Immune response of BALB/c mice against an experimental vaccine of Alum precipitated autoclaved Leishmania major (Alum-ALM) mixed with BCG or Mycobacterium vaccae.
Immune response in BALB/c mice immunized 3 times with different doses (50 μg or 200 μg of protein) of Alum precipitated autoclaved Leishmania major (Alum-ALM) mixed with either BCG (1x10(7); CFU) or different doses of killed Mycobacterium vaccae (1x10(6), 1x10(7)) was assessed. Mice immunized with low dose of Alum-ALM mixed with either BCG or low M. vaccae showed a significantly higher IFN-gamma production and a lower IL-4 level and a significantly lower parasite burden compared to the control PBS injected group. It seems that immunization with a low dose of Alum-ALM mixed with an adjuvant induces a Th1 type of immune response in susceptible BALB/c mice.
