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.

Download or read book Comparing Cell Culture and Mouse Assays for Measuring Infectivity of Cryptosporidium written by Paul A. Rochelle and published by IWA Publishing. This book was released on 2005-06-30 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell culture techniques are routinely used for measuring the infectivity of a wide range of human pathogens. A variety of different cell culture systems and detection methodologies have been applied to Cryptosporidium parvum. However, the correlation between cell culture methods and animal infectivity assays has not been thoroughly investigated. Although many cell culture methods have been developed for C. parvum, it has not been proven that infectivity in cell culture is a good indicator of the ability of oocysts to cause infections in animals. The objective of this research was to compare in-vitro cell culture methods with a mouse assay for measuring infectivity of C. parvum oocysts. The specific objectives were to (1) compare the dose response and sensitivity of cell culture and mouse assays with multiple isolates; (2) compare infectivity methods with oocysts exposed to environmental water samples; (3) determine the reproducibility and variability of the methods; and (4) compare cell culture and animal assays for assessing ozone and UV disinfection.For untreated oocysts, challenge doses were enumerated by flow cytometry. Dose response curves were constructed by regression analysis of oocyst dose against a logistic transformation of the proportional infectivity and the 50% infectious doses for each isolate were calculated by solving the regression for a logit value of zero. Infections in CD-1 mice were detected by microscopy following staining with hematoxylin and eosin. Infection in HCT-8 and Caco-2 cells was detected by C. parvum-specific RT-PCR. In MDCK cells, infection was detected using immunofluorescence. For disinfection studies, oocysts were exposed to UV using a medium-pressure, collimated beam apparatus and inactivation was measured as the difference in ID50 of unexposed and UV-exposed oocysts. Oocysts were exposed to ozone using batch, semi-batch, and single continuously stirred tank reactors at 1, 5, and 15°C.This investigation demonstrated that in-vitro cell culture was equivalent with a mouse assay for measuring infectivity of untreated C. parvum oocysts and should therefore be considered a practical alternative for assessing the potential of oocysts to cause infection. However, the high levels of variability displayed by mouse and cell culture methods indicated that infectivity and disinfection experiments should be limited to discerning relatively large differences. Of the three cell culture assays, the HCT-8/RT-PCR method displayed the closest agreement with the CD-1 mouse assay. C. hominis was infectious in HCT-8 cells but did not infect mice. Similar results were obtained with CD-1 mice and HCT-8 cells for measuring infectivity of oocysts that had been exposed to environmental water for 35 days. There was also very good agreement between HCT-8 cell culture and CD-1 mouse assays for measuring UV inactivation of C. parvum. A medium-pressure UV dosage of 5.6 mJ/cm2 resulted in 2-log10 inactivation. The shapes of ozone inactivation curves were generally the same for mouse and cell culture derived data although the CD-1 mouse assay typically generated 0.5 to 1-log10 higher levels of inactivation than HCT-8 cells. In addition, there was a stimulatory response in oocysts exposed to ozone below 20 mg.min/L when assayed by HCT-8 cell culture. Consequently, further research is necessary to understand the response of oocysts to ozone when inactivation is assessed by cell culture methods. The water industry should adopt in-vitro cell culture as a routine method for measuring the infectivity of waterborne C. parvum and C. hominis oocysts. This project has demonstrated that cell culture has equivalency with the standard CD-1 mouse assay and cell culture assays can be applied to oocysts recovered from water using approved methods. However, there needs to be a thorough, robust, and well-controlled study to compare the various cell culture-based assays for measuring C. parvum and C. hominis infectivity. This evaluation should include inter-laboratory comparisons and round-robin testing. Cell culture-based assays should also be used to assess disinfection of C. hominis isolates.

This book was released on 2008 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surveillance for waterborne disease and outbreaks associated with drinking water and water not intended for drinking-- United States, 2005-2006: "Problem/Condition: Since 1971, CDC, the U.S. Environmental Protection Agency (EPA), and the Council of State and Territorial Epidemiologists have maintained a collaborative Waterborne Disease and Outbreak Surveillance System (WBDOSS) for collecting and reporting data related to occurrences and causes of waterborne-disease outbreaks (WBDOs) and cases of waterborne disease. This surveillance system is the primary source of data concerning the scope and effects of waterborne disease in the United States. Reporting Period: Data presented summarize 28 WBDOs that occurred during January 2005-December 2006 and four previously unreported WBDOs that occurred during 1979-2002. Description of System: The surveillance system includes data on WBDOs associated with recreational water, drinking water, water not intended for drinking (WNID) (excluding recreational water), and water use of unknown intent. Public health departments in the states, territories, localities, and Freely Associated States (FAS) (i.e., the Republic of the Marshall Islands, the Federated States of Micronesia, and the Republic of Palau, formerly parts of the U.S.-administered Trust Territory of the Pacific Islands) are primarily responsible for detecting and investigating WBDOs and voluntarily reporting them to CDC by a standard form. Only cases and outbreaks associated with drinking water, WNID (excluding recreational water), and water of unknown intent (WUI) are summarized in this report. Cases and outbreaks associated with recreational water are reported in a separate Surveillance Summary."--Page 39

Available in PDF, EPUB and Kindle. Book excerpt: The main goal in compiling this book was to highlight the situation in Africa in terms of AIDS and opportunistic diseases. Several chapters reveal great poverty, an apocalyptic situation in many parts of Africa. Global migration of people resulted in their exposure to pathogens from all over the world. This fact has to be acknowledged and accepted as African reality. New, unconventional hypotheses, not determined by established dogmas, have been incorporated into the book, although they have not yet been sufficiently validated experimentally. It still applies that any dogma in any area of science, and medicine in particular, has and always will hinder progress. According to some biologists, in the future, AIDS is very likely to occur in a number of variations, as a direct result of the ongoing processes in the global human society. Thus, we urgently need a comprehensive solution for AIDS, in order to be ready to fight other, much more dangerous intruders.

Download or read book Handbook of Animal Models of Infection written by Merle A. Sande and published by Academic Press. This book was released on 1999-05-28 with total page 1136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Animal Models of Infection is a complete revision of a three-volume text that was published in 1986. It incorporates the major advances in the field during the past decade, in particular those concerning molecular biological procedures and new models that have been developed. It focuses on both methods and techniques, which makes it an essential and comprehensive reference as well as a benchtop manual. The Handbook will help investigators save time and effort in formulating an approach to test a new potential therapeutic agent or combination of agents for in vivo efficacy and to position the therapy for specific infections where it may have therapeutic promise. The book is divided into five sections; the first covering the general methodologies, followed by sections describing experimental bacterial, mycotic, parasitic, and viral infections. Discusses ethical and safety aspects in an introductory background section Covers principles of animal care and current techniques appropriate for the use of animal models of infection Details a wide range of animals including rodents, rabbits, cats, and primates Provides hands-on descriptions of how to set up the model Discusses the major advantages and limitations of each model Ensures full coverage of bacterial, fungal, viral, and parasitic infections
