 Diarrhea in Neonatal Ruminants - The Merck Veterinary Manual
Diarrhea in calves and lambs also has been associated with enteropathogenic E coli that adhere to the intestine to produce an attaching and effacing lesion, with dissolution of the brush border and loss of microvillous structure at the site of attachment, a decrease in enzyme activity, and changes in ion transport in the intestine.
This is usually the result of villous atrophy, in which the loss of mature enterocytes at the tips of the villi results both in a decrease in villous height (with a consequent decrease in the surface area for absorption) and in loss of the brush border digestive enzymes.
Diarrhea due solely to Cryptosporidium spp is often mild and self-limiting, although the severity may be related to the general strength of the calf and to the intensity of challenge with the organism.

When this immunologic reaction damages the finger-like surface projections, the villi, in the small intestine (a process called villous atrophy), it is called celiac disease (or sometimes celiac sprue or gluten-sensitive enteropathy).
However, several studies have now revealed that it is only those with significant villous atrophy of the small intestine who regularly show a positive antiendomysial or antitissue transglutaminase antibody, the specific tests relied upon most heavily for diagnosis of gluten-induced disease.
