Download or read book Recovery of Cryptosporidium Oocysts from High volume Water Samples written by J. Clancy and published by International Water Assn. This book was released on 2004 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is of importance to the water industry because there is great interest among water utilities, regulators, and consumers about the occurrence of Cryptosporidium oocysts in water supplies. The methodologies available for recovery and detection of the parasite had been improved over the years, but the methods focused on collection and analysis of relatively low sample volumes of source water; there was no usable finished drinking water method. This project improved upon the existing methods for oocyst analysis of water permitting larger volumes of source water to be collected and analyzed, and developed a method for 1000 L finished drinking water samples. All methods developed in the project were validated usihg the criteria specified by the USEPA, so that the methods can be used for compliance monitoring. These new methods are now in widespread use in the U.S. and in other countries.
Download or read book Cryptosporidium written by Mark S Smith and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cryptosporidium, in its various forms, is a widely recognised cause of outbreaks of waterborne disease. Regulatory bodies worldwide are increasingly requiring the development of "fit-for-purpose" detection methods for this protozoan parasite, but analysis is often problematic. Bringing together international academic and industry-based experts, this book provides a comprehensive review of the current state of analytical techniques for the detection of Cryptosporidium, as well as looking at likely future developments. In particular, the issues of species identification and oocyst viability are addressed. Quality assurance issues and potential problems associated with the new Cryptosporidium regulations are also highlighted. The extent of the perceived problems and the regulatory backdrop against which the analysis must be carried out are also discussed. Scientists in the water industry, environmental testing laboratories, researchers, consultants, environmental health professionals, food manufacturers and regulatory or environmental bodies are amongst the many who should read this book. In addition, anyone with an interest in microbiological challenges and problem-solving will welcome the coverage.

Download or read book Cryptosporidium From Molecules to Disease written by R.C.A. Thompson and published by Elsevier. This book was released on 2003-12-17 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the relatively short period since Cryptosporidium was recognised as a human pathogen, and that it could be transmitted in water as well as directly between animals and people, it has been the subject of intense investigations. Its status as an opportunistic pathogen, especially in AIDS patients, and the lack of effective anti-cryptosporidial drugs have served to emphasise the public health importance of this organism. This has to some extent overshadowed the fact that Cryptosporidium is also an important pathogen of domestic animals and wildlife. In recent years, the application of molecular biology and culture techniques have had an enormous impact on our understanding of the aetiological agents of cryptosporidial infections and our ability to study the causative agents in the laboratory. As a consequence, a wealth of information and novel data has been produced during the last 3-4 years, particularly in the areas of taxonomy, biology, pathogenesis, epidemiology - particularly zoonotic and water borne transmission, and treatment.It is thus very timely to bring together in this book the international research community involved to review the major advances in research and identify the important research priorities for the future, thus enabling as wide an audience as possible to benefit from and share in this comprehensive look at Cryptosporidium and cryptosporidiosis.

Available in PDF, EPUB and Kindle. Book excerpt: Public Health Microbiology: Methods and Protocols is focused on microorganisms that can present a hazard to human health in the course of everyday life. There are chapters dealing with organisms that are directly pathogenic to humans, including bacteria, viruses, and fungi; on organisms that produce toxins during growth in their natural habitats; on the use of bacteriocins produced by such organisms as lactobacilli and bifidobacteria; as well as several chapters on hazard analysis, the use of disinfectants, microbiological analysis of cosmetics, and microbiological tests for sanitation equipment in food factories. Additional chapters look at the use of animals (mice) in the study of the various characteristics of milk and their relationships with lactic acid bacteria in particular. Other chapters focus on special methods for determining particular components of milk. In particular, in Parts I and II, on bacterial and viral pathogens, special attention is given to methods for PCR detection of genes with resistance to tetracycline, as well as to Salmonella enterica; for identification and typing of Campylobacter coli; for detection of the abundance of enteric viruses, hepatitis A virus, and rotaviruses in sewage, and of bacteriophages infecting the O157:H7 strain of Escherichia coli. Part III offers methods for computerized analysis and typing of fungal isolates, for isolation and enumeration of fungi in foods, and for the determination of aflatoxin and zearalenone.
Download or read book Global Issues in Water Sanitation and Health written by Institute of Medicine and published by National Academies Press. This book was released on 2009-10-25 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the human population grows-tripling in the past century while, simultaneously, quadrupling its demand for water-Earth's finite freshwater supplies are increasingly strained, and also increasingly contaminated by domestic, agricultural, and industrial wastes. Today, approximately one-third of the world's population lives in areas with scarce water resources. Nearly one billion people currently lack access to an adequate water supply, and more than twice as many lack access to basic sanitation services. It is projected that by 2025 water scarcity will affect nearly two-thirds of all people on the planet. Recognizing that water availability, water quality, and sanitation are fundamental issues underlying infectious disease emergence and spread, the Institute of Medicine held a two-day public workshop, summarized in this volume. Through invited presentations and discussions, participants explored global and local connections between water, sanitation, and health; the spectrum of water-related disease transmission processes as they inform intervention design; lessons learned from water-related disease outbreaks; vulnerabilities in water and sanitation infrastructure in both industrialized and developing countries; and opportunities to improve water and sanitation infrastructure so as to reduce the risk of water-related infectious disease.
