Abstract

Cryptosporidium and Giardia are considered an emerging pathogens transmitted by water.These organisms are important under sanitary view due their resistance to conventional water treatment and environmental persistence. These microbial agents have been relevant role in sanitary quality of surface water and groundwater, recreational waters and reuse waters. The brazilian law, recognizing the impact of these organisms on health, determine investigation about Cryptosporidium and Giardia presence in drinking water.The proposal of this work is search these protozoans in drinking water samples before and after conventional treatment in a Drinking Water Plant from SABESP operation. The samples will be taken second USEPA-Method 1623,1999. This protocol consists of: Sample filtration and eluation, sample concentration and purification, sample staining and examination, and results report. (AU)
