摘要:
The present invention provides for a method of reducing the reactogenicity of live attentuated bacterial vaccines by deleting at least a portion (e.g., the TLR-5 stimulating domain of a flagellin protein) of at least one of the bacterial genes that encodes a flagellin from the bacterium genome. These vaccines are directed against enteric or non-enteric flagellin-producing bacteria. A particular embodiment provides for a live attenuated cholera vaccine having reduced reactogenicity.
摘要:
Certain autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, and systemic lupus erythematosus may be prevented or attenuated by in vivo treatment with a complement-fixing anti-Leu3 (CD4) antibody that is cytotoxic to Leu3 (CD4) phenotype T cells.
摘要:
The present invention provides methods and compositions for production of gram-negative bacterial mutants that are defective in intestinal colonization capacity and sensitive to infection by bacteriophage P1. Thus the present invention provides immunogenic compositions for the prevention or attenuation of food- and water-borne illnesses associated with ingestion of bacteria such as enterohemorrhagic Escherichia coli.
