Waterborne transmission of Giardia and Cryptosporidium.
Giardia and Cryptosporidium spp. are parasitic protozoa which are frequent etiologic agents of waterborne diseases. This lecture will summarize the main biological and environmental factors involved in the potential risk for waterborne transmission of giardiosis and cryptosporidiosis, which have caused many outbreaks in different geographical areas. In particular, the current epidemiological situation of these parasitoses in Italy will be analysed, on the basis of research carried out on humans and on the environment. Finally, current methods for evaluating the presence of Giardia cysts and Cryptosporidium oocysts in water and new methods for cyst/oocyst removal from drinking water and wastewater will be examined.
