Abstract: 
The effects of the oral administration of heat-inactivated Lactobacillus delbru¨eckii
ssp. lactis and Bacillus subtilis, individually or combined, on gilthead seabream immune
responses were investigated both systemically and locally in the gut.
In a first experiment, seabream (65 g) were fed for 3 weeks different diets supplemented
with 1 107 CFU g 1 Lactobacillus, 1 107 CFU g 1 Bacillus, or 0.5 107 CFU g 1 Lactobacillus
plus 0.5 107 CFU g 1 Bacillus. Controls were fed non-supplemented diet. Six fish per
group were sampled at the end of the trial and some humoral and cellular systemic innate
immune parameters were evaluated. Feeding the mixture of the two killed bacteria species
significantly increased natural complement, serum peroxidase and phagocytic activities
compared with controls.
In a second experiment, juvenile seabream (13 g) were fed for 3 weeks the same experimental
diets and total serum IgM and numbers of gut IgMþ cells and acidophilic granulocytes
were evaluated. All these parameters were significantly higher in the multispecies
probiotic group compared to monospecies and control fed groups.
