Table 13.1. Summary of the protection induced against Haemonchus contortus using proteins purified from the intestine. 

This fraction was termed Haemonchus galactose-containing glycoprotein complex (H-gal-GP). The microvillar surface of the intestinal cells of worms retrieved from vaccinated lambs was coated with sheep immunoglobulin and protection observed, over a series of trials, was correlated with systemic antibody titre (Smith et al., 1999).
