Application Number:	08/255,557
Patent Claims:	1. A method of treating an individual infected with rabies virus and clearing said rabies virus from infected cells of said individual's central nervous system comprising administering a therapeutically effective amount of a pharmaceutical composition comprising: a) a single species of antibodies; and b) a pharmaceutically acceptable carrier or diluent; wherein: a) said antibodies each consist of i) constant regions from a human antibody, and ii) a complete variable region wherein all CDRs are complete CDRs of MAb 1112-1 and framework regions are framework sequences of a human antibody and b) said antibodies are capable of neutralizing rabies virus infection in an individual exposed to and infected by rabies virus and clearing rabies virus from infected cells of said individual's central nervous system when said antibodies are administered to said individual after said individual is exposed to and infected by said virus. 2. A method of treating an animal infected with rabies virus and clearing said rabies virus from infected cells of said animal's central nervous system comprising administering a therapeutically effective amount of a pharmaceutical composition comprising a) a therapeutically effective amount of a single species of antibodies; and b) a pharmaceutically acceptable carrier or diluent; wherein: a) said antibodies consist of constant regions from non-murine antibodies and variable regions from MAb 1112-1; and b) said antibodies are capable of neutralizing rabies virus infection in an animal infected by rabies virus and clearing rabies virus from infected cells of said animal's central nervous system when said antibodies are administered to said animal after said animal is exposed to and infected by said virus. 3. The method of claim 2 wherein said constant regions are human constant regions. 4. The method of claim 1 wherein: a) constant regions of said antibodies are human constant regions; b) framework sequences of said antibodies are complete framework sequences of a human antibody; and c) all CDRs of said antibodies are complete CDRs of MAb 1112-1. 5. The method of claim 1 further comprising the step of administering a rabies vaccine. 6. A method of treating an animal infected with rabies comprising administering a therapeutically effective amount of a pharmaceutical composition comprising: a) a single species of antibodies; and b) a pharmaceutically acceptable carrier or diluent; wherein said antibodies are MAb 1112-1. 7. The method of claim 6 further comprising the step of administering a rabies vaccine. 8. A pharmaceutical composition for the treatment of an individual infected with rabies comprising: a) a therapeutically effective amount of a single species of antibodies; and b) a pharmaceutically acceptable carrier or diluent; wherein: a) said antibodies each consist of i) constant regions from a human antibody, and ii) a complete variable region wherein all CDRs are complete CDRs of MAb 1112-1 and framework regions are framework sequences of a human antibody and b) said antibodies are capable of neutralizing rabies virus infection in an animal exposed to and infected by rabies virus and clearing rabies virus from infected cells of said animal's central nervous system when said antibodies are administered to said animal after said animal is exposed to and infected by said virus. 9. A pharmaceutical composition for the treatment of an individual infected with rabies comprising: a) a therapeutically effective amount of a single species of antibodies; and b) a pharmaceutically acceptable carrier or diluent; wherein: a) said antibodies consist of constant regions from non-murine antibodies and variable regions from MAb 1112-1; and b) said antibodies are capable of neutralizing rabies virus infection in an animal exposed to and infected by rabies virus and clearing rabies virus from infected cells of said animal's central nervous system when said antibodies are administered to said animal after said animal is exposed to and infected by said virus. 10. The pharmaceutical composition of claim 9 wherein said constant regions are human constant regions. 11. The pharmaceutical composition of claim 1 wherein: a) constant regions of said antibodies are human constant regions; b) framework sequences of said antibodies are complete framework sequences of a human antibody; and c) all CDRs of said antibodies are complete CDRs of MAb 1112-1. 12. The pharmaceutical composition of claim 1 further comprising a rabies vaccine.
