Full text not available from this repository. (Request a copy)Alveolar echinococcosis (AE), caused by the larval stage (metacestode) of the tapeworm Echinococcus multilocularis, exhibits very similar disease characteristics in humans and rodents. Recently, it has been shown that an over-expression of the parasite 14-3-3 protein could be associated to the proliferative growth of the E. multilocularis metacestode. We now demonstrate the expression of this protein at the E. multilocularis oncospheral stage as well. A recombinant E. multilocularis 14-3-3 protein (E14t) was used to vaccinate mice against either primary or secondary experimental E. multilocularis infection in BALB/c mice. Conversely to non-vaccinated but control infected mice, which developed a very weak anti-E14t response during infection, the response elicited in the E14t-vaccinated and subsequently infected animals exhibited a strong reactivity against the parasite 14-3-3 protein. Major differences became apparent between secondarily and primarily infected animals: whereas no protection against secondary infection was achieved by vaccination, vaccinated animals were protected by 97% against challenge primary infection with 2000 E. multilocularis eggs. Consequently, the parasite 14-3-3 molecule appears crucially involved in the early stage of the host-parasite interplay and exhibits potential to be used as target molecule for the development of protective tools against AE.
