| As human population increases worldwide, water quality will become increasingly problematic, and food consumed raw may be of higher risk. This is already evident for oysters grown in coastal areas - despite regulations based on bacterial indicators, oysters are still implicated in food-borne outbreaks worldwide. The pathogens most frequently detected are human noroviruses, which are shed at high concentrations in human excreta and are very resistant to environmental conditions. Sewage treatment plants usually apply a variety of steps such as activated sludge treatment, chlorine or UV disinfection to eliminate contaminants, these processes have variable efficacy. This study demonstrates the impact of replacing an old lagoon-based sewage treatment plant with... |

| La station d'assainissement de Dabou (Côte d'Ivoire), constituée de trois bassins de lagunage, est conçue pour assurer une épuration biologique des effluents domestiques et une valorisation des sous-produits terminaux par l'aquaculture. Le premier bassin, caractérisé par une fosse anaérobie, est suivi de deux bassins similaires temporairement aérobies, disposés en série. Pour comprendre le fonctionnement écologiques et les performances de cette station, une opération a été menée en février 1989. Outre la description des variations nycthémérales des paramètres physiques et l'estimation de la charge organique, le cycle biogéochimique de l'azote et les compartiments bactériens, phytoplanctoniques et zooplanctoniques ont été étudiés pour chacun des bassins.Le... |

| The aim of this study was to verify the presence and annual distribution of adenoviruses and hepatitis A virus in domestic sewage in the city of Limeira, São Paulo. Fifty samples with a volume of 8 liters each were collected weekly from December 2004 to December 2005. The viruses were concentrated by filtration through positively charged ZP60S filter membranes, followed by ultracentrifugation. Human adenoviruses (HAdV) were detected by PCR followed by nested-PCR and screening for species F was done by restriction of the PCR product with TaqI endonuclease. Virus infectivity assays were performed by inoculation of concentrates onto HEp-2 cell monolayers. RT-PCR was used for the detection of hepatitis A virus. HAdV were detected in all samples, and 64% of... |
