Abstract

Jirds were vaccinated by three to five subcutaneous (SC) injections of infective larvae of Brugia pahangi which had been irradiated at 25, 45 or 90 krads from a 60Co source. They were challenged either SC or intraperitoneally. Vaccination with four doses of 50 larvae irradiated with 25 krads produced 49·3% resistance to IP challenge worms and 39·8% against SC challenge worms. Five doses of larvae irradiated with 45 krads produced 62% resistance to SC challenge. Three doses of larvae irradiated with 90 krads produced 74·9% resistance to SC challenge and five doses produced 76·2% resistance. The reasons why irradiated larvae produce resistance whereas normal larvae do not are discussed.
