AIMS To assess the removal of viruses through the multiple steps of wastewater treatment in a full-scale municipal wastewater treatment plant in Alberta, Canada. METHODS AND RESULTS Samples were collected after each of the five treatment steps for a period of 16 months. The amount of viruses and their infectivity were analysed using real-time quantitative(More)
This study examined the distribution of antibiotic resistant Escherichia coli and E. coli O157 isolated from water, sediment and biofilms in an intensive agricultural watershed (Elk Creek, British Columbia) between 2005 and 2007. It also examined physical and chemical water parameters associated with antibiotic resistance. Broth microdilution techniques(More)
In vitro and animal studies report that some persistent organic pollutants (POPs) trigger the secretion of proinflammatory cytokines. Whether POP exposure is associated with a dysregulation of cytokine response remains to be investigated in humans. We studied the strength of association between plasma POP levels and circulating cytokines as immune(More)
Despite its relevance to public health, presence and concentrations of Campylobacter spp. in biofilms in natural aquatic environments has not been investigated. This study examined the occurrence of Campylobacter spp. in biofilms on a variety of surfaces (river rock, slate rock, wood, Lexan™, sandpaper, and sediment) and in water from December 2005 to(More)
Following the Earth Summit in 1992, Cuba designed and implemented a variety of programs, administrative structures, and public awareness activities to promote sound environmental management and sustainable development. This came shortly after the fall of the Soviet Union and the strengthening of the US blockade in 1990, which resulted in a 35% drop in Cuban(More)
Raw sewage ordinarily contains various biohazards (disease-causing organisms and their products), such as bacteria, viruses, fungi, helminths, and protozoa. Types, concentrations and survival of biohazards in sewage vary greatly depending on geographical and seasonal factors, and treatment levels within a wastewater treatment plant (WWTP). A review was(More)
Protecting the public from waterborne diseases is an environmental health responsibility that every government worldwide must deal with. Canada's recent experience with waterborne outbreaks has brought the effectiveness of its water-monitoring and treatment systems under scrutiny. This paper focuses on microbial waterborne diseases and the shortcomings of(More)
