Estimating the term…
A vaccine, comprising as antigen, at least a part of the cell of strains of Streptococcus sanguis having a high pathogenic potential and capable of decomposing raffinose and mellibiose, in association with a pharmaceutically acceptable carrier or excipient. Preferably, the antigen is derived from the pili-like structures on the surface layer of the cells. Antibodies produced by immunizing a mammal with said antigen to produce the corresponding antibodies in the body of said mammal and recovering the resultant antibodies from the mammal. A pharmaceutical composition, comprising as active ingredient said antibodies, in association with a pharmaceutically acceptable carrier or excipient. Said vaccine, antibodies and antibody-containing composition may be used for treating human and animal diseases caused or aggravated by said microorganisms such as MCLS. Preferably, the composition comprises antibodies produced by the use of antigen(s) derived from the pili-like structures, in association with a carrier or excipient suitable for oral administration. The preferred composition may be directly and safely administered to the oral cavity of humans and animals to prevent or at least inhibit the infection of the virullent strains with good results.
A vaccine for the treatment of the microorganisms MCLS-type Streptococcus sanguis in the oral cavity of an animal subject, said microorganism having a high pathogenic potential and capable of decomposing raffinose and mellibiose, which comprises as active ingredient or effective amount of an antigen derived from a member selected from at least a part of the cell of said microorganism and culture thereof, and a pharmaceutically acceptable carrier.
A process for preparing antibodies for treating microorganisms of the MCLS-type Streptococcus sanguis in the oral cavity of an animal subject, said microorganism having a high pathogenic potential and capable of decomposing raffinose and mellibiose, which comprises immunizing a mammal with an effective amount of an antigen derived from a member selected from at least a part of the cells of said microorganism and culture thereof to produce the corresponding antibodies in the body of said mammal and recovering the resultant antibodies from said mammal.
A composition for the treatment of the microorganisms of the MCLS-type Streptococcus sanguis having a high pathogenic potential and capable of decomposing raffinose and millibiose, which comprises as active ingredient an effective amount of antibodies produced by immunizing a mammal with an effective amount of at least one antigen derived from a member selected from at least a part of the cell of said microorganisms and culture thereof to produce the corresponding antibodies in the body of said mammal recovering the resultant antibodies from said mammal, in association with a pharmaceutically acceptable carrier or excipient.
The composition of claim 8, wherein said antigen used to produce the antibodies at least one antigen is derived from the pili-like structures on the surface layer of the cell and said carrier or excipient is suitable for oral administration.
