Giemsa stained hemocytes of bacteria-infected 5th instar larvae of Antheraea assama were studied under 100X magnification by light microscopy. Bacterial infection was observed to induce distinct morphological changes in the various hemocyte types, including enlarged or swollen cells, highly vacuolated cytoplasm, severe nuclear fragmentation, loss of cytoplasmic compactness or cytoplasmic lysis, blebbing of plasma membrane or completely lysed plasma membrane, and sometimes aggregation of hemocytes to one another leading to encapsulation of the bacterial products
