| Outline of Final Research Achievements |
In this study, Heat shock protein 90 (Hsp90) in Babesia gibsoni, a blood protozoa in dogs, was analyzed. The Babesia gibsoni heat shock protein 90 (BgHsp90) gene was cloned and sequenced. Moreover, anti recombinant BgHsp90 antibody was developed. Additionally, the expression of BgHsp90 was observed. As results, it was shown that BgHsp90 might contribute the proliferation of the parasites, and that the expression of BgHsp90 would be elevated when the parasites were exposed to the high temperature. Meanwhile, Hsp90 inhibitors could suppress the proliferation of B. gibsoni in vitro. This result suggested that the BgHsp90 should be one of the drug targets for the treatment of canine babesiosis.
