The anti-Candida vaccine based on the recombinant N-terminal domain of Als1p is broadly active against disseminated candidiasis.

We have previously shown that vaccination with a vaccine based on the recombinant N-terminal domain of Als1p (rAls1p-N) protected BALB/c mice against disseminated infection caused by a single strain of Candida albicans (A. S. Ibrahim, B. J. Spellberg, V. Avenissian, Y. Fu, S. G. Filler, and J. E. Edwards, Jr., Infect. Immun. 73:999-1005, 2005, and B. J. Spellberg, A. S. Ibrahim, V. Avenissian, S. G. Filler, C. Myers, Y. Fu, and J. E. Edwards, Jr., Infect. Immun. 73:6191-6193, 2005). Here we show that the rAls1p-N vaccine also improves survival of outbred mice from disseminated candidiasis and that it is active against multiple virulent strains of C. albicans and non-C. albicans spp.
