%X Trypanosomes from animals are potential pathogens for humans. Several human cases infected by Try-panosoma lewisi, a parasite of rats, have been reported. The number of these infections is possibly underestimated. Some infections were self-cured, others required treatment with drugs used in human African trypanosomosis. An in vitro evaluation of these drugs and fexinidazole, a new oral drug candidate, has been performed against T. lewisi in comparison with T. brucei gambiense. All have comparable activities against the two parasites. Suramin was not effective. In vivo, drugs were tested in rats immunosuppressed by cyclophosphamide. The best efficacy was obtained for fexinidazole, and pentamidine (15 mg/kg): rats were cured in 7 and 10 days respectively. Rats receiving nifurtimoxeflornithine combination therapy (NECT) or pentamidine (4 mg/kg) were cured after 28 days, while melarsoprol was weakly active. The identification of efficient drugs with reduced toxicity will help in the management of new cases of atypical trypanosomosis.
