Note: Be sure to specify how you want the oocysts processed. We have found that ether treatments to remove fecal lipid will wreck havoc with most antibody detection procedures. Potassium dichromate treatments also affect antibody binding significantly in some assays. Moore et al., 1998, Int. J. Parasitol. 28: 1205-1212 has demonstrated some of this.
