摘要:
Infectious laryngotracheitis virus (ILTV) and egg drop syndrome virus (EDS) production are currently cultivated in either primary cell cultures or in chicken embryos. These production practices are both costly and difficult. Until now no continuous cell line has been identified which is capable of supporting either ILTV or EDS replication. This invention involves the discovery that a chemically transformed chicken hepatocyte derived cell line is capable of efficiently supporting replication of both ILTV and EDS. Titers of virus harvested from cell culture are sufficient to allow conversion of production from chicken embryo or primary cell culture to continuous cell culture methods.
摘要:
The present invention is concerned with live combined vaccines for immunizing poultry comprising at least two different viruses, wherein at least one of the viruses is an infectious bronchitis virus showing the property of spontaneously hemagglutinating chicken erythrocytes.
摘要:
A method for the treatment of cancer comprising administration of a therapeutically effective amount of an intralesional chemoablative pharmaceutical composition, or variant of said composition, in combination with a therapeutically effective amount of a systemic immunomodulatory anticancer agent. A further method for the treatment of cancer comprising administration of a therapeutically effective amount of an intralesional chemoablative pharmaceutical composition, or variant of said composition, in combination with a therapeutically effective amount of a systemic targeted anticancer agent. The present invention is further directed to pharmaceutical compositions for treatment of cancer. The intralesional chemoablative pharmaceutical composition can comprise an IL chemoablative agent comprising primarily a halogenated xanthene.

摘要:
Disclosed are therapeutic compositions and methods for inducing an immune response to herpes simplex virus type 2 (HSV-2). More particularly, the invention relates to a method for inducing an immune response in a subject by introducing and expressing an HSV gD2-encoding DNA vaccine.
摘要:
The present invention relates to immortalised chicken embryo fibroblasts, to cell cultures comprising such immortalised cells, to vaccines comprising such cells, to methods for the propagation of avian viruses on such cells, and to methods for the preparation of such cells and such vaccines.
摘要:
The invention provides a vaccine composition comprising an antigen component and an adjuvant component, wherein the adjuvant component comprises a P-class immunostimulatory oligonucleotide and either a combination of a saponin and a sterol; or an oily phase comprising an oil and, optionally, one or more emulsifiers, said oily phase comprising 2-20% v/v of the vaccine composition, wherein said antigen component is an EHV antigen or a Leishmania antigen.
摘要:
The invention provides a method of protecting a bovine susceptible to Bibersteinia trehalosi , the method comprising administering to said bovine an effective amount of a vaccine comprising a Mannheimia haemolytica antigen, and further comprising one or more of Infectious Bovine Rhinotracheitis Virus, Bovine Viral Diarrhea Virus, Parainfluenza-3 Virus, and Bovine Respiratory Syncytial Virus.
摘要:
The anti-pathogen vaccine of the present invention is produced in recombinant bacteria and/or transgenic plants and then administered through standard vaccine introduction method or through the oral administration. A DNA sequence encoding for the expression of an antigen of a pathogen is isolated and ligated to a promoter which can regulate the production of the surface antigen in a bacterial or transgenic plant. Preferably, a foreign gene is expressed in a portion of the plant or bacteria, and all or part of the antigen expressing plant or bacteria used for vaccine administration. In a preferred procedure, the vaccine is administered through the consumption of the edible plant as food, or the bacteria administered orally. The present invention also provides a method of using genetically modified microorganisms generally recognized to be edible and/or harmless to animals or humans when ingested, such as lactic acid bacteria, including Lactococcus lactis strains, as oral vaccines. In one embodiment, Lactococcus lactis expressing the avian influenza HA gene can be used as an oral vaccine for protection against H5N1 virus infection.
