The microsporidian, Enterocytozoon hepatopenaei (EHP) is an intracellular parasite
that has become a critical threat to the shrimp farming, Litopenaeus vannamei in
Southeast Asia. This parasite replicate in the hepatopancrease and midgut, and
infected shrimp exhibit reduce feeding and severely retarded growth with variation of
size. In this study, hepatopancrease sample from 30 individual of shrimp L. vannamei
from Terengganu area that suspected infected with EHP disease were analyzed by
using histology technique. The results showed that all the shrimp examined were
infected with EHP. Infected shrimp showing basophilic inclusions in hepatopancrease
tubule epithelial cells. Midgut epithelial cells were also infected. All the samples
showed the presence of microsporidian spores in cytoplasm of hepatopancreatic
tubule epithelial cells.
