Microbiology Of Waterborne Diseases

The second edition of Microbiology of Waterborne Diseases describes the diseases associated with water, their causative agents and the ways in which they gain access to water systems. The book is divided into sections covering bacteria, protozoa, and viruses. Other sections detail methods for detecting and identifying waterborne microorganisms, and the ways in which they are removed from water, including chlorine, ozone, and ultraviolet disinfection. The second edition of this handbook has been updated with information on biofilms and antimicrobial resistance. The impact of global warming and climate change phenomena on waterborne illnesses are also discussed. This book serves as an indispensable reference for public health microbiologists, water utility scientists, research water pollution microbiologists environmental health officers, consultants in communicable disease control and microbial water pollution students. Focuses on the microorganisms of most significance to public health, including E. coli, cryptosporidium, and enterovirus Highlights the basic microbiology, clinical features, survival in the environment, and gives a risk assessment for each pathogen Contains new material on antimicrobial resistance and biofilms Covers drinking water and both marine and freshwater recreational bathing waters

Water borne disease is responsible for millions of deaths worldwide every year. Within both developed and developing countries the demand for clean drinking and bathing water is ever increasing and the control of water borne disease is therefore of extreme importance. The book first addresses the magnitude of the problem, with subsequent chapters on specific diseases including Crytosporidiosis, Schistosomiasis, legionellosis and viral gastrointeritis. Concluding chapters discuss practical control issues such as basic water treatment and the problems of water borne disease control in less developed countries.

Recent and forecasted advances in microbiology, molecular biology, and analytical chemistry have made it timely to reassess the current paradigm of relying predominantly or exclusively on traditional bacterial indicators for all types of waterborne pathogens. Nonetheless, indicator approaches will still be required for the foreseeable future because it is not practical or feasible to monitor for the complete spectrum of microorganisms that may occur in water, and many known pathogens are difficult to detect directly and reliably in water samples. This comprehensive report recommends the development and use of a "tool box" approach by the U.S Environmental Protection Agency and others for assessing microbial water quality in which available indicator organisms (and/or pathogens in some cases) and detection method(s) are matched to the requirements of a particular application. The report further recommends the use of a phased, three-level monitoring framework to support the selection of indicators and indicator approaches.Â

Written by a team of international experts, this third edition designed to guide public health personnel or teams in any country that investigates reports of alleged waterborne illnesses. The manual is based on epidemiologic principles and investigative techniques that have been found effective in determining causal factors of disease incidence. The guidelines are presented in the sequence usually followed during investigations and are organized so that an investigator can easily find the information needed in any phase of an investigation. The book services as a guide to: • Develop a waterborne disease surveillance and emergency operations program • Handle illness alerts and water-related complaints that may be related to illness • Interview ill persons, those at risk, and controls • Develop a case definition • Transport water specimens and clinical specimens • Trace sources of contamination • Identify factors responsible for contamination, survival of pathogenic microorganisms or toxic substances, and/or propagation of pathogens • Collate and interpret collected data • Report information about the outbreak This edition has been extensively updated. A section has been added on water not intended for drinking as a source of illness. The chapter on “collection and analysis of data” has been significantly expanded to explain how data is collected and used to suggest possible vehicles, routes, and agents. The book is designed to improve the quality of investigation of outbreaks and disease surveillance.

The microbiology of drinking water remains an important worldwide concern despite modem progress in science and engineering. Countries that are more technologically advanced have experienced a significant reduction in water borne morbidity within the last 100 years: This reduction has been achieved through the application of effective technologies for the treatment, disinfec tion, and distribution of potable water. However, morbidity resulting from the ingestion of contaminated water persists globally, and the available ep idemiological evidence (Waterborne Diseases in the United States, G. F. Craun, ed. , 1986, CRC Press) demonstrates a dramatic increase in the number of waterborne outbreaks and individual cases within the United States since the mid-1960s. In addition, it should also be noted that the incidence of water borne outbreaks of unknown etiology and those caused by "new" pathogens, such as Campylobaeter sp. , is also increasing in the United States. Although it might be debated whether these increases are real or an artifact resulting from more efficient reporting, it is clear that waterborne morbidity cannot be ignored in the industrialized world. More significantly, it represents one of the most important causes of illness within developing countries. Approxi mately one-half the world's population experiences diseases that are the direct consequence of drinking polluted water. Such illnesses are the primary cause of infant mortality in many Third World countries.

In the developed world, the connection between water, hygiene and health is taken for granted. However, for the less fortunate majority, access to potable water is non-existent and remains a daily struggle. Bacteria, viruses and parasites in contaminated water cause water borne disease. Of concern are the so-called new emerging pathogens, contributing to water borne disease, one of the biggest human tragedies, killing more than 5 million people each year. About 2.3 billion people suffer from diseases linked to contaminated water and some 6,000 people die daily as a result of this. Some 60% of all infant mortality worldwide is linked to water-related infectious and parasitic diseases. Treating water before use can eliminate most of these waterborne pathogens. The essential starting point is knowledge of the disease-causing organisms, the detection techniques, and the epidemiology, which is the focus of this book. Microbial Waterborne Pathogens provides up-to-date coverage of waterborne microbial pathogens including traditional and emerging pathogens and the latest molecular detection techniques. The link between climate and disease is covered in the book and indicates future approaches to dealing with this important area as we face the effects of global climate change All the existing and emerging pathogens including bacteria, viruses and protozoa are reviewed. The characteristics of each organism are discussed in detail as well as their epidemiology. Methods for the detection of these pathogens, traditional and new are presented. Microbial Waterborne Pathogens provides students, academics and practitioners with a complete reference book on the microbiological quality and safety of potable water.

Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.
