摘要: In this study, postlarvae of the fleshy shrimp Fenneropenaeus chinensis "Huanghai No. 2" (a new shrimp variety bred in China) were fed with white spot syndrome virus (WSSV)-toxic bait with amount of 25% of the total shrimp body weight and were evaluated WSSV loads at different postinfection periods (i.e. early, peak and late periods). A total of 83 of 4,424 shrimp (1.88%) survived at the end of the experiment, which lasted 358 h, 662 h, and 232 h in 3 ponds, respectively. The WSSV loads were 8.8 x 10(4)-1.5 x 10(5), 4.4 x 10(5)-1.2 x 10(6), and 8.5 x 10(5)-4.6 x 10(6) copies/ng DNA, respectively, averaging 9.5 x 10(5) copies per nanograms DNA of all sampled shrimp (n = 229). The viral loads in the shrimp that died during the late postinfection period were significantly higher than in those shrimp that died during the early and peak periods (P < 0.01). The viral load in surviving shrimp was 2.2 x 10(5) = 44) copies/fig DNA. Among the surviving shrimp, 18.2% (n = 8) had a viral load greater than 1.0 x 10(4) copies/ng DNA and 52.3% = 23) had less than 100 copies/ng DNA. Based on these result, the range of 7.0 x 10(4)-10(7) copies/ng DNA is suggested to be the lethal amount for shrimp death caused by WSSV. These results could be an important reference in an advance warning of a WSSV outbreak in the culture process of these shrimp, and could provide valuable information in further selective breeding of WSSV-tolerant or -resistant varieties of F. chinensis.
