Low-pressure UV inactivation and DNA repair potential of Cryptosporidium parvum oocysts
Article Abstract:
Monchromatic, low-pressure UV radiation can inactivate Cryptosporidium oocysts and the oocysts do not seem to be capable of repairing the CNA damage. Cryptosporidium is resistant to other forms of disinfection, including chemical disinfection.

Reduction of Norwalk virus, poliovirus 1, and bacteriophage MS2 by ozone disinfection of water
Article Abstract:
Results indicate that rapid and extensive reduction of Norwalk and other enteric viruses can be achieved by ozone disinfection of water. Data show more than 3 log(sub)10 reduction in Norwalk, poliovirus 1, and bacteriophage MS2 within 10 seconds of ozone treatment.

Inactivation of Cryptosporidium parvum oocysts and Clostridium perfringens spores by a mixed-oxidant disinfectant and by free chlorine
Article Abstract:
An alternative disinfection system composed of an electrochemically produced mixed-oxidant solution was examined for inactivation of both Cryptosporidium parvum oocysts and Clostridium perfringens spores. The disinfection efficacy of the mixed-oxidant solution was compared to that of free chlorine. Findings showed that the mixed-oxidant solution was considerably more effective than free chlorine in inactivating both microorganisms. Free chlorine produced no quantifiable inactivation of C. parvum oocysts and C. perfringens spores.
