, the roles of mitophagy and oxidative stress in its prognosis remain underexplored. This study analysed multi‐omics data from TCGA‐GBM (n = 168) and two GEO cohorts (GSE43378, n = 50; GSE147352, n = 85), compiling 603 mitophagy ...
