Sedimentation of Free and AttachedCryptosporidium Oocysts and Giardia Cysts in Water
The theoretically calculated sedimentation kinetics showed a good agreement with the experimentally observed kinetics, and sedimentation of attached (oo)cysts after discharge into surface water will probably be a significant factor in the environmental ecology ofC. Expand
Monitoring of Waterborne Pathogens in Surface Waters in Amsterdam, The Netherlands, and the Potential Health Risk Associated with Exposure to Cryptosporidium and Giardia in These Waters
ABSTRACT The water in the canals and some recreational lakes in Amsterdam is microbiologically contaminated through the discharge of raw sewage from houseboats, sewage effluent, and dog and birdExpand
Survival of Cryptosporidium parvum, Escherichia coli, faecal enterococci and Clostridium perfringens in river water : Influence of temperature and autochthonous microorganisms
The aim of this study was to determine the rate at which C parvum oocysts, E coli , faecal enterococci and C perfringens spores die in surface water and the influence of temperature and the presence of autochthonous (micro)organisms on the die-off rate. Expand
Multidrug-Resistant and Extended Spectrum Beta-Lactamase-Producing Escherichia coli in Dutch Surface Water and Wastewater
The data show that MDR E. coli are omnipresent in Dutch surface water, and indicate that municipal wastewater significantly contributes to this occurrence. Expand
Rainwater harvesting: quality assessment and utilization in The Netherlands.
This three-year study demonstrated that rainwater stored in different reservoirs in The Netherlands was frequently faecally contaminated and incidentally contained potential human pathogens such as Campylobacter, Cryptosporidium, Giardia, Aeromonas hydrophila and Legionella. Expand
Exposure assessment for swimmers in bathing waters and swimming pools.
QMRA for Cryptosporidium and Giardia was demonstrated based on data from previous studies on the occurrence of these pathogens in recreational lakes and a swimming pool, and previous assumptions on swimmer exposure were replaced with estimates of exposure parameters. Expand
Quantitative assessment of infection risk from exposure to waterborne pathogens in urban floodwater.
Risks of infection from exposure to urban floodwater were assessed using quantitative microbial risk assessment (QMRA) and it was found that annual infection risks will increase with a higher frequency of urban flooding due to heavy rainfall as foreseen in climate change projections. Expand
Escherichia coli O157:H7 in drinking water from private water supplies in the Netherlands.
The results indicate that compliance with microbiological quality standards obtained in routine monitoring does not always guarantee the absence of pathogens. Expand
Cryptosporidium and Giardia in commercial and non-commercial oysters (Crassostrea gigas) and water from the Oosterschelde, The Netherlands.
The data suggest that consumption of raw oysters from the Oosterschelde may occasionally lead to cases of gastro-intestinal illness and the detection of Cryptosporidium and Giardia in oysters destined for human consumption has implications for public health only when human pathogenic (oo)cysts that have preserved infectivity during their stay in a marine environment are present.

Distribution, Numbers, and Diversity of ESBL-Producing E. coli in the Poultry Farm Environment
The introduction of ESBL-producing E. coli from poultry farms to the environment may pose a health risk if these bacteria reach places where people may become exposed. Expand
