The prevalence of Cryptosporidium species in 1-2-year-old heifers was determined for 571 animals on 14 dairy farms in seven states on the East Coast of the United States. A fecal specimen collected directly from each heifer was processed to concentrate oocysts that were then examined by polymerase...

Cryptosporidium parvum DNA from 175 neonatal calves on 16 farms in eight eastern states in the United States was subtyped by sequence analysis of the 60-kDa glycoprotein gene to determinate the parasite genetic diversity. Six subtypes of the IIa subtype family were found. Subtype IIaA15G2R1, which...
