摘要:
An improved vaccine against infectious bovine keratoconjunctivitis is provided which is derived from an appropriate Moraxella bovis strain cultured in a relatively low available iron medium which induces the expression of significant quantities of approximately 78 kDa and 104 kDa outer membrane proteins. The vaccine may be prepared using the entire cell culture or fractions thereof.
摘要:
Improved, low cost vaccines for administration to living subjects such as mammals and birds are provided, which include killed recombinantly modified microorganisms (whole cell recombinant bacterin vaccine), the latter including recombinant DNA encoding at least one protective protein (e.g., an antigenic protein) which has been expressed by the microorganisms prior to killing thereof. The protective protein(s) are operable to prevent or reduce the severity of a disease of the subject. The vaccine preparations of the invention do not require separation of the protective protein(s) from the host recombinant microorganism(s), thereby materially decreasing the complexity and cost of the vaccine formulations. A preferred vaccine against kennel cough includes recombinantly modified microorganisms which express protective antigens containing pertactin and filamentous hemagglutinin protein products.
摘要:
An improved method and vaccine is provided for the immunization of swine against infectious diseases caused by RTX toxin-secreting bacteria (e.g., porcine pleuropneumonia) which comprises administering to swine an effective amount of a live, immunizing, RTX toxin-secreting organism which induces in the swine a sufficiently high RTX toxin-neutralizing antibody titer to at least prevent clinical symptoms of the disease in the swine. For example, an intranasally administered, live, low virulence strain of A. suis (EM1) confers immunity upon swine against challenge with a virulent, disease-causing strain of A. pleuropneunmoniae.

摘要:
Water-soluble, cell permeable aldose reductase inhibitors are presented. These compounds prevent the effects of galactosemia in patients. The compounds prevent both the accumulation of polyols and the change in levels of protein kinase C gamma observed during diabetes and galactosemia.
