Abstract:
:Mast cell-deficient W/Wv mice and their mast cell-sufficient littermates were given infections of Trichinella spiralis. W/Wv mice were slower than their littermates to expel adult T. spiralis. Repair of the mast cell deficiency of W/Wv mice by bone marrow grafting was accompanied by accelerated expulsion of T. spiralis.
