Study demonstrated for the first time that a recombinant stage-specific hydrophilic surface protein of Leishmania donovani, recombinant hydrophilic acylated surface protein B1 (HASPB1), is able to confer protection against experimental challenge with L. donovani in BALB/c mice (Stäger et al., 2000).
