Blood was collected from grazing lambs from lines of Romney sheep selected on the basis of low (resistant line) or high (susceptible line) faecal nematode egg count. Leucocytes were prepared by osmotic lysis of erythrocytes and then subjected to centrifugation on discontinuous Percoll density gradients. Lambs from the resistant line had significantly more hypodense eosinophils than did lambs in the susceptible line.
