Use of polyclonal antibodies against clostridium difficile for treatment of inflammatory bowel disease

摘要

The present invention provides a polyclonal antibody composition prepared from eggs of hens immunized with virulent antigens of Clostridium difficile for use in the treatment and prevention of C. difficile infections in subjects with Inflammatory Bowel Disease including Ulcerative colitis and Crohn's disease. Respective groups of hens are immunized with Toxin A or Toxin B of Clostridium difficile or a Clostridium difficile spore preparation. The polyclonal antibodies are recovered from eggs pooled from the immunized hens and the resulting antibody-egg powder is administered orally in a therapeutically effective amount to individuals infected with or suspected of being infected with C. difficile.
