This study was performed to investigate experimental transmission of Cryptosporidium parvum in a calf. A 25-day-old Korean native calf was inoculated per os with 1 x 10(6) C. parvum oocysts isolated from a Korean mouse. The calf commenced oocyst discharge in feces on post-inoculation day 4, and continued until the day 11. The number of discharged oocysts peaked (4.9 x 10(5)) on post-inoculation day 6. However, the calf did not show signs of diarrhea. The present results indicate that C. parvum is cross-transmissible between the calf and the mouse.
本研究旨在调查微小隐孢子虫在犊牛中的实验性传播情况。一头25日龄的韩国本地犊牛经口接种了从一只韩国小鼠分离出的1×10⁶个微小隐孢子虫卵囊。犊牛在接种后第4天开始在粪便中排出卵囊，并持续到第11天。排出的卵囊数量在接种后第6天达到峰值（4.9×10⁵）。然而，犊牛未表现出腹泻症状。目前的结果表明，微小隐孢子虫可在犊牛和小鼠之间交叉传播。
