Investigation of cryptosporidial infection in calves in San Bernardino County, California.
Cryptosporidium is a protozoan parasite that inhabits the intestinal epithelium of calves, lambs, foals, pigs, and poultry. Of the 500 calves studied, 95 calves had diarrhea and 20 (21.05%) of those were infected with Cryptosporidium; only 8 (1.9%) of the remaining 405 nondiarrheic calves had Cryptosporidium oocysts in their feces.
