Human cryptosporidiosis in the acquired immune deficiency syndrome

Abstract

We studied two cases of cryptosporidiosis in patients with acquired immune deficiency syndrome. In one patient, the gallbladder was affected in addition to gastric and intestinal involvements. This is the first human case in which Cryptosporidium has been found in the biliary tract. It is important that pathologists become aware of this protozoan infection since the number of patients with it is likely to increase in the near future.
