Thus,
we have studied the inulin effects on the gilthead seabream (Sparus aurata L.) innate immune
response both in vitro and in vivo. For the in vitro study,head-kidney leucocytes were incubated
with inulin (ranging from 0 to 1000 mg ml1) for 30, 90, 180 and 300 min and 24 h and
any effect was observed on leucocyte viability or the main innate cellular immune responses
(leucocyte peroxidase, phagocytic, respiratory burst and natural cytotoxic activities).
