Isospora belli and Cryptosporidium sp. from a patient not suspected of having acquired immunodeficiency syndrome

Abstract Several protozoa including Cryptosporidium sp. and Isosporabelli were found in a stool specimen from a patient not suspected of having Acquired Immunodeficiency Syndrome (AIDS). As a result of the parasitologic findings, serologic tests were ordered that verified the diagnosis of AIDS. All stool specimens are routinely tested for presence of acid fast organisms with a modified acid fast technique.
