Malaria infection (Plasmodium iophurae): changes in free amino acids.

The course of infection of the avian malaria Plasmodium lophurae in the duckling is characterized by striking increase in the intraerythrocytic free amino acid pool. The quality and quantity of this change result from the presence of the parasite and for the most part reflect the free amino acid pool of the growing plasmodium. No significant changes in the free amino acids in plasma were noted during infection.
