ABSTRACT
Cryptosporidium is an important enteric parasite and has been identi‘ed as the cause of numerous waterborne, foodborne, and day-care outbreaks of diarrheal disease worldwide [1]. The oocyst is the environmentally stable stage and is able to survive and penetrate routine wastewater treatment and is resistant to inactivation by commonly used drinking water disinfectants [2]. Currently, cryptosporidiosis represents the major public health concern of water utilities in developed nations [3] and has been responsible for 50.8% (165/325) of all water-associated outbreaks of parasitic protozoan disease reported in North American and Europe [4].
