RESUMO
A dose of 5.0x106 Cryptosporidium parvum oocysts was inoculated in a newborn calf. After the inoculation, the feces were daily collected and the presence of oocysts was examined on slides using 0.17% green malachite dye. The total yield reached 1.5x1010 oocysts, with a peak production on the 7th day, confirming the infectious process and the role of calf infection in the potential risk for environmental contamination.
