Solar water disinfection (SODIS) is a simple method that involves the use of solar radiation to destroy pathogenic microorganisms that cause waterborne diseases. A notable increase in water temperature and the existence of a large number of empty or partially excysted (i.e. unviable) oocysts have been observed in previous SODIS studies with water experimentally contaminated with<jats:italic>Cryptosporidium parvum<\/jats:italic>oocysts under field conditions. The aim of the present study was to evaluate the effect of the temperatures that can be reached during exposure of water samples to natural sunlight (37\u201350\u00b0C), on the excystation of<jats:italic>C. parvum<\/jats:italic>in the absence of other stimuli. In samples exposed to 40\u201348\u00b0C, a gradual increase in the percentage of excystation was observed as the time of exposure increased and a maximum of 53\u00b781% of excystation was obtained on exposure of the water to a temperature of 46\u00b0C for 12 h (<jats:italic>versus<\/jats:italic>8\u00b780% initial isolate). Under such conditions, the oocyst infectivity evaluated in a neonatal murine model decreased statistically with respect to the initial isolate (19\u00b738%<jats:italic>versus<\/jats:italic>100%). The results demonstrate the important effect of the temperature on the excystation of<jats:italic>C. parvum<\/jats:italic>and therefore on its viability and infectivity.<\/jats:p>","DOI":"10.1017\/s0031182009005563","type":"journal-article","created":{"date-parts":[[2009,2,7]],"date-time":"2009-02-07T06:44:12Z","timestamp":1233989052000},"page":"393-399","source":"Crossref","is-referenced-by-count":15,"title":["Excystation
