Abstract: The present invention provides probiotic compositions and methods for improving animal health, particularly improving and enhancing vaccine response. The probiotic compositions include one or more isolated strains of Lactobacillus species bacteria which colonizes the gastrointestinal tract to increase the health and enhance the immune system and immune response of an animal.

Abstract: The present invention relates to probiotic compositions and methods for improving animal health and animal production. The probiotic compositions include one, two, three, or more isolated strains of novel Bacillus strains which are capable of colonizing the gastrointestinal tract to improve the health of an animal. The probiotic compositions include a combination of at least one Bacillus amyloliquefaciens strain and a Bacillus subtilis strain.

Abstract: Compositions and methods for controlling undesirable microbes, such as pathogenic bacteria, are provided. Such compositions and methods comprise a bacterial strain that can be used as a probiotic for animals. Therefore, methods for controlling undesirable microbes, such as pathogenic bacteria, in the gastrointestinal tract, for example, of an animal and methods for improving animal health are also provided.

Abstract: The present invention relates to media formulations free of swine serum and animal (primarily bovine brain and spinal cord) origin ingredients for Mycoplasma growth. Media formulations are rationally designed to preserve Mycoplasma antigenicity. Mycoplasma grown in these media formulations are useful in vaccines, particularly multivalent swine vaccines.

Abstract: The present invention relates to probiotic compositions and methods for increasing animal health. The probiotic compositions include one or more isolated strains of novel Lactobacillus reuteri strains which colonizes the gastrointestinal tract to increase the health of an animal.

Abstract: The present invention relates to efficient delivery of anti-infective activity, immunomodulatory factors, or growth-promoting biomolecules directly to the digestive tract of an animal via a live delivery platform. The live delivery platform can be a genetically modified microorganism. Delivery can be accomplished with a Lactobacillus sp which colonizes the gastrointestinal tract. The anti-infective activity can be a bacteriocidal or bacteriostatic peptide, an antibody or fragment thereof which specifically recognizes a pathogen, or a phage, or a lytic peptide from a phage which specifically targets a certain pathogen.
