Abstract
The causative agent of white spot
syndrome (WSS) has been identified to be
white spot syndrome virus (WSSV). WSSV
is an important pathogen that causes a great
impact on the shrimp culture industry. The in
vitro propagation of WSSV in the primary
culture of shrimp hemocyte had been
established successfully in this study. Under
electron microscopy, we not only confirmed
our result, but also we found one WSSV
mutant which formed a virogenic stroma in
cytoplasm. The cytoplasm of infected cells
with virogenic stroma showed the
degenerated phenomena: degraded organelles
and vacuolation, but their nuclei were more
or less in normal shape. The hyaline
hematocytes are the highest WSSV
susceptibility cells, followed by
semigranulocytes, and then granulocytes. The
mutant was also confirmed by the electron
microscopic observation of lymphoid organ
and could be found in all kinds of lymphoid
cells.
