Uncovering wastewater treatment plants as possible sources of legionellosis clusters through spatial statistics approach and environmental analysis
04/07/2024 - Wastewater treatment plants (WWTPs) are suspected reservoirs of Legionella pneumophila (Lp). The required aeration and mixing steps lead to the emission and dispersion of bioaerosols potentially...
The influence of in situ purification system on pathogen in the river fed by the drainage of sewage plant
10/04/2024 - An in situ integrated system, consisting of ecological floating islands (EFI), ecological riverbeds (ER), and ecological filter dams (EFD), was built in a ditch only receiving the effluent of...
Building Water Quality Commissioning in Healthcare Settings: Reducing Legionella and Water Contaminants Utilizing a Construction Scheduling Method
07/10/2023 - Construction activities in healthcare settings potentially expose building occupants to life-threatening waterborne pathogens, including Legionella. The lack of a building water quality commissioning...
Managing Building Water Disruptions in a Post-COVID World: Water Quality and Safety Risk Assessment Tool for Academic Institutions and School Settings
31/03/2023 - Fluctuating building occupancy during the COVID-19 pandemic contributed to poor water quality and safety conditions in building water distribution systems (BWDSs). Natural disasters, man-made events,...
Legionella monitoring results by water quality characteristics in a large public water system
13/03/2023 - Legionella, the causative agent of Legionnaires’ disease, is an emerging concern for water utilities. Passaic Valley Water Commission (PVWC) is a public drinking water supplier, which provides...
Contribution of pollution gradient to the sediment microbiome and potential pathogens in urban streams draining into Lake Victoria (Kenya)
22/12/2022 - In sub-Saharan Africa (SSA), urban rivers/streams have long been subjected to anthropogenic pollution caused by urbanization, resulting in significantly altered chemical and biological properties...
Evaluation of Biopolymer Materials and Synthesis Techniques to Develop a Rod-Shaped Biopolymer Surrogate for Legionella pneumophila
24/06/2022 - Biopolymer microparticles have been developed for applications that require biocompatibility and biodegradability, such as drug delivery. In this study, we assessed the production of microparticles...
Aberrant hepatic lipid metabolism associated with gut microbiota dysbiosis triggers hepatotoxicity of novel PFOS alternatives in adult zebrafish
01/08/2022 - Perfluorooctane sulfonate (PFOS) has been reported to induce hepatotoxicity in wildlife and humans. Novel PFOS alternatives have been widely used following restrictions on PFOS, but little is...
A sequential utilization of the UV-A (365 nm) fluence rate for disinfection of water, contaminated with Legionella pneumophila and Legionella dumoffii
- Legionella species are the etiological agent of Legionnaires' disease, a pathology easily contracted from water circuits and by the inhalation of aerosol droplets. This bacterium mainly...
EMA- Versus PMA-Amplicon-Based Sequencing to Elucidate the Viable Bacterial Community in Rainwater
- Ethidium monoazide bromide (EMA) and propidium monoazide (PMA), in combination with amplicon-based sequencing (ABS) and quantitative polymerase chain reaction (qPCR) assays, were compared for the...
Microbiological quality of roof tank water in an urban village in southeastern China
- Urban villages are unique residential neighborhoods in urban areas in China. Roof tanks are their main form of water supply, and water quality deterioration might occur in this system because of...
Microbiomes in drinking water treatment and distribution: A meta-analysis from source to tap
01/04/2022 - A meta-analysis of existing and available Illumina 16S rRNA datasets from drinking water source, treatment and drinking water distribution systems (DWDS) were collated to compare changes in...
Tenets of a holistic approach to drinking water-associated pathogen research, management, and communication
01/03/2022 - In recent years, drinking water-associated pathogens that can cause infections in immunocompromised or otherwise susceptible individuals (henceforth referred to as DWPI), sometimes referred to as...
A comprehensive investigation of the microbial risk of secondary water supply systems in residential neighborhoods in a large city
15/10/2021 - Secondary water supply systems (SWSSs) are characterized by long water stagnation and low levels of chlorine residuals, which may pose a high microbial risk to terminal users. In this study, the...
