title: Responses of Leishmania (Viannia) braziliensis cutaneous infection to N-methylglucamine antimoniate in the rhesus monkey (Macaca mulatta) model.
abstract: The antileishmanial efficacy of the reference drug N-methylglucamine antimoniate (Glucantime) was evaluated in groups of rhesus monkeys with acute and chronic Leishmania (Viannia) braziliensis cutaneous infection. The therapeutic responses in experimental animals to either a low dose (5 mg/kg body wt/day for 28 days) or a routine dose (20 mg/kg/day for 28 days) of pentavalent antimony were similar to those reported in the human disease. Primates were cured of their lesions after treatment, but with cryptic parasitism and/or relapse. The rhesus model of L. (V.) braziliensis cutaneous leishmaniasis therefore provides an additional resource for preclinical trials with newer drugs.
