Feasibility study of white spot syndrome virus vaccine with gamma radiation
The study of effect white spot syndrome virus(WSSV) attenuated vaccine that produced with gamma radiation on shrimp Litopenaeus vannamei carried out by imprinted 14000 PL from Kolahi hatchery in Hormozgan province. The shrimp divided to 3 groups as mentioned in table 2-1. The first group exposed to WSSV vaccine. The second group exposed to WSSV vaccine and then exposed to WSSV and the third did not exposed to vaccine and WSSV and named control positive. The experiment conducted 40 days and the shrimp cultured in standard trail. The result showed the shrimp exposed to vaccine and then exposed to WSSV has 76% and 61% higher survival rate after 35 days and 45 days respectively. The mortality rate also exhibited24% and 39% in both group respectively. The mean value of total hemocyte count and total protein plasma measuring with ANNOVA and LSD examination in group vaccinated and without vaccinate in exposing and injecting group showed no statistical differentiation (P>0.05) while the total heamocyte count and total protein plasma showed statistical differentiation (P.<0.05) between both groups. The result from histopathological examinations showed the cowdry type a inclusion bodies in all organ and tissue exhibited and the group vaccinated showed lower inclusion bodies with comparing without vaccinated.
