  • Method for separating fractions of avian eggs exclusively containing IgA and IgM antibodies
    Patent number: 8618268
    Abstract: The present invention provides the method of obtaining IgA and IgM antibodies from chicken egg whites. The method involves separating chicken egg whites into two fractions which contain IgA and IgM antibodies exclusively. This separation method consists of raising the volume of the egg whites using purified water, lowering the pH of said volume, filtering the IgM fraction from said volume, precipitating the IgA fraction from the remaining volume, dialyzing the IgA fraction and drying the IgA and IgM fractions.
    Type: Grant

  • Egg White Antibodies for Prevention and Treatment of Specific Localized Intestinal Infections and Diseases Associated with a Pathogenic Organism or Molecule
    Publication number: 20130011410
    Abstract: The present invention provides the method for prevention and treatment of specific localized intestinal infections and diseases using IgA and IgM antibodies obtained from the eggs of hens which have been hyperimmunized to the same specific infections and diseases. The invention describes the high functionality of IgA and IgM antibodies present in the white of an egg from a hyperimmunized chicken as compared to the IgY from the same egg. The invention also describes the resistance of IgA and IgM to low pH environments such as stomach acids. The invention also describes the inhibition of bacterial growth when bacteria are exposed to IgA antibodies specific to said bacteria together with lysozyme from egg whites.
