  • Publication number: 20060083750
    Abstract: The invention provides a vaccine including an isolated Als protein family member having cell adhesion activity, or an immunogenic fragment thereof, with an adjuvant in a pharmaceutically acceptable medium. The invention also provides a method of treating or preventing disseminated candidiasis. The method includes administering an immunogenic amount of a vaccine an isolated Als protein family member having cell adhesion activity, or an immunogenic fragment thereof, in a pharmaceutically acceptable medium. A method of treating or preventing disseminated candidiasis also is provided that includes administering an effective amount of an isolated Als protein family member having cell adhesion activity, or an functional fragment thereof, to inhibit the binding or invasion of Candida to a host cell or tissue.
