    Abstract:
    Lymphocystis disease of the gilthead seabream, Sparus aurata from the south Atlantic coasts of Spain was studied using various cytochemical methods for nucleic acids, proteins, carbohydrates and lipids. In lymphocystis infected cells, cytoplasm and nucleoli contained RNA. DNA was restricted to the periphery of the nucleus and within the intracytoplasmatic inclusions. During the development of infected cells, proteins rich in different aminoacids were observed in the granular cytoplasm, nucleus/nucleoli, intracytoplasm inclusions and hyaline capsule. Some glycogen was observed in the cytoplasm of these cells. The intracytoplasm inclusions and the hyaline capsule also contain hydrophilic lipids, being noticeable the presence of proteins containing S-S groups. Sulphated sialoglycoproteins and glycolipids and/or phospholipids were also components of the hyaline capsule.
