摘要:
Egg yolks and egg yolk fractions containing effective therapeutic concentrations of avian antibodies against parasitic antigen, and a method of providing passive immunization for the prevention or treatment of intestinal parasitosis by enteral administration of egg yolk antibodies harvested from hyperimmunized avian hens. Also provided are pharmaceutical formulations comprising the egg yolk antibodies.
摘要:
The present invention includes methods and compositions for treating humans and other animals intoxicated with at least one Clostridial toxin by administration of antitoxin. In particular, the antitoxin directed against these toxins is produced in avian species. This avian antitoxin is designed so as to be orally administerable in therapeutic amounts and may be in any form (i.e., as a solid or in aqueous solution).
摘要:
The present invention provides a method for purifying high yields of IgG immunoglobulins from an egg yolk by a single phase separation step using a nonionic detergent.
摘要:
A method of passively immunizing a mammal against a condition caused by an antigen comprising: administering to the mammal immunizing amounts of an antibody obtained from a domesticated fowl which has been immunized against the antigen; the mammal being tolerant to the antibody by virtue of having a history of consumption of antibody containing material derived from the egg of a fowl.
摘要:
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.
摘要:
A modified antibody that binds specifically to folate receptor alpha (FOLR1) and blocks the activity of FOLR1 with an increased binding affinity, an antigen-binding fragment thereof, a composition containing the antibody or fragment, and their uses are disclosed. The modified antibody or antigen-binding fragment thereof may be used for the prevention or treatment of cancer proliferative disorder associated with an increased FOR1 expression, and may also be used for diagnosis of the disease. The proliferative disorder may be cancer.
摘要:
The present invention relates to a stationary phase for the purification of polyclonal anti-Giardia IgG and IgY antibodies, as well as a method for purifying polyclonal anti-Giardia IgG and IgY antibodies by affinity chromatography. The invention also relates to the polyclonal anti-Giardia IgG and IgY antibodies purified by affinity chromatography, which specifically bind to the antigenic proteins CWP1, alpha-giardin 7.3 and kinesin 3. In an additional aspect, the invention relates to a method for diagnosing giardiasis by detection of Giardia in a specific sample, and a kit for diagnosing giardiasis in biological and environmental samples.
摘要:
The present disclosure is directed to interleukin-10 (IL-10) peptides and isolated antibodies that specifically bind to the IL-10 peptides. The IL-10 peptides and the isolated antibodies may be administered alone or as an animal feed additive to treat gastrointestinal protozoan infection in animals.
摘要:
A method and composition for treating enteric pathogen infections in animals suffering from such infections or displaying diseases or conditions consistent with such infections or for preventing or reducing the likelihood of enteric pathogen infections in animals at risk for developing such infections.
