Abstract: The present invention relates to Lawsonia intracellularis vaccines and methods for protecting against and diagnosing L. intracellularis infection. The products and processes of the invention are attainable, in part, as the result of an improved method for cultivating large scale supplies of L. intracellularis, including both a novel isolate of L. intracellularis of European origin and a method of preparing a lyophilized product containing the attenuated European isolate as vaccine product.

Abstract: The invention includes kits for producing and using immunogenic compositions that include swine infertility and respiratory virus. The invention also includes vaccines and sera for treatment of Mystery Swine Disease (MSD), a method for producing the vaccine, methods for diagnosis of MSD, a viral agent that will mimic “mystery swine disease” and antibodies to the viral agent useful in diagnosis and treatment of MSD. The serum contains mammalian antibodies which are effective in treating MSD.

Abstract: A vaccine for protecting a horse against diseases associated with EHV-1 and/or EHV-4 is provided. The vaccine commonly includes inactivated EHV-1 (e.g., chemically inactivated EHV-1 KyA virus) and an adjuvant. The adjuvant can include a cross-linked olefinically unsaturated carboxylic acid polymer which may have bioadhesive properties. The vaccine may also include antigens against other equine pathogens such as inactivated EHV-4 and inactivated A1 and/or A2 strains of equine influenza virus. Methods for protecting horses against diseases associated with EHV-1 and/or EHV-4 and methods of producing the equine herpesvirus vaccine are also provided.
