  • Patent number: 5643737
    Abstract: 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.
