AIMS To determine the effect of solar radiation on Cryptosporidium parvum in tap and environmental waters. METHODS AND RESULTS Outdoor tank experiments and a cell culture infectivity assay were used to measure solar inactivation of C. parvum oocysts in different waters. Experiments conducted on days with different levels of solar insolation identified rapid inactivation of oocysts in tap water (up to 90% inactivation within the first hour). Increased dissolved organic carbon content in… CONTINUE READING
