Abstract
This study was designed to establish the time frame of viability and infectivity of Cryptosporidium, when the Cryptosporidium is discharged to the aquatic environment. Changes in viability and infectivity of Cryptosporidium in relation to temperature and pH were investigated during winter (Dec 05-Feb 06) using semipermeable cellulose tubes containing infective Cryptosporidium. Infectivity was maintained at 50% after 30 days and almost completely lost after 50 days. It was also established that viability was maintained at about 8% after 90 days.
