CYTOMEGALOVIRUS IN THE PAROTID-GLAND OF A SLOW LORIS, NYCTECIBUS COUCANG

Sporadic enlarged cells with both nuclear and cytoplasmic viruses were found in the intra-lobular ducts of the parotid salivary gland of an adult female slow loris; these ducts are homologous to striated ducts in the salivary glands of other primates. The duct cell nuclei contain ed reticular inclusions and virions in all stages of development. Cyto plasmic virions were, in almost every case, confined to vacuoles; only a very few were free in the cytosol. The viruses conformed in ultrast ructure to that of cytomegaloviruses described in other species. This may be the first observation by electron microscopy of in situ cytomeg aloviruses in the salivary glands of a nonhuman primate.
