The present invention provides ungulate animals, tissue and organs as well as cells and cell lines derived from such animals, tissue and organs, which lack expression of functional endogenous immunoglobulin loci. The present invention also provides ungulate animals, tissue and organs as well as cells and cell lines derived from such animals, tissue and organs, which express xenogenous, such as human, immunoglobulin loci. The present invention further provides ungulate, such as porcine genomic DNA sequence of porcine heavy and light chain immunogobulins. Such animals, tissues, organs and cells can be used in research and medical therapy. In addition, methods are provided to prepare such animals, organs, tissues, and cells.

Porcine animals, tissue and organs as well as cells and cell lines derived from such animals are provided that lack functional endogenous immunoglobulin loci and are deficient in immunoglobulin expression and B-cells. These animals are useful as model systems for research and for development of new pharmaceutical and biological agents. In addition, methods are provided to prepare such animals.

The present invention is generally directed to compositions and methods for the treatment of an infectious disease of the foot of an animal. One aspect of the invention is directed to a method for preventing and / or treating one or more infectious diseases of the hoof in animals, comprising: preparing a copper-free and zinc-free composition comprising at least one cross-linking agent, wherein the cross-linking agent is not formaldehyde; and administering the composition to a lower leg and hoof area of said animal to prevent and / or treat said one or more infectious diseases. Another aspect of the invention is directed to a copper-free and zinc-free composition for the treatment and / or prevention of one or more infectious diseases of the hoof in animals, comprising at least one cross-linking agent, wherein said cross-linking agent is not formaldehyde. The present invention is also directed to a method for treating and / or preventing papillomatous digital dermatitis in an ungulate, comprising: preparing a copper-free and zinc-free composition comprising at least one cross-linking agent and at least one quaternary ammonium compound; and spraying or applying in a foam a therapeutically effective amount of said composition to a lower leg and hoof area of said ungulate in order to treat and / or prevent said papillomatous digitial dermatitis.

The present invention relates to a method of producing an ungulate having both copies of the IgM heavy chain (mu) rag-1 and / or rag-2 gene eliminated from its genome. Animals which have IgM, rag-1 and / or rag-2 eliminated from their genome are unable to conduct the gene rearrangements that are necessary to generate the antigen receptors of B- or T-lymphocytes, and therefore will not develop native B- or T-cells. Because they are unable to produce B- and T-lymphocytes, these IgM, rag-1, or rag-2 ungulates cannot reject human hematopoietic stem cell preparations, and B- and T-lymphocytes which develop therefrom. Therefore, the present invention also involves injecting into IgM, rag-1, and / or rag-2 deficient ungulates, in utero or shortly after birth, human B- and T-lymphocytes whose immune systems produce human immunoglobulin that can be processed for therapeutic uses in humans.

The present invention is directed to immunodynamic complexes that, in embodiments of the invention, are surprisingly antimicrobial and immunoactive. By “immunoactive,” it is meant that such compositions are capable of modulating, stimulating and repairing the immune system. Moreover, in embodiments of the invention, an immunodynamic complex is capable of supporting, maintaining and / or enhancing the structure and function of the immune system. In addition, this invention is directed to a method for preparing and using such compositions. Embodiments of the immunodynamic complexes of this invention are prepared from lacteal secretions derived from ungulates, such as cows.
