Juvenile American white shrimp (Litopenaeus vannamei) were immersed in aerated beta-glucan and sulphated polysaccharide solutions for 1, 3 and 6 h. Superoxide anion and SOD activity in haemocytes and muscle were investigated to evaluate whether beta-glucan and sulphated polysaccharide induce any immunostimulatory activity. Haemocytes and muscle showed different levels of superoxide anion generation and SOD activity (2.0 and 14 times that of control, respectively) when shrimp were immersed for 6…

Effects of salinity on the clam Chamelea gallina haemocytes. Part II: Superoxide dismutase response

The effects of different salinity levels on functional responses of Chamelea gallina haemocytes were evaluated and confirmed the destabilizing effect of 40‰ salinity on haemocyte functionality, while to 28‰ exposure, data don’t confirm its stressful action as instead stated by results of Part I.

Comparative study of the intracellular superoxide anion production in different penaeid species through the NBT-reduction assay

Laminarin (β-1,3-glucans – 2 mg mL−1) was the most potent cell activator for the haemocytes of all three penaeids and it is recommended to routinely evaluate shrimp respiratory burst.

Enhancement of superoxide dismutase and catalase activity in juvenile brown shrimp, Farfantepenaeus californiensis (Holmes, 1900), fed β-1.3 glucan vitamin E, and β-carotene and infected with white spot syndrome virus

The capacity of juvenile Farfantepenaeus californiensis fed β-1.3-glucan, vitamin E, or β-carotene to increase the antioxidant response before and after viral infection is demonstrated.

Reactive oxygen system plays an important role in shrimp Litopenaeus vannamei defense against Vibrio parahaemolyticus and WSSV infection.

The results suggest that lysozyme, the antioxidase system, and reactive oxygen species might play a crucial role in shrimp defense against bacterial and viral infection.

Effect of dietary β-1,3-glucan on the immune response of Litopenaeus vannamei exposed to nitrite-N

Considering dietary cost and immunostimulatory effects, the feeding schedule with 14 days BG–14 days control diet is more recommended, and significantly higher activities of haemolymph SOD was only seen in C + BG group.

Activation of prophenoloxidase, agglutinin and antibacterial activity in haemolymph of the black tiger prawn,Penaeus monodon, by immunostimulants

A lower antib bacterial activity was detected in samples treated with LPS after clotting (HLF), than in those treated before clotting, suggesting that LPS was involved in mechanisms for both clotting and for antibacterial activity.

Effect of hypoxic stress on the immune response and the resistance to vibriosis of the shrimpPenaeus stylirostris

The variations of immunological parameters, except for the PO activity, seem to be consistent with the in vivoresponse against the pathogenic Vibrio in shrimp exposed to severe hypoxia.

Vibriosis resistance induced by glucan treatment in tiger shrimp (Penaeus monodon)

It appears that beta-glucan is a short-term immunostimulant for shrimp and enhanced the phenoloxidase activity in shrimp hemocytes in vitro.

Haematological and phenoloxidase activity changes in the shrimpPenaeus stylirostrisin relation with the moult cycle: protection against vibriosis

Changes in the total and differential haemocyte counts during the moult cycle of the shrimp, Penaeus stylirostris, and variations of selected parameters seem to be consistent with the in vivo response against the highly pathogenic Vibrio AM23.

Analyses of Hemolymph Immunoparameters in Kuruma Shrimp Infected with Penaeid Rod-shaped DNA Virus

Results indicate that PG can mitigate physiological changes during PRDV infection and survival rates after 10 days of the challenge were 70% and 35% for the PG-fed group and control group, respectively.

Effects of LPS injection on circulating haemocytes in crustaceansin vivo

The results show that LPS causes a decrease in the number of circulating haemocytes as a generalized response in crustaceans, but the time to reach maximum haemocytopenia and the extent of cell loss are species-specific and not affected by temperature.
