Abnormal, large, possibly neoplastic cells from two Ostrea /urida have been successfully labeled with tritiated thymidine, and thus, for the first time, data are available for analyzing a presumptive invertebrate proliferative disorder. Large numbers of labeled atypical cells (AC) were uniformly distributed throughout the connective tissue (CT) underlying the gills,...
Beginning in the late 1960s and throughout the past decade, unusual, perhaps neoplastic, large cells with rather consistent characteristics were described in mussels, clams, and oysters from several bays in the United States and the United Kingdom. The large, characteristic cells are thought by many workers to be abnormal leukocytes...
The purpose of this report is to describe a large tumor complex that was found protruding into the pericardial cavity of a single Ostrea lurida from Yaquina Bay, Oregon.
A cellular proliferative disorder that superficially resembles mammalian leukemia has been found in several species of pelecypod mollusks from Yaquina Bay, Oreg. This paper reviews the history of the disease, its cytomorphological and histopathological characteristics, molluscan oncology, and cell renewal and describes current research on the neoplastic disease of bivalve...
