Cryptosporidium and Giardia fact sheet now available!

Cryptosporidium spp. and Giardia duodenalis are the most prevalent waterborne parasitic alveolates that can cause a gastrointestinal illness that involves watery diarrhea and can interfere with the body’s natural absorption of nutrients, therefore presenting a major public health concern for water utilities in developed nations. The Oo/cyst is a hardy thick-walled stage of the life cycles of these parasites and are highly-resistant to environmental stresses and disinfection treatments (including chlorine treatment of community water supplies). Humans, wildlife and domestic livestock all potentially contribute Cryptosporidium and Giardia to surface waters, and thus, this research looks at the potential role that these host species play in the dissemination of Cryptosporidium and Giardia to drinking water sources and the associated public health risks.
