Effects of environmental conditions and standard chlorination practices on the infectivity of Giardia cysts



Effects of environmental conditions and standard chlorination practices on the infectivity of Giardia cysts



Diseases of Aquatic Organisms, 21: 1-5



Effects of environmental conditions and standard chlorination practices on Giardia muris cysts were examined using infectivity of cysts to mice as a biological indicator. The eosin exclusion assay consistently indicated high levels of cyst viability, despite their total loss of infectivity. Storage of cysts at 4 degrees C in dry faecal pellets, or soaked in saline, reduced the infectivity of cysts markedly after 3 days.
