abstract：:Haemonchus contortus is an economically important parasite that survives the host defense system by modulating the immune response. Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is secreted by the parasite and the host responds by producing anti-enzyme antibodies. The enzyme inhibits complement cascade, an arm of t...
