Abstract
It has been found that hosts which are susceptible to nematode parasite infections can readily be protected from such infections when the parasites are not adapted for a parasite/host relationship to this host. In particular, feline hosts were immunized against heartworm using a variety of antigens derived from Dirofilaria immitis and related nematodes. Because cats are hosts susceptible to this nonadapted parasite, such antigens are successfully protective.
