Abstract

We report what is, to our knowledge, the first study in which microsporidial infection was detected in elderly human immunodeficiency virus (HIV)--negative patients. Of the 60 elderly patients studied, 47 had diarrhea. Intestinal microsporidiosis due to Enterocytozoon bieneusi was diagnosed in 8 patients (17.02%) by use of Weber's chromotrope-based stain and polymerase chain reaction with species-specific primers. The mean age of these 8 patients was 75 years; 7 had chronic diarrhea and 1 had nonchronic diarrhea. Six of the patients with chronic diarrhea had no other pathogens isolated. In our opinion, elderly patients, because of their special immunological characteristics, should be considered a group at risk for the acquisition of intestinal microsporidiosis.
