Method and use of compositions comprising lignosulfonate and substantially free of elemental sulphur for pathogenic attenuation

The use of a composition which comprises lignosulfonate and is substantially free of elemental sulphur for the prevention and treatment of pathogenic and medical disorders in humans and animals. In some embodiments the lignosulfonate is radically polymerized. In some embodiments the composition is formulated as an animal feed additive or supplement. The disclosure also encompasses a method of preventing or treating a pathogenic or medical disorder in a human or animal subject by administering the composition to the subject in an effective dose to attenuate the pathogenic effect of a pathogen or other biological agent, thereby enabling the subject to mount an effective immune response to the pathogen or other biological agent. The composition can be used in the prevention or treatment of a wide range of pathogenic or medical disorders including disorders caused by microbial pathogens; disorders caused by viral pathogens; disorders caused by prions; disorders caused by protists; disorders caused by fungi; disorders caused by parasites; lung and airway disorders; bone, joint and muscle disorders; digestive disorders; hormonal disorders; cancer; auto immune disorders; neurodegenerative disorders; skin disorders; and sexual and reproductive disorders. In one particular embodiment the composition is formulated for treatment of Type I diabetes.
