Abstract

Adenovirus-like particles associated with epithelial hyperplasias in dab, Limanda limanda (L.).

Abstract

Epithelial hyperplasia or papilloma patches on dabs were examined for virus by electron microscopy. In all 4 tumours examined, inclusions of virus-like particles were found in the nuclei of otherwise normal cells. The number of virus-like particles varied from between a few to 200 particles per section of nucleus. The particles were considered to be icosahedrons and measured about 80 nm from vertex to vertex. Their average diameter was approx. 70 nm. The non-homogeneously stained core was surrounded by a capsid about 7 nm thick. It is suggested that the particles are adenovirions or adenovirus-like virions.
