Abstract

Approximately 30% of foxes given two doses of an inactivated rabies antigen delivered directly into the intestinal tract developed an immune response as measured by rabies serum neutralizing antibodies. Seven of ten previously immunized foxes showed an anamnestic response following a booster dose of inactivated rabies antigen delivered to the intestinal lumen. Stomach and particularly intestinal contents were destructive to rabies antigen and virus. This effect could be partially neutralized in vitro by the addition of Questran and soybean trypsin inhibitor. Small enteric coated tablets fed to foxes in a hamburger bolus remained in the stomach for up to 13 hours and therefore would provide a poor vehicle for the delivery of antigen to the intestinal tract.
