The next most abundant cell resembles
the heterophil of Campbell & Ellis
(2007); this cell is equivalent to the
fine eosinophilic granulocyte of Arnold
(2005). Heterophils were of similar
overall size to erythrocytes, but
round rather than elliptical. The cytoplasm
varied from neutral to distinctly
basophilic and was replete with indistinct,
irregular, slightly eosinophilic
granules. The nucleus varied clinally
from spherical to deeply segmented.
Ostensibly similar, the eosinophil or
coarse eosinophilic granulocyte (Arnold
2005) was the next most common
cell and differed from the heterophil in
having large and distinct cigar-shaped
granules that were prominently and
vividly eosinophilic
