After suggestive studies in vitro and trials in 49 macaques, 52 episodes of amebic infection in mentally defective children were treated with erythromycin alone, with fumagillin alone, and with these antibiotics in combination. Two recurrences of 17 treated cases were noted after erythromycin therapy, 5 of 21 after the two antibiotics were given concurrently, and 6 of 14 after fumagillin was given alone. The final test regimes followed by the 13 human patients whose infection recurred, provided clearance for all but one of the original group of patients having E. histolytica infection.
