A high-throughput drug screen for Entamoeba histolytica identifies a new lead and target.

ABSTRACT: Entamoeba histolytica, a protozoan intestinal parasite, is the causative agent of human amebiasis. Amebiasis is the fourth leading cause of death and the third leading cause of morbidity due to protozoan infections worldwide(1), resulting in ~70,000 deaths annually. E. histolytica has been listed by the National Institutes of Health as a category B priority biodefense pathogen in the United States. Treatment relies on metronidazole(2), which has adverse effects(3), and potential resistance of E. histolytica to the drug is an increasing concern(4,5). To facilitate drug screening for this anaerobic protozoan, we developed and validated an automated, high-throughput screen (HTS). This screen identified auranofin, a US Food and Drug Administration (FDA)-approved drug used therapeutically for r
