  • Lipoglycan compositions and methods of treating parasitic infections
    Patent number: 7204983
    Abstract: A composition for and a method of eliciting in a vertebrate a protective immune response against an eukaryotic parasite are disclosed. The method includes administering to the vertebrate a composition having a carrier group coupled to an oligosaccharide obtained from a lipoglycan found on the surface of an eukaryote. The composition is administered in an amount sufficient to elicit a protective immune response against the parasite.
