Abstract

Vibrio alginolyticus infection of Penaeus monodon was examined histopathologically. Hemocyte responses to the bacteria comprised hemocyte aggregation with necrotic core, infiltration of free hemocytes, and hemocyte encapsulation. However, there was melanization in association with the hemocyte encapsulation. The pronounced parenchymal lesions occurred in the gill, antennal gland, lymphoid organ, and hepatopancreas. In the most serious cases, the sick prawns exhibited septicemia and decreased in numbers of free hemocytes.
