Area of Research Interests:

Theileria equi is one of the highly endemic disease of equids in the country. We have developed recombinant antigen based ELISA for diagnosis. In host-parasite interaction rhoptry protein plays a major role. These proteins are thought to participate in host-cell recognition and thereby enhances invasion of the parasite into the host red blood cell. Information on the rhoptry protein of B. equi is still lacking and is another priority area of research for development of a suitable vaccine. We are also interested to identify a drug target in this organism and design drug molecule by using bioinformatic tools.
