Molecular cloning of components of protective antigenic
preparations have suggested that related parasite fatty acid binding
proteins could form the basis of the well documented protective,
immune cross reactivity between the parasitic trematode worms Fasciola
hepatica and Schistosoma mansoni
. We have now confirmed the cross
protective potential of parasite fatty acid binding proteins and
suggest that it may be possible to produce a single vaccine
that would be effective against at least two parasites, F. hepatica
and S. mansoni of veterinary and human importance respectively.
