Abstract
Relapse of chronicT. brucei infections was completely prevented by treating with either diminazene aceturate (Berenil) at 40 mg/kg or suramin (Germanin) at 20mg/kg followed by four doses of the 2-substituted 5-nitroimidazole (Fexinidazole)(Hoe 239). None of these drugs administered singly elicited 100% permanent cures although a high percentage of the mice were cured with four doses of Fexinidazole at 250 mg/kg. A single dose of 20 mg/kg suramin followed by four daily doses of 30 mg/kg Fexinidazole will effectively eliminate all the trypanosomes from the brains of chronically infected mice.
