Effect of gastrointestinal parasite infection in calves on the preparation of carrier erythrocyte ghosts and on erythrocyte survival.
Calves were inoculated with helminths to induce a severe anemia. Increased erythrocyte mean cell volume caused by acute parasitism made erythrocytes more resistant to osmotic stress as reflected in the percentage of encapsulation parameters. Preparation of resealed carrier erythrocytes before and during parasitosis was studied. Low percentage of encapsulation of the marker [14C]sucrose could be corrected by extended dialysis time. Typically, 40% encapsulation was found in erythrocytes from healthy calves, whereas only 20% encapsulation was found for erythrocytes from helminth-infected animals.
