Book Synopsis Zoonoses - Infections Affecting Humans and Animals by : Andreas Sing
Download or read book Zoonoses - Infections Affecting Humans and Animals written by Andreas Sing and published by Springer. This book was released on 2014-12-08 with total page 1127 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book will cover the most important zoonoses with a public health impact and debate actual developments in this field from a One Health perspective. The outline of the book follows a “setting” approach, i.e. special settings of zoonoses with a public health aspect, rather than presenting a simple textbook of an encyclopedic character. Main chapters will deal with zoonoses in the food chain including a special focus on the emerging issue of antibiotic resistance, with zoonoses in domestic and pet animals, in wildlife animal species (including bats as an important infectious agent multiplier), influenza and tuberculosis as most prominent zoonoses, and zoonotic pathogens as bioterroristic agents. Special interest chapters debate non-resolved and currently hotly debated zoonoses (e.g. M. Crohn/paratuberculosis, chronic botulism) as well as the economic and ecological aspects of zoonoses.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cryptosporidium and Giardia are important disease agents for both humans and animals worldwide. Unlike many pathogens, their capacity for surviving in soil and water for extended periods of time enables environmental transmission. Both parasites replicate within warm-blooded vertebrate hosts and are excreted as an environmentally resistant oocyst or cyst, respectively. New hosts become infected through ingestion of oocysts or cysts in contaminated water, food, or soil. The objective of this thesis work was to utilize an epidemiologic approach to identify environmental factors associated with the prevalence of Cryptosporidium and Giardia spp. in California coastal wetlands, as well as to ascertain the prevalence and identify potential transmission pathways within the animal community in the Virunga Massif, Rwanda. Because Cryptosporidium and Giardia are waterborne parasites, key factors in wetland ecology were examined for their impact on parasite levels in water. First, concentrations of these parasites within three coastal California wetlands were determined. Proximity to livestock operations and recent rainfall events were associated with increased pathogen levels. Second, experimental models mimicking wetland characteristics were used to isolate the effects of several parameters. Vertical settling columns identified increased salinity as leading to slower settling of Giardia and horizontal flow mesocosm tanks identified increased salinity as leading to slower removal of Cryptosporidium. Furthermore, presence of vegetation led to enhanced removal of Cryptosporidium oocysts, Giardia cysts, and Toxoplasma gondii surrogates from surface water in the mesocosm tanks. The impact of Cryptosporidium and Giardia on animal health is important not only because many wildlife species are suspected to be reservoirs of these parasites for humans, but also because the effect of infection with these parasites on health is of concern in vulnerable wildlife species. To assess the impact of these parasites on mountain gorillas (Gorilla beringei beringei), a critically endangered primate restricted to two forests located in Rwanda, Democratic Republic of Congo and Uganda, an investigation was conducted comparing protozoal prevalence and strain identity in mountain gorillas, domestic cattle, and forest buffalo (Syncerus caffer nanus). Giardia was found in all three species, and genotyping results identified genotypic assemblage B in the gorilla samples and assemblage E in the cattle samples. While this study did not confirm a transmission pathway between cattle and gorillas using the forest buffalo as an intermediary, it suggests that future work should also evaluate humans as potentially contributing to fecal pathogen contamination within the forest. Environmentally transmitted protozoa are of global health concern due to their extended survival outside of a host, coupled with the relative difficulty and expense of detection in environmental samples. The drivers for protozoal disease transmission, as detailed in Chapter 1, emphasize the key role that environmental change has on Giardia and Cryptosporidium. Some of these changes are evaluated in Chapters 2 and 3, which highlight research conducted on protozoal transport through coastal wetlands. Health impacts of these protozoa on wildlife and livestock cannot be discounted, and Chapter 4 surveys the presence of Cryptosporidium and Giardia in a complex wildlife community in Rwanda.

Available in PDF, EPUB and Kindle. Book excerpt: Giardia lamblia has been problematic in British Columbia (BC) since the 1980s, having been the etiological agent in 13 of the 29 documented waterborne outbreaks in the province. Despite improvements to drinking water facilities, giardiasis continues to occur at higher rates in BC compared to the rest of Canada. This study aimed to address knowledge gaps with regard to the occurrence and molecular epidemiology of Giardia isolates, to help address the higher occurrence of giardiasis in British Columbia. This study was conducted in three steps. First, tools were developed and validated to genotype G.lamblia isolates into groups/genotypes called Assemblages. These tools were first applied to a library of archived G.lamblia isolates collected from patients, animals and water sources in British Columbia. These same tools were then applied to water samples collected in the Salmon River watershed in the Township of Langley, BC, the second stage of the study. The occurrence and characteristics of isolates collected in the Salmon River were then compared to isolates collected in the Grand River watershed, an intensely developed mixed-urban watershed in Ontario, for the third stage of the study. In the first study, it was determined that 18s rRNA nested PCR with sequencing was the most appropriate molecular epidemiological tools to study G.lamblia in water supplies. Using a combination of molecular methods and USEPA Method 1623, it was determined that the majority of isolates in the Salmon River watershed were potentially infectious to humans (belonging to Assemblages A and B), with Assemblage A occurring most frequently. In contrast, Assemblage B was the most frequently detected genotype in the Grand River watershed, a more intensely developed watershed. Analysis of rainfall and sequence data suggests that G.lamblia isolates could have originated from sewage effluent or septic tanks, which was confirmed with the occurrence of Cryptosporidium hominis. Non-zoonotic G.lamblia is.
Book Synopsis Watershed Management for Potable Water Supply by : National Research Council
Download or read book Watershed Management for Potable Water Supply written by National Research Council and published by National Academies Press. This book was released on 2000-02-17 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1997, New York City adopted a mammoth watershed agreement to protect its drinking water and avoid filtration of its large upstate surface water supply. Shortly thereafter, the NRC began an analysis of the agreement's scientific validity. The resulting book finds New York City's watershed agreement to be a good template for proactive watershed management that, if properly implemented, will maintain high water quality. However, it cautions that the agreement is not a guarantee of permanent filtration avoidance because of changing regulations, uncertainties regarding pollution sources, advances in treatment technologies, and natural variations in watershed conditions. The book recommends that New York City place its highest priority on pathogenic microorganisms in the watershed and direct its resources toward improving methods for detecting pathogens, understanding pathogen transport and fate, and demonstrating that best management practices will remove pathogens. Other recommendations, which are broadly applicable to surface water supplies across the country, target buffer zones, stormwater management, water quality monitoring, and effluent trading.
