Cryptosporidium oocyst inactivation rates for reagent-grade MilliQ water (MQH20), Hope Valley raw water (HV raw), and Hope Valley autoclaved water (HV autoclaved) at four temperatures: 4, 15, 20, and 25°C. Experiments were performed in triplicate for all three water types. Infectivity was calculated using the cell culture-TaqMan PCR assay. Oocysts were applied to cell monolayers in triplicate for each sampling point. Error bars indicate standard deviations.
