In vitro study of the efficacy of Solanum nigrum against Leishmania major (original) (raw)
Leishmania parasites (Kinetoplastida: Trypanosomatidae) are obligate intracellular parasites of macrophages that causes visceral and cutaneous leishmaniases. Currently, there is inadequate therapeutic interventions to manage this endemic tropical disease, transmitted mainly by phlebotomine sandflies hence there is need to develop affordable and effective therapeutic measures. This study determined the in vitro efficacy of Solanum nigrum methanolic and aqueous plant extracts on Leishmania major parasites. Cytotoxic effects of the extracts were determined using vero cells and reported as percentage viability of the cells. The promastigote parasites of Leishmania major were cultured and grown for 3 days in different concentrations of extracts to determine the MIC and IC50 values. The in vitro antileishmanial efficacy was done on macrophages infected with L. major amastigote parasites and then treated with extracts in varying concentrations. The study revealed that all the test extract...
