BACKGROUND AND OBJECTIVES Pathogens in source waters represent a health risk for drinking water consumers that may result in waterborne diseases, if not sufficiently removed within water treatment plants. (chalmers.se)
Assuming a total mixing of wastewater pathogens discharged into the river, the downstream microbial concentration was approximated and compared to sampling data on indicator and pathogens from the river Göta älv for the same data period. (chalmers.se)
Present simulation results also suggest a first prioritization for reduction of microbial loads within urban wastewater systems along this river, such as the need for local additional wastewater treatment steps in order to bring down the spread of pathogens. (chalmers.se)
However, since great discriminative power is required to study pathogen and host simultaneously throughout the infection process, the depth of quantitative gene expression profiling has proven to be unsatisfactory when focusing on bacterial pathogens, thus preferentially requiring specific strategies or the development of novel methodologies based on complementary omics approaches. (preprints.org)
Water quality studies today tend to focus on the indicators of pathogens, but Joan's work targets actual threat agents such as viruses, mapping water quality and health risks in waterways throughout the world. (msu.domains)
Her applied research interests include study of microbial pathogens in recreational waters and climatic factors impacting water quality. (msu.domains)
The assessment of drinking water microbial quality is generally performed by detecting and/or quantifying faecal contamination indicators which may not provide an adequate evaluation of the health risks posed by several waterborne pathogens, for example Norovirus , Vibrio cholerae , and Cryptosporidium .

Pathogen6
To do this, a quantitative microbial risk assessment (QMRA) framework was developed in National Capital Region, India based on bacterial indicator and pathogen data from fresh produce wash samples collected at local markets. (nih.gov)
Through Monte Carlo simulations the daily microbial loads to the river were calculated using pathogen concentrations and discharge information from the wastewater systems for each single discharge point. (chalmers.se)
