At the end of the procedure, modified ultrafiltration restores the haemoglobin and haematocrit to normal levels. The binding or release of oxygen results in conformational changes that alter the affinity of haemoglobin for oxygen. This proteinase was especially active against mucin, albumin and haemoglobin and, hence, may be important in parasite feeding. In the present study a seasonal nutritional stress was indicated by a decrease in both haemoglobin and ferritin in the control group.
