Abstract
Haemonchus (H.) contortus is a blood feeding gastrointestinal nematode, and is considered one of the major threats for goat health and production globally. Crude somatic antigens (CSA) have been reported as sources of immunogens and provide better level of immunity against gastrointestinal nematodes. The present study aimed to quantify CSA of H. contortus worms (n=25) of both sexes followed by isolation of peptides through Sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and their characterization. The triturate contained proteins having concentration of 1.3mg/ml as measured through Bradford assay. Seven different bands were appeared on gel ranging from 35KDa to 170KDa. The future prospects may include identification of the immunogenic peptides which can be used as vaccine candidates against H. contortus.
