The authors investigated serological and stool examinations of amebiasis in the Mississippi Psychiatric Hospital in the fall of 1972. A total of 127 confirmed cases of amoebiasis occurred in the hospital during the 20 years from 1953 to 1972, accounting for 2.6% of the total number of deaths. Of the 127 cases, 67 (53%) found Entamoeba histolytica trophozoites on autopsy or biopsy. From 1953 to 1971, patients died of amebiasis each year accounted for 0 to 5.3 ‰ of the number of inpatients, with an average of 1.5 ‰. A total of 351 cases (10%) of the sera were randomly selected to be positive for the indirect hemagglutination assay (IHA) of Entamoeba histolytica
