Patent number: 5643737Abstract: The present invention relates to a purified and isolated merozoite protein which is a specific indicator of infection by Babesia equi (B. equi) in horses. This protein contains a conserved region found in all strains of B. equi. It has a molecular weight of approximately 28 KDa and has been successfully purified and sequenced. The isolated and purified merozoite protein is used to prepare antibodies which can then be used in a competitive inhibition enzyme linked immunosorbent assay for the diagnosis of B. equi infection in horses.Type: GrantFiled: March 2, 1995Date of Patent: July 1, 1997Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Donald P. Knowles, Jr., Lance E. Perryman
