Abstract:
A pharmaceutical formulation for parenteral or mucosal administration of antigens and/or vaccines to humans and animals, comprising monoglyceride preparations having at least 80% monoglyceride content and where the acyl group contains from 6 to 24 carbon atoms, together with fatty acids where the number of carbon atoms may be varied between 4 and 22.
Abstract:
Inactivated scours vaccines for immunization and protection of bovine animals from disease caused by infection with bovine rotavirus and bovine coronavirus, which comprise and effective amount of at least one inactivated viral strain are described. Polyvalent inactivated vaccines further comprising an effective amount of an antigenic component which is protective against one or more additional pathogenic organisms or viruses are also disclosed. Said vaccines are prepared from one or more strains of rota- and coronavirus, C. perfringens Type C bacteria and E. coli bacteria, and combinations thereof. Preferably, a polyvalent inactivated vaccine is provided for parenteral administration. Passive immunity is achieved in neonatal calves via immunization of pregnant cows prior to birth.
Abstract:
The invention relates to the field of coronaviruses and diagnosis, therapeutic use, and vaccines derived therefrom. The invention provides replicative coronaviruses and virus-like particles (VLPs) from which large parts of their genome are (at least functionally) deleted without abolishing their replicative capacities. The deletion preferably results in at least a functional deletion in that the corresponding gene is not or is only partly expressed wherein the resulting gene product is dysfunctional or at least functionally distinct from a corresponding wild-type gene product. One result seen with VLPs provided with deletions as provided herein is that the deleted VLP, albeit capable of replication in vitro and in vivo, are generally well attenuated, in that they do not cause disease in the target host, making them very suitable for therapeutic use, such as a delivery vehicle for genes and other cargo (wherein specific targeting may be provided as well when desired), and for use as a vaccine, being attenuated while carrying important immunogenic determinants that help elicit an immune response.
Abstract:
The present invention provides compositions for making a medicament and methods for the administration of a vaccine compositions for protection against human rotaviral disease without significant reactogenicity. Humannullrhesus reassortant rotavirus compositions were made which when were administered during the first 7 to about 10 days of life, provided a composition which was non-reactogenic followed by booster immunizations at 16 to 18 weeks or 14 to 20 weeks, up to 1 year of age. The immune response induced by the initial neonatal administration of the live rotavirus vaccine composition protects the infant from the reactogenicity of the composition when administered as a second dose at or after 2 months of age. Administration of thee immunogenic composition also is expected to ablate or significantly diminish the increase in the excess of imussusception observed 3 to 7 days following administration of the initial dose of rotavirus vaccine at about 2 to 4 months.
Abstract:
Methods and compostions related to the fields of bacteriology, immunology and gene therapy are provided. In general modified microflora for the delivery of vaccines, allergens and therapeutics to the mucosal surfaces of the respiratory tract are provided. In particular, the compositions and methods are directed at inducing an M-cell mediated immune response to pathogenic diseases. Specifically, methods of vaccine preparation, delivery and mucosal immunization using a Lactic Acid Bacteria (LAB), yeast and LAB that have been modified through fusion with E. coli to either present on its cell surface, or secrete, antigenic epitopes derived from pathogenic microorganisms and/or to secrete a therapeutic protein sequence are disclosed.
Abstract:
Defined serum-free, low protein media (LPKM), that supports 1) Vero cell growth for up to 20 passages, 2) Vero cell growth on microcarriers and 3) rotavirus production is provided. Maximum cell densities attained are 60-100% of that in serum-containing medium; the doubling time is equal to that for cells in serum containing medium. Rotavirus titers achieved in LPKM-1 are 50-100% of the serum-containing process. Finally, since LPKM-1 contains no animal-sourced proteins, the problems associated with the serum-containing rotavirus production process (i.e. lengthy wash steps before infection, potential introduction of adventitious agents and lot-to-lot variability) can be avoided; while maintaining nearly equivalent product titers.
Abstract:
Methods and compositions are disclosed for the dietary modulation of the immune system and gut microbial response in animals. Applicant has identified that oral administration of a supplemental spray dried plasma purified from animal serum can modulate serum IgG levels for treatment in such things as diminished immune capacity, intestinal microbial balance, autoimmune disorders, potentiation of vaccination protocols, and improvement of overall health and weight gain in animals, including humans.
Abstract:
The present invention relates to a colostrum and to a process for the preparation thereof to prevent rotavirus induced diarrhoea of G1 to G4, G5 and G6, G8 to G10. The process comprises in mixing the rotavirus specimens from infected children with an adjuvant to obtain water in oil emulsions. The virus singularly or the emulsion is inoculated into pregnant goats. The colostrum is collected from the immunized goats after delivery, dried and added to a carrier.
Abstract:
The present invention provides a process for producing immunoglobulin A in the milk of hyperimmunised ruminants using a 3 route immunisation protocol and uses for the resultant product. These products are useful in producing formulations useful for passive immunisation against selected pathogens, especially in preparations for food products and dietary preparations.
Abstract:
Methods and compositions are disclosed for modulating the immune system of animals. Applicant has identified that oral administration of immunoglobulins purified from animal serum can modulate serum IgG levels for treatment of autoimmune disorders, potentiation of vaccination protocols, and improvement of overall health and weight gain in animals, including humans.
