Leishmania braziliensis promastigotes

In this section NR membranes with colloidal incorporation of gold nanoparticles are used, synthesized by an in situ method (NR/Au) at different reduction times, in order to evaluate the physiological behaviour of Leishmania braziliensis promastigotes cultured in axenic medium, in a colony of 7 weeks old, evaluating the increase in kinetics in relation to the permanence time of the membranes in the culture medium as a function of reduction time and temperature of preparations of NR membranes. 

A series of monomeric and dimeric naphthoquinones with potential for treatment of Leishmania infections were identified in vitro using a direct cytotoxicity assay against extracellular promastigotes of Leishmania spp. [196,197]. Lapachol was evaluated in vitro against intracellular amastigotes of Leishmania braziliensis and then tested in an animal model (hamster) to try to reproduce the leishmanicidal activity. In vitro lapachol exhibited an... 

Population growth kinetics of promastigotes of Leishmania braziliensis (LB) exposed to samples of vulcanized NR and NR/NZF nanocomposites with different concentrations of nanoparticles. 

Much of our investigation has been done using the promastigote form of three species of leishmania donovani, L. braziliensis,...
