The antibiotics now used in the treatment of ame--biasis are believed to act primarily on the necessary bacterial associates of the amebae, thereby indirectly affecting the survival of the parasite (1, 2). Recently Hanson and Eble (3) have reported a new antibiotic, fumagillin, which has little antibacterial and anti-fungal activity. Subsequent in vitro experiments and animal studies by McCowen et al.(4) have shown this antibiotic to have marked amebicidal activity. The present note reports our experiences with this antibiotic in adolescent and adult male patients who were hospitalized because of infection with the large race of Endamoeba histolytica. Of 22 patients treated in this series, 12 were asymptomatic, nine had symptoms of mild gastrointestinal irritation, and one had severe amebic dysentery. Fumagillin was administered orally in gelatin capsules to 18 patients for 14 days. Two patients received 5 mg daily; two, 5 mg twice daily; three, 10 mg twice daily; four, 35 mg daily in three divided doses; and seven, 50 mg daily in three divided doses. Four other patients were treated for 7 days. One received the 35-mg dosage, and three received the 50-mg dosage.Laboratory studies on each patient consisted of frequent stool and urine examinations, stool and urine cultures, complete blood counts, blood urea nitrogen determinations, urea clearances, electrocardiography, and a battery of eight liver function tests, including prothrombin concentrations. Thiosulfate clearances were done on four patients, and in one patient the renal vein was catheterized and p-aminohippuric acid and creatinine extractions were performed. Evidence of therapeutic impairment of the hepatic, renal, or cardiovascular systems was not revealed by any of the clinical or laboratory procedures used in this study. Many of the patients had evidence of hepatic and renal involvement caused by schistosomiasis, but in none was the pre-existing disease aggravated. Signs of toxicity were few and of little significance. Two patients receiving 50 mg daily complained of dizziness. In one this subsided while he was still receiving fumagillin, and in the other it subsided the day after the completion of therapy. Four other patients at thisdosage complained of a loss of appetite without nausea or vomiting, but none lost weight during the period of treatment. The disappearance of E. histolytica was prompt in
