“…Lee and Shiau [40] first reported that intracellular superoxide anion production of the haemocytes in P. monodon fed diets containing ascorbate supplements was approximately 1.27e2.24 times higher than that of shrimp fed unsupplemented diets. It has been demonstrated that O 2 ÿ generation by shrimp P. stylirostris [14] or oyster Crassostrea gigas [48] haemocytes depended on the presence of NADPH oxidase enzyme, a cell membrane-bound enzyme. In the present study, superoxide anion production by the haemocytes in groups fed with MBM or PBM diets was not significantly different from that of the control.…”

“…Phagocytised (Planococcus citraeus) and symbiotic (Vibrio ssp.) bacteria also increased the level of apoptotic hemocytes in C. gigas and this have been associated with oxidative damage [24,25]. The signaling pathways involved in apoptosis of mollusks share significant molecular similarity with those observed in vertebrates (Fig.…”

“…In bivalves, the stimulation of the Mediterranean mussel with Pathogen-associated molecular patterns (PAMPs) [109] or the infection with several species of Vibrio in the Pacific oyster [103,147], in the carpet shell clam (R. decussatus) [82] and in the king scallop (P. maximus) [95] induced the expression of initiator and executioner caspases. Symbiotic and phagocytized bacteria can also increase the level of apoptosis, as observed in hemocytes in C. gigas [125].
