Book Description
Waterborne transmission of disease has been documented throughout history. One of the greatest contributions to 20% century society has been the advent and application of water treatment technologies. However, analysis of current World Health Organization (WHO) estimates of illness and mortality and epidemiological investigations in the United States still indicates that the threat to public health from waterborne disease still exists There are a plethora of contaminants (both chemical and microbiological) that impose a direct risk to public health in the United States. The United States Environmental Protection Agency (EPA) reviews these contaminants and focuses its efforts upon the chemicals and microorganisms that are entered on the Contaminant Candidate List (CCL). Although it has never appeared on the CCL, a large amount of research during the 1990s was focused upon Cryptosporidium parvum, a pathogenic waterborne parasite, to fmd methods and techniques to measure, remove, and inactivate it in drinking water supplies. C. parvum gained national public attention in 1993 when cryptosporidiosis in Milwaukee, Wisconsin infected an estimated 403,000 people and killed an estimated 65 to 100 people (MacKenzie, et al., 1994).

Book Description
The chlorine dioxide inactivation of 'Cryptosporidium parvum' oocysts (Iowa isolate, genotype 2 (C)) was measured at bench scale in various water matrices using 'in vitro' excystation and a most probable number cell culture infectivity assay. 'In vitro' excystation underestimated inactivation compared to the infectivity assay. There was a significant difference (Ã = 0.05) in the inactivation of oocysts among the diverse water matrices measured by the infectivity assay but not by ' in vitro' excystation. A 'Ct' of 1000 mg·min/L was necessary for 2.0 log10 inactivation in type I deionised-distilled water adjusted to pH 8 at 22°C. This degree of resistance to chlorine dioxide by 'C. parvum' oocysts has not been quantified previously in the literature. 'Bacillus subtilis' spores (ATCC 19659) were found to be an unsuitable surrogate for 'C. parvum' oocysts in bench- and pilot-scale chlorine dioxide inactivation studies, but could function as a surrogate in pilot scale filtration removal studies.

Book Description
This new volume on Cryptosporidium and Cryptosporidiosis discusses all relevant aspects of the biology, molecular biology, host-parasite interaction, epidemiology as well as diagnosis and treatment of these widespread parasites. It represents a useful guide for physicians, microbiologists, veterinarians and water professionals seeking advanced knowledge and guidance about these important parasitic pathogens. A section on practical lab procedures discusses step-by-step guidelines for sample preparation and lab procedures. The new book may further serve as a reference work for graduate students in medical and veterinary microbiology.
