Furthermore, given the high propensity of this variant to disseminate to bone marrow and peripheral blood, examination of peripheral blood should be performed to look for atypical lymphocytes, especially rare, large lymphocytes with basophilic
cytoplasm and fine vacuoles.
Digestive tubules in all mussel species examined were lined by two types of epithelial cells: dark-staining basophilic
cells (typically triangular in cross section) and light-staining, columnar digestive cells (Fig.
Although no etiology was detected for the basophilic
inclusions observed in the digestive gland of some oysters from Watt Bay and Port Eliza N.
The mucous cells were mostly basophilic
as they were in M.
Abundant cells containing pan-nuclear variably eosinophilic to basophilic
inclusions were present in all but the hybrid falcons.
These were roughly spheroidal cells of approximately 5 [micro]m in diameter, deep basophilic
nuclei and a high nucleocitoplasmic quotient.
Microscopically, multifocal hepatic and splenic necrosis accompanied by cells containing pan-nuclear basophilic
inclusions were consistently seen in all birds.
The exception was the rectal area--the only region where a cell type was found with very fine basophilic
granules and where the number of mucus cells and cells with acidophilic granules was reduced.
Tumor cells can be polygonal, oval, or spindle-shaped, and they contain variable amounts of granular, slightly basophilic
Nonspecific red blood cell abnormalities can be present, such as anisocytosis, poikilocytosis, anisochromia, basophilic
stippling, schistocytes, and erythrocytes that are poorly hemoglobinized.
The granulocytes contained numerous basophilic
or refringent cytoplasmic granules and had small nuclei, which often showed the oval or eccentric shapes.
Several histiocytes contained dense intracellular basophilic
to targetoid inclusions and appeared to be typical MG bodies.
