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.
