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...
Opportunistic pathogens exhibit distinct growth dynamics in rainwater and tap water storage systems
01/10/2021 - Opportunistic pathogens (OPs) are emerging microbial contaminants in engineered water systems, yet their growth potential in rainwater systems has not been evaluated. The purpose of this study was...
The wastewater protist Rhogostoma minus (Thecofilosea, Rhizaria) is abundant, widespread, and hosts Legionellales
15/09/2021 - Wastewater is treated by concerted actions of the microbial communities within bioreactors. Although protists (unicellular eukaryotes) are good bioindicators and important players influencing...
Optimal schedule and temperature control of stratified water heaters
- Water heating is a major component of domestic electrical energy usage, in some countries contributing to 25% of the residential sector energy consumption. Demand response strategies can reduce...
Efficient cooling tower operation at alkaline pH for the control of Legionella pneumophila and other pathogenic genera
01/06/2021 - Efficient control of pathogenic bacteria, specifically Legionella pneumophila, is one of the main concerns when operating industrial cooling towers. Common practices to limit...
Developing Bayesian networks in managing the risk of Legionella colonisation of groundwater aeration systems
01/04/2021 - An Australian water utility has developed a Legionella High Level Risk Assessment (LHLRA) which provides a semi-qualitative assessment of the risk of Legionella proliferation and...
Dynamic modelling of Legionella pneumophila thermal inactivation in water
15/02/2021 - A predictive mathematical model describing the effect of temperature on the inactivation of Legionella pneumophila in water was developed. Thermal inactivation of L. pneumophila...
A comprehensive evaluation of monochloramine disinfection on water quality, Legionella and other important microorganisms in a hospital
01/02/2021 - Opportunistic pathogens such as Legionella are of significant public health concern in hospitals. Microbiological and water chemistry parameters in hot water throughout an Ohio hospital...
