Blood Cell Morphology of Rusa Deer (Cervus timorensis russa)

Abstract

Blood cells from direct blood smears of 10 males and 17 females rusa deer using micrometer were measured. Red blood cell showed anisocytosis. The range in diameter was 4.0-8.0 μm with an average of 5.2 μm. One or two Howell-Jolly bodies were found in differential count of normal rusa deer blood smears. Neutrophil ranged in size from 12-15 μm averaging 13.5 μm. They contained prominent pink granules and well-defined nuclear lobes. Eosinophil ranged in size from 12-16 μm averaging 14 μm. They contained numerous small, round red refractile granules of uniform size which nearly covered the light blue cytoplasm. Basophil ranged in size from 13-16 μm averaging 14.5 μm. Its nucleus was covered by blue-black granules. Lymphocyte ranged in size from 7-20 μm averaging 10.7 μm. Small lymphocyte was the major lymphocyte in rusa deer. Monocyte ranged in size from 14-18 μm averaging 16.0 μm. It is not a common cell in the blood smear of rusa deer. Odd lymphocyte is the large lymphocyte that is difficult to be distinguished from monocyte. Odd lymphocyte was found in only 37% of examined blood smear and 1-2% of white blood cell counted.
