3.2.4.Maternal transmission of immunity to white spot syndrome associated virus (WSSV) in shrimp (Penaeus monodon)

Reports indicate that β-1,3-1,6-glucan, derived from bakers' yeast Saccharomyces cerevisiae, was able to protect spawners from white spot syndrome associated virus (WSSV), and the protection could be passed on to hatchlings via maternal transmission of immunity. The study suggested that the application of glucan might lead to a slight enhancement of disease resistance in spawners. Challenge results showed a significant increase in relative percent survival for larvae derived from groups of glucan-injected spawners compared to those derived from groups of untreated spawners.
