[Culex pipiens fatigans: labeling of tissues of normal and infected (Plasmodium cathemerium) females after feeding on tritiated amino acids (author's transl)].
Normal and infected Culex females were fed 11 different amino acids. These substances were labeled with tritium and each was given separately in glucose solution. After the uptake the marker appears first in crop, cardia and midgut. Later on the other tissues get labeled more or less. It seems that the labeling follows a characteristic pattern for each amino acid. Essential amino acids are taken up intensively; for example leucine not only in the midgut epithelium but also in the ovary and the fat body. There is nearly no uptake of the non-essential amino acids alanine, glutamic acid and DOPA by the tissues of both groups of females. These amino acids are only seen in the midgut area and not in the other tissues. In infected mosquitos the uptake of the essential acid, phenylalanine, corresponds only to that of a non-essential amino acid.
