Experimental immunization against cutaneous leishmaniasis using Leishmania major subcellular fractions alone or in combination with Phlebotomus duboscqi gut antigens.

Leishmania major-derived flagella and nuclear fractions, and a combination of flagella and sand fly gut antigens were assessed for protection against L. major infection in BALB/c mice. Mice immunized with flagella antigen developed a severe infection while nuclear fraction-immunized animals were partially protected at the onset of infection from week 1 to 4 post challenge. A combination/cock tail of flagella and sand fly gut antigens protected animals at a later stage from week 10 to 14 post-infection. Surviving cocktail-immunized animals did not ulcerate, and parasites did not metastasize to the viscera. These results provide preliminary evidence of the potential of a cock tail antigen derived from Leishmania flagella and sand fly gut in the protection against cutaneous leishmaniasis caused by L. major.
