Abstract: The present invention provides compositions and methods for making and using antibodies. A pharmaceutical composition of the invention comprises a selected antigen and a Candida spp. antigen. Selected antigens include, for example, antigens derived from bacteria, yeasts, rickettsias, protozoas, viruses, parasites, and components or fragments thereof. Preferred compositions disclosed include antigens selected from Cryptosporidium spp. and Clostridium spp. The invention further provides for immunizing an animal with a composition of the invention to prepare a composition of immunoglobulins reactive with the selected antigen. The composition of immunoglobulins can be included in nutraceuticals that are ingested or administered enterally.

Abstract: A liquid enteral tube feeding composition contains free amino acids and glutamine in a dipeptide form and prevents creaming out of fat from the composition.

Abstract: The present invention provides a vaccine composition for enhancing the immune response of a mammal against a selected antigen. The vaccine composition of the invention comprises a combination of the selected antigen and a Candida spp. antigen. Selected antigens include, for example, a bacteria, yeast, rickettsia, protozoa, virus, parasite or components thereof. The composition may also contain adjuvants known in the art. A preferred vaccine composition for immunization against the selected antigen Cryptosporidium parvum is disclosed. The invention also provides a method for enhancing the immune response of a mammal against a selected antigen utilizing the vaccine compositions of the invention.

Abstract: The effective treatment of Clostridium difficile associated diseases, such as Clostridium difficile colitis, pseudomembranous colitis and antibiotic associated diarrhea, by administering an antibody having specific activity against Clostridium difficile colitis and toxins thereof alone or in combination with vancomycin, bacitracin or metronidazole is herein described as well as pharmaceutical compositions therefor.

Abstract: Ultrafiltration of whey containing products at an acid pH reduces calcium levels in the concentrate and provides a concentrate that can be consistently microfiltered. The concentrate can be used, for example, in a method of microfiltering milk, milk serum, colostrum, or colostral serum which provides effective bioburden reduction without substantial loss of immunoglobulins.
