The effect of created hemolymph apoptosis on WSSV Gama-vaccinated shrimp, Litopenaeus vannamei in WSSV disease control

White spot syndrome virus (WSSV) is the causative agent responsible for huge-shrimp viral epidemics in shrimp farms throughout the world. Our study was aimed to determine the effect of WSSV Gamma-vaccinated Litopenaeus vannamei on the occurrence of apoptosis. One thousand and twenty PL15 were randomly distributed among 2 treatments and two control groups. Gama-Vaccinated shrimp and non-Gamma-vaccinated ones were our treated and untreated groups. Based on our results significant differences (p<0.05) were observed in survival percent between vaccinated-exposed group (82.33 +/- 2.51) and non-vaccinated exposed group (26.00 +/- 10.00). It is concluded that apoptosis can be a helpful process in enhancing the immune response in shrimp especially against WSSV.
