白點病毒在草蝦初期蝦苗感染之研究(II)
- 計畫編號：99農科-10.3.1-水-A4(3)
- 年度：2010
- 領域：漁業科技研發領域
- 主持人：劉冠甫
白點病毒在不同環境因子下對草蝦的無節幼蟲的感染情況，會隨著因子的變化而有不同的感染等級產生，在不同硝酸-氮濃度下對於草蝦的無節幼蟲都會感染，但不同硝酸-氮濃度會影響病毒在宿主體內的繁殖速度，在高濃度（25、50mg/l） 濃度下病毒的感染等級會隨著濃度升高而增加，在後期幼蟲期時的活存率上比較低濃度組（0、5 mg/l）濃度 與高濃度（25、50mg/l）組內無顯著差異，但組間有顯著差異。
銨-氮的濃度在急性半致死濃度（4.0 mg/l）下對於白點病毒感染無節幼蟲情形，會隨著銨-氮的濃度增加而提高病毒的感染等級。
研究報告摘要(英) WSSV under different environmental factors on grass shrimp nauplius of the infection, will change with factors have produced different levels of infection in different nitrate - N concentration, for the grass shrimp nauplius are affected, However, different nitrate - N concentration will affect the propagation of the virus in the host body speed, in high concentrations (25、50 mg / l) concentration level of virus infection will increase with the concentration in the post-larval survival rate when the relatively low concentrations (0、5 mg / l) concentration and high concentration (25、50 mg / l) no significant group differences, but significant differences between the groups. Ammonium - N concentrations in the acute lethal concentration (4.0 mg / l) for the white spot virus infection under the nauplius, it might be with the ammonium - N concentration and improve the level of virus infection.
