Figure 4From: Impacts of breed type and vaccination on Teladorsagia circumcincta infection in native sheep in Gran CanariaTotal worm burdens after challenge infection in two sheep breeds vaccinated against T. circumcincta. Worm burdens are shown of sheep (CHB, circles; CS, squares) challenged with 2000 T. circumcincta L3 three times per week for 4 weeks following immunization with an eight-protein cocktail in the context of Quil A (blue symbols) or with Quil A only (red symbols). The mean worm burden is shown ± SEM (n = 12 for CS vaccinated and CHB control and in CS control and CHB vaccinated where n = 11).Back to article page
