Extract

Lipid material occurs in the oocysts of Plasmodium in the form of small Sudano-phil granules, which appear to increase in size with the growth of the parasite. A diffuse Sudanophil material also appears at a later stage.

Phospholipid occurs at a certain stage of the oocyst, but later disappears altogether. It appears more quickly in some oocysts than in the others, found in the same infected gut.

The pre-erythrocytic schizonts of P. cynomolgi are found to contain abundant lipid material.

The erythrocytic stages of Plasmodium and Hepatocystis cannot be stained with the Sudan dyes, but the gametocytes of Hepatozoon infecting the blood corpuscles of the vertebrate hosts are found to contain abundant Sudanophil material.

Sudanophil material can be detected in the unsporulated oocysts of Eimeria stiedae, but not in the sporulated ones.
