Abstract:
The present disclosure relates to methods and compositions administered to the lymphatic tissue of an animal to prevent or reduce the incidence of disease or disease symptoms caused by one or more disease causing entities. Tonsillar compositions can be administered to the lymphatic tissue in the oral/nasal region of the animal and can include avian antibodies from eggs of hens inoculated with one or more target disease causing entities. Treating the lymphatic tissue in the oral/nasal region with the compositions described herein can reduce or prevent the disease causing entities from adhering to the lymphatic tissue resulting in reduced infection rates. The present disclosure also relates to oral compositions that can be used to reduce or eliminate oral pathogens in animals.
Abstract:
A microbial adherence inhibitor in the form of fowl egg antibodies is disclosed, along with the method of making it and methods of using it. The inhibitor functions by substantially preventing the attachment of adherence of colony-forming immunogens in the respiratory tracts of host animals and humans. The inhibitor is made by inoculating female birds with the immunogen, harvesting the eggs which contain antibodies to the immunogen, and separating the yolk and albumin from the shells of the eggs. The yolk and albumin contents are administered to animals or human by distributing the contents directly or introducing the contents entrained in air. The adherence inhibiting material can be formulated for use in a variety of ways such as an oral spray or a nasal spray. These formulations can be effective to prevent or reduce respiratory illnesses in animals and humans.
Abstract:
Neutralizing antibodies through recombinant protein expression were identified by mining antibody repertoires by high-throughput second generation sequencing. Sequencing across the majority of light and heavy chain variable regions of chicken immunoglobulins was performed at two immunological time points: a non-immune (naive) state and a post-hyperimmunization state. The mRNA was extracted from unsorted and unselected PBMC populations and identification of antigen-specific antibody sequences leveraged the significant disparity of abundance of an individual B cell clone in non-immune and immunized states. Through bioinformatic analysis, candidate amino acid sequences for variable heavy chain and light chains were identified. Recombinant polypeptides with the binding domains having the identified amino acid sequences for variable heavy chain and light chains were expressed and screened using immunoassays to confirm antigen-specificity.
Abstract:
Compositions for reducing the emission of methane by ruminant animals are disclosed. The compositions include avian antibodies against methanogens generally found in the rumen of the animals. Egg contents of eggs from female birds inoculated with immunogenic compositions containing one or more methanogens or antigens derived from methanogens are used. The antibodies in the egg contents may be used directly without further purification, may be partially purified or purified. The compositions may be administered in drinking water or in animal feed. Administering of the anti-methanogenic composition reduces the emission of methane and increases the efficiency of feed conversion.

Abstract:
A method for the production of antibodies or microbial adherents administers is disclosed. The antibodies or microbial adherents inhibitors are administered to a patient suffering from strep throat to substantially prevent the adherents of colony-forming immunogens or haptens in the throat of the patient. Application of the antibodies should decrease the colonization of the oropharynx, and therefore decrease symptoms of the sore inflamed throat and ultimately decrease the need for antibiotics.
