KEY WORDS: Orthonectida, plasmodium, phagocytosis, pinocytosis.

ABSTRACT: The parasite plasmodium of orthonectid Inthoshia linei is covered with 2 distinct membranes. Plasmodium bears microvilli in some regions. A highly developed tubular network resembling smooth endoplasmic reticulum is considered to be a part of a permanent pinocytotic complex. Phagocytosis and pinocytosis both are supposed to be the mechanisms of plasmodium feeding.
