Abstract
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.
摘要
我们在3个犊牛隐孢子虫病流行的商业化奶牛场，检查了围产期奶牛在产犊后12小时内是否排出微小隐孢子虫卵囊。使用一种每克粪便中能检测到低至1个卵囊的诊断方法，我们在43头奶牛产犊后12小时内采集的86份粪便样本中，未发现微小隐孢子虫卵囊的迹象。
