Effects of Ozone and Storage Temperature on Giardia Cysts
The effects of ozone and storage temperature on the survival of Giardia lamblia cysts, the cause of human giardiasis, and Giardia muris, a parasite of mice, were compared. The viabilities of the cysts were similar over a period of 25 days of storage in the range of ‐6° to 37°C; the optimum temperature for their long‐term survival was determined to be about 5°C. Ozone was extremely effective for inactivating cysts of both Giardia species, with G. muris being consistently more resistant than G. lamblia at pH 7 and 5°C and 25°C.
