Cryptosporidiosis of the stomach and small intestine in patients with AIDS.

Cryptosporidiosis is a parasitic disease of the gastrointestinal tract that causes a choleralike diarrhea in patients with the acquired immunodeficiency syndrome (AIDS). Review of barium studies of the stomach and small intestine in 16 AIDS patients with cryptosporidiosis showed that the studies were abnormal in 13. Of these, five had moderate or marked prominence of the mucosal folds, and eight had slight prominence.
