Testing of Experimental Compounds against American Mucocutaneous and Cutaneous Leishmaniasis.
Abstract
Leishmania m. mexicana and L. b. panamensis served as standard subspecies for drug screening. Both amastigotes and promastigotes yielded suitable lesions for drug screening, and promastigotes grown in insect media were as infective as amastigotes. In Schneider's drosophila medium, subcultured promastigotes remained infective. Stationary phase cells were more infective in all media tested. Time to lesion development was staged and dose dependent. Using Pentostam and Glucantime to treat developed lesions of L. m. mexicana and L. b. panamensis, we showed that neither drug can cure these infections, leishmania b. panemensis was more sensitive to Glucantine, the SD50 and 90 for these subspecies was greater than that for visceral L. donovani infections. Using L. donovani in BALB/c mice, we showed that: fourteen day assays are highly reliable whether mice are inoculated IC or IV with 10 million splenic amastigotes or promastigotes.
