Round, compact lesions in the digestive gland cells contain refractive elements staining slightly blue or red with Geimsa. Ultra-structurally, each lesion contains (a) dense cytoplasma, without mitochondria and with paracrystal-line inclusions, (b) enclosed regions with vacuolar cytoplasm, no mitochondria and two types of formation; one is opaque, the other a vacuole containing ribosomes, lamellar structures and peripheral ovoid particles. The nature and significance of these structures is not known. PY 1971 PD DEC SO Revue des Travaux de l'Institut des PĂȘches Maritimes SN 0035-2276 PU ISTPM VL 35 IS 4 BP 415 EP 418 ID 2238 ER EF
