Abstract

Haemagglutination assay (HA), humoral-mediated specific immune response and
alternative pathway of complement-mediated haemolysis (APCH50) were performed
to evaluate the immunological responses of the synthetic hormone drug ovaprim
in Heteropneustes fossilis. It was found that ovaprim suppresses the haemagglutinin
as well as the specific antibody titres of the catfish sera against rabbit
erythrocytes (RaRBCs) and bovine serum albumin (BSA) antigen while combination
with |3-glucan restored its normal activity indicating its immunomodulatory effect.
Furthermore, APCH50 unit of fish sera was remarkably decreased by ovaprim
treatment. Anti-ovaprim antibody could not be detected in serum of the treated
catfish.
