Abstract: The invention relates to novet Borrelia, and OspA antigens derived therefrom. These antigens show little homology with known OspA's and are therefore useful as vaccine and diagnostic reagents. Multicomponent vaccines based on OspA's from different Borrelia groups are also disclosed.

Abstract: A method of cultivating bacteria having genes in plasmids which code for surface or membrane bound antigens or other proteins and which are expressed in a temperature regulated manner for the production of desired bacterial products, is disclosed. The bacteria are first cultivated in a culture medium to an inoculum under such temperature conditions that the bacteria retain their plasmids and no expression occurs, e.g. 20.degree. C., and then in a culture medium under such temperature conditions that expression occurs and before the bacteria lose their plasmids they are harvested, and the desired product is isolated.

Abstract: The invention provides ribA polypeptides and polynucleotides encoding ribA polypeptides and methods for producing such polypeptides by recombinant techniques. Also provided are methods for utilizing ribA polypeptides to screen for antibacterial compounds.

Abstract: A novel hybrid protein is provided which comprises a portion of the CS protein of P. falciparum and the surface antigen of Hepatitis B virus. The use of this protein for vaccination purposes is disclosed.

Abstract: A method of reversing or preventing immunosuppression or antigenic interference associated with combination vaccines in mammals, is disclosed. Cytokines, or cytokine inducer, are administered in conjunction with the combination vaccine. The cytokine or cytokine inducer can be administered concurrently with or subsequently to the vaccine, and can be recombinantly produced or isolated from cell culture.

Abstract: Described is a vaccine against Actinobacillus pleuropneumoniae (APP) comprising genetically defined biochemically attenuated mutant of APP that requires riboflavin and is attenuated in vivo.

Abstract: The present invention encompasses methods for reducing or inhibiting growth factor in cancer cells and tissues. More particularly immunogenic growth factor-containing compositions are administered to a human or animal with a cancer or tumor. The immunogenic compositions elicit the production of antibodies specific for growth factor which reduce the level of circulating growth factor, thus reducing or eliminating the proliferation of cancer. The present invention encompasses growth factor-containing liposomes and vesicles having portions of growth factor externally presented on their surfaces. The present invention also includes antibodies specific for growth factor. Thus, according to the present invention, growth factor levels are reduced either by active immunization of an individual using immunogenic growth factor-containing compositions or by passive immunization via administering to the individual an antibody or a group of antibodies specific for growth factor.

Abstract: Immunological adjuvant containing GMDP (N-acetyl-glucos-aminyl-N-acetylmuramyl-L-alanyl-D-isoglutamine) and a colloidal, ultrafiltrable solution of solid, biodegradable lipids suitable as an additive in veterinary and human vaccines.

Abstract: Methods are disclosed for administering Peptide YY (PYY) receptor agonists to birds in ovo to promote altricial development of the intestinal tract of neonatal birds. Enhanced altricial development of the small intestine in hatchling birds results in an increased absorption of nutrients from the small intestine without a concomitant increase in energy expenditure, thereby resulting in an improved efficiency of nutrient utilization, enhanced rate of post-hatch growth, and reduced post-hatch mortality rate in PYY-treated birds.

Abstract: The present invention relates to contraceptive vaccines based on cloned zona pellucida genes and the strategy of alloimmunization with zona pellucida polypeptides. In particular, the present invention relates to a contraceptive vaccine for use in a mammalian female comprising a polypeptide which displays at least one epitope for binding of an antibody that inhibits fertilization of an oocyte by a sperm. This epitope is from a zona pellucida procein of the species in which the said vaccine is used. This invention relates, more particularly, to such vaccines wherein the zona pellucida protein is either the ZP3 or the ZP2 or the ZP1 protein or the mouse or homologues of these proteins in some other mammalian species. Further, this invention comprehends vaccines comprising a synthetic peptide that displays an epitope for such an antibody that inhibits fertilization. In addition, this invention relates to cloned DNA segments variously encoding the mouse ZP3 or ZP2 proteins or the human ZP3 or ZP2 protein.

Abstract: Diphtheria toxin polypeptides comprising a mutant R binding domain exhibit reduced target cell binding and may be used as vaccines to immunize a mammal against infection by Corynebacterium diphtheria.

Abstract: A consensus poptide of 36 amino acids has been designed which acts as an immunogen raising antibodies against the proteins of all members of the E. coli family CS4-CFA/1. While the N-terminus of members of this family of organisms shows a high degree of identity, the remainder of the sequence of the proteins shows much less homology across the strains. The region of the protein represented in the subunit encompasses known linear B- and T-cell epitopes of CFA/I. The consensus peptide has a high level of homology to strains bearing six different colonization factors.

Abstract: Compounds and methods are provided for diagnosing Leishmania infection. Disclosed compounds include polypeptides that contain at least an epitope of the Leishmania chagasi acidic ribosomal antigen LcP0, or a variant thereof. Such compounds are useful in a variety of immunoassays for detecting Leishmania infection and for identifying individuals with asymptomatic infections that are likely to progress to acute visceral leishmaniasis. The polypeptide compounds are further useful in vaccines and pharmaceutical compositions for preventing leishmaniasis.

Abstract: 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.

Abstract: The present invention relates to a live attenuated strain of the bacterium Streptococcus equi, a pathogen causing strangles in horses. The invention also relates to a vaccine against strangles, methods for the preparation of such a vaccine and to the use of the strain for the preparation of such a vaccine.

Abstract: The invention provides novel uses of EGF and vaccine compositions comprising EGF. In particular, autologous EGF, or a fragment or a derivative thereof, is used as an active immunization against the proliferation of EGF-dependent tumors, or other EGF-dependent diseases. Autologous EGF is preferably coupled to a carrier protein, such as tetanus toxoid or Cholera toxin B chain. The vaccine compositions according to the invention will usually comprise an adjuvant such as aluminum hydroxide.
