Abstract

This study intended to find out specific proteins from different organs of Clonorchis sinensis. Crude extract, organ-specific antigens and excretory-secretory (ES) antigen were analyzed by immunoblot with infected human sera. The bands of 7- and 17-kDa were main component of intestinal fluid and ES protein but commonly found in all organ-specific antigens. The protein of 17 kDa was observed from ES antigen, intestinal fluid, eggs and sperms, 26- and 28-kDa bands were from the uterus, vitellaria, and ovary, and 34-, 37-, 43- and 50-kDa bands were mainly from the testis and sperms. Serum of mice immunized with sperms reacted to the 50-kDa band by immunoblotting. Immunohistochemical staining with the immune serum showed a positive reaction exclusively at the seminal receptacle. The present results showed that the 7-kDa protein is a common antigen of every part or organ of C. sinensis, but different organs express their specific antigenic protein bands.
