Download or read book Exploring Different Components of Disease Transmission for Verocytotoxigenic Escherichia Coli VTEC Infections in Ontario Canada written by Roksolana Hovdey and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The transmission dynamics of human verocytotoxigenic Escherichia coli (VTEC) infections are not well understood. This thesis examines the transmission of VTEC, exploring the role of environmental conditions on the risk of primary infections, and the impact of person to person transmission during outbreaks. The first study explored the effect of environmental factors on VTEC infections in Ontario using case-crossover analyses. While the magnitude and direction of the effect was variable between health units, the findings demonstrate that infections were associated with hydrological conditions. The second study focused on the potential impact of person to person transmission using a mathematical model to describe an outbreak in Ontario. Based on the model results, including public health interventions targeting person-to-person transmission reduced the outbreak size by ~16%. The results from these studies demonstrate that watershed hydrology may be associated with VTEC infections, and that person to person transmission is an important transmission route to target for interventions during outbreaks.

Available in PDF, EPUB and Kindle. Book excerpt: Verocytotxin producing Escherichia coli (VTEC), and in particular, strains of serogroup o157, have emerged as significant pathogens causing a range of severe and potentially fatal illnesses. The European Union has recognised the threat posed by E. coli O157:H7 and the need to devise control strategies based on an understanding of VTEC pathogenicity, transmission, survival and growth. It also acknowledges the imortance of informing farmers, veterinarians, food producers and health authorities so that each of these groups can act appropriately to reduce the overall hazards posed by these organisms. To contribute to the development and dissemination of effect control strategies, the European Commission funded a Concerted Action Project "A European study on animal, food, and biomedical aspects of verocytotoxigenic E. coli including serotype O157:H7, an emerging pathogen" (CT98-3935) within the Agriculture and Agro-industry Framework IV Research Programme (1998-2001). This book, compiled under the auspices of the above project, integrates contributions from project participants and invited contributor, to provide a comprehensive overview of the current state of research on VTEC. It will be invaluable to current workers in this area, and those seeking an effective introduction to research on this important pathogen

Download or read book Animal Waste Water Quality and Human Health written by A. Dufour and published by IWA Publishing. This book was released on 2012-10-14 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Domestic animals contaminate recreational waters and drinking-water sources with excreta and pathogens; but this threat to public health is inadequately understood and is insufficiently addressed in regulations. More than 85% of the world’s faecal wastes is from domestic animals such as poultry, cattle, sheep and pigs. These animals harbor zoonotic pathogens that are transported in the environment by water, especially runoff. However little information exists on health effects associated with exposure to this potential hazard to human health; and water standards focused on control of human fecal contamination do reflect the contribution of non-human fecal contamination to risk. Does compliance with current monitoring practices using microbial indicators provide protection against animal and bird sources of fecal contamination? Prepared with contributions from a group of international experts, Animal Waste, Water Quality and Human Health considers microbial contamination from domestic animal and bird sources and explores the health hazards associated with this microbial contamination and approaches to protecting public health. Animal Waste, Water Quality and Human Health will be of interest to regulators with responsibility for recreational waters, drinking water quality and water reuse; policymakers working in water quality, public health and agriculture; decision makers responsible for livestock management; and scientists and practitioners concerned with many affected subjects. Topics covered include: Credible waterborne zoonotic pathogens are discussed and ranked according to their potential hazard level. Each pathogen is described with regard to their sources, reservoirs, and infectivity. Faecal production rates of various domestic animals are discussed, alongside pathogen transmission in animal populations, pathogen prevalence in animals and “supershedders”. Transport of fecal indicator organisms and their episodic occurrence in catchments. Interventions for improving food safety and reducing production losses. The impact of interventions, e.g. enhanced attenuation and storage to prevent spills; benchmarking against best management practices to reduce diffuse source contamination. Models to inform design of farm-scale best management practices and the effectiveness of best management practices for attenuating pathogen transport within catchments. The complex nature of human exposure to zoonotic waterborne pathogens; including the relationships among livestock waste contamination, water impairment, zoonotic pathogens, and human infection and illness. Human exposure interventions include case studies that discuss eradicating disease in discharging populations, adding filtration to minimal treated water to reduce Cryptosporidium occurrence and UV disinfection of beach waters to reduce beach postings. Indicators, sanitary surveys and source attribution techniques; risk assessment of exposure to zoonotic pathogens, including an interactive risk comparison approach. A review of epidemiological studies that address the relationship between swimmer illness and exposure to waters contaminated by nonhuman fecal wastes. Economic evaluation of the costs and benefits associated with animal waste management and human health.
