  • Cloned Babesia DNA
    Patent number: 5518916
    Abstract: The subject invention concerns the identification of novel merozoite surface proteins of Babesia bovis. Also disclosed are monoclonal antibodies to these proteins as well as genes which encode for the proteins. The invention further concerns the use of the novel proteins, recombinant DNA clones, and monoclonal antibodies in the detection, treatment, and prophylaxis of babesiosis.
    Type: Grant
    Filed: November 21, 1994
    Date of Patent: May 21, 1996
    Assignee: The United States of America as represented by the Secratary of Agriculture
    Inventors: Terry F. McElwain, Travis C. McGuire, Douglas P. Jasmer, David W. Reduker, deceased, Will L. Goff, David Stiller
  • Immunization against babesiosis using purified surface antigens of Babesia bigemina and similar immunogens
    Patent number: 5422428
    Abstract: Antigenic surface proteins from the intraerythrocytic merozoite stage of Babesia bigemina have been isolated using cell fusions and monoclonal antibodies produced thereby. The gene encoding a 58 kD surface protein has been identified and the DNA sequence determined and compared with sequences of other known merozoite proteins. Immunization of mammals, such as bovines, with purified isolates induces an immunological response that is effective to reduce pathological effects of babesiosis induced by Babesia bigemina. Diagnostic kits using monoclonal antibodies and antigenic surface proteins of Babesia bigemina are also disclosed.
    Type: Grant

    Date of Patent: June 6, 1995
    Assignee: Washington State University
    Inventors: Travis C. McGuire, Terry F. McElwain, Lance E. Perryman, William C. Davis
  • Cloning of the Babesia bovis 60 KD antigen
