我们检查了 3 个患有犊牛隐孢子虫病的商业奶牛场，围产期奶牛是否在产犊后 12 小时内排出小隐孢子虫卵囊。使用每克粪便可检测到 1 个卵囊的诊断方法，我们在 43 头奶牛产犊后 12 小时内收集的 86 个粪便样本中没有发现微小隐球菌卵囊的证据。
We examined whether periparturient dairy cattle shed Cryptosporidium parvum oocysts within 12 hr of calving on 3 commercial dairy farms endemic for calfhood cryptosporidiosis. Using a diagnostic method that can detect as few as 1 oocyst per gram of feces, we found no evidence of C. parvum oocysts in 86 fecal samples collected within 12 hr of calving from 43 dairy cows.
