Enhancement of immune response and resistance against Vibrio parahaemolyticus in kuruma shrimp (Marsupenaeus japonicus) by dietary supplementation of β-1,4-mannobiose

Supplementation of prebiotic carbohydrates can act as a potent immunomodulator and have the efficacy to induce immune-related genes which are involved in host defense. Pure β-1,4-mannobiose (MNB) showed activation of prophenoloxidase system of shrimp hemocytes in vitro. The resistance of kuruma shrimp Marsupenaeus japonicus against Vibrio parahaemolyticus was examined after the shrimp were fed with 0 (control), 0.02, 0.2, and 2% MNB supplemented diets. The results showed significantly higher survival rates in MNB supplemented shrimp than those of the control one from 2 to 12 days post challenge. In another experiment, the hemocyte count, ROS production, phagocytic, phenoloxidase and bactericidal activities, and expression of immune-related genes were investigated in the control and MNB supplemented groups at day 1, 4, 6, 8 and 11 of the feeding. These immune parameters were significantly enhanced in MNB supplemented groups. Furthermore, the gene expression analysis showed that transcripts of lysozyme, crustin, penaeidin and TNF were significantly up-regulated in hemolymph, lymphoid organs and intestines of MNB treated shrimp. Overall, the results provided evidence that MNB supplementation could improve the immune response and increase shrimp resistance against V. parahaemolyticus infection.
