Abstract

In this study, the gene encoding Babesia equi merozoite antigen-2 was inserted into a baculovirus transfer vector, and a recombinant virus expressing B. equi merozoite antigen-2 was isolated. Two B. equi merozoite antigen-2-related recombinant baculovirus-expressed peptides of 25 and 30 kDa were detected with a murine anti serum against B. equi merozoite antigen-2; these corresponded to the native B. equi merozoite antigen-2 and were secreted into the supernatants of insect cell cultures. Recombinant B. equi merozoite antigen-2 was not effected by tunicamycin treatment, indicating that B. equi merozoite antigen-2 was not glycosylated. The potential of recombinant B. equi merozoite antigen-2 for use in the ELISA was evaluated by measuring the antibody response to B. equi merozoite antigen-2 in horses experimentally infected with B. equi.
