  • pathogen
  • Alternatively, determining the relative infectivity of persistent pathogen subpopulations and the rates of phenotypic conversion will help ascertain how much disease risk is associated with the long tails of biphasic decay. (biomedcentral.com)
  • The net effect of heavy rainfall is thus a higher risk of infection, because the pathogen has little time to die-off in the fast flowing waters. (thefishsite.com)
  • Site-specific pathogen monitoring of source waters was identified as an important factor for the accurate estimation of risk. (diva-portal.org)
  • Noroviruses, an emerging waterborne pathogen, were shown to have fluctuating concentrations in surface water, with significant peaks during the wintertime. (diva-portal.org)
  • fecal
  • Her research aims to develop methods for modeling community and occupational health risks associated with fecal sludge reuse technologies. (berkeley.edu)
  • Distribution of human-specific bacteroidales and fecal indicator bacteria in an urban watershed impacted by sewage pollution, determined using RNA- and DNA-based quantitative PCR assays. (semanticscholar.org)
  • estimate
  • The Odds Ratio for one unit of dose [OR = 1.76 (95% CI: 1.21, 2.55)] showed a very good consistency with the risk assessment estimate computed after the literature dose-response, provided application of a 20 % abatement factor to the cysts counts that were measured in the epidemiological study.

  • He is exploring frameworks to quan-ti-fy- the micro-bial risks involved in collection and reuse of septage, and estimate poten-tial Phos-pho-rous and Nitro-gen that can be aug-mented by reuse. (berkeley.edu)
  • Data on air temperature and the prevalence of Campylobacter in poultry flocks is entered to estimate risks of eating chicken fillets. (thefishsite.com)
  • disinfectants
  • Lauren is interested in the impact of disinfectants on microbial communities in drinking water distribution systems and in potable reuse systems. (berkeley.edu)
  • assays
  • Novel virulence, antibiotic resistance and toxin gene-specific PCR-based assays for rapid pathogenicity assessment of Arcobacter faecis and Arcobacter lanthieri. (nih.gov)
  • Development of quantitative PCR assays targeting the 16S rRNA genes of Enterococcus spp. (semanticscholar.org)
  • diseases
  • For all diseases, the tool considers the risk in relation to the 'dose', for example, the volume of drinking water typically consumed per person per day. (thefishsite.com)
  • infection
  • The dose-response functions that are currently used in risk assessment studies for protozoa stem from clinical trials where adult healthy volunteers have been exposed to known amounts of well characterized micro-organisms and followed to ascertain the development of infection (faecal excretion, seroconversion). (biomedcentral.com)
  • Users can model each pathogen's 'journey' with the tool, considering the complex influences on its spread from source to infection to reach an overall risk rating. (thefishsite.com)
  • This allows estimates of infection risk under current and future climates to be compared. (thefishsite.com)
  • When working or spending time in the garden the annual risk of infection by Ascaris was still slightly above 10 -4 in these scenarios, although the incidence rate for Ascaris is very low in the population in question. (diva-portal.org)
  • methods
  • However, risk could be indirectly ascertained by developing methods to separately monitor labile and persistent subpopulations. (biomedcentral.com)
  • quantify
  • To improve future estimates, there is a need for robust epidemiological studies that quantify the health risks associated with small, private water systems, groundwater systems and the influence of distribution system intrusions on risk. (iwaponline.com)
  • We conclude that, while the nanoliter reaction volumes, rapid thermocycling and one-size-fits-all reaction conditions of MFQPCR necessitates more stringent primer selection criteria than is commonly applied in soil microbial ecology, the ability to quantify up to 96 targets in 96 samples makes MFQPCR a valuable tool for monitoring shifts in functional community abundances.

  • reuse
  • Her research interests include water reuse, development engineering, and waterborne pathogens. (berkeley.edu)
  • Olga's research involves spatial analysis and life-cycle assessment of decentralized infrastructure, with specific applications on water reuse and nitrogen recovery. (berkeley.edu)
  • Rose studies the microbial communities in water for potable reuse using meta-omics techniques. (berkeley.edu)
  • waters
  • Surface waters can become contaminated by this bacterium via human and animal faecal waste, which poses a risk to swimmers. (thefishsite.com)
  • health
  • In addition, there are unanswered questions regarding the susceptibility of vulnerable sub-populations to these pathogens and the influence of extreme weather events (precipitation) on AGI-related health risks. (iwaponline.com)
  • Dose-response assessment involves determining the relationship between dose of the microorganism (hazard) and the incidence or extent of the adverse health effect. (wcponline.com)
  • Karina's research focuses on microbial ecosystems at the interface of drinking water infrastructure and environmental health in low- and middle-income countries. (berkeley.edu)
  • Issues of operation and mangement are likely to determine the health risks in decentralised systems. (diva-portal.org)
  • Integrated frameworks for assessing and managing health risks in the context of managed aquifer recharge with river water. (semanticscholar.org)
  • Exposure to biogas effluent represents an important health risk. (waterpathogens.org)
