Abstract

Oocysts of Cryptosporidium parvum were used to infect Madin-Darby bovine kidney cells. Cultures were incubated in a reduced-oxygen atmosphere in candle jars or in a 5% CO2-95% air atmosphere. At 72 h, parasites were quantitated microscopically and found to be enhanced 5.5-fold in the reduced-oxygen atmosphere. Using candle jars, we then determined that C. parvum was amenable to [3H]uracil incorporation assays and easily quantitated with this method.
