The growth characteristics of nonaxenic and axenic Oocystis borge and Chlorella sp.

对无菌和带菌的波吉卵囊藻和小球藻（Chlorella sp。

And RW pathogen material impact on promoting corruption, the result shows : RW promoting corruption in simulated conditions, the number of male live Meloidogyne incognita, the number of females and 10 days respectively reduction in the number of oocysts 61.31%, 48.51%, 49.22%; Pathogens in tobacco black shank (Phytophthora nicotiana Breda de Haan), cercospora leaf spot pathogen were lower 97.68% and 97.77%.

与RW促腐剂对病害病原物影响对比，结果显示：RW促腐剂在模拟条件下，使活体根结线虫雄虫数、雌虫数、卵囊数在10d内分别减少61.31%、48.51%、49.22%；使烤烟黑胫病病原菌(Phytophthora nicotiana Breda de Haan)、角斑病病原菌分别比对照减少97.68%、97.77%。

The melanotic encapsulation of oocysts is a specific immune defence mechanism against Plasmodium infection ,and is also a primary phenotype in the Plasmodium-refractory strain of An.gambiae.

卵囊黑化包被反应是按蚊抵御疟原虫感染的特异性免疫防御机制，也是抗性株冈比亚按蚊或不易感按蚊的最主要表型。

Prophenoloxidase is a key enzyme for mediating melanotic encapsulation of oocysts,which may be transformed into active phenoloxidase by limiting proteolysis.

而前酚氧化酶(Prophenoloxidase，PPO)是介导卵囊黑化包被反应的一种关键酶，活化后可催化酪氨酸羟基化为二羟基苯基丙氨酸，二羟基苯基丙氨酸和多巴胺可进一步氧化为具有活性的苯醌活性，苯醌即可介导蛋白交联并聚合成黑色素层固定、隔离或杀死入侵的病原体。

The water quality was more stability when the dominant species was mainly Oocystis borgei in it. Ammonia nitrogen and nitrite nitrogen in the experiment pond was lower than that of the control pond.

波吉卵囊藻为主的微藻群落控制的水质较稳定，实验池氨氮和亚硝酸盐氮浓度较对照池低。

The result showed that the average biomass of Oocystis borgei in the early, middle and late period of prawn culture was 98.02%, 78.89% and 45.12%, respectively of the total microalgae. As the dominant species, it lasted for about 77 days in the prawn pond.

结果表明：养殖前、中、后期，波吉卵囊藻平均生物量占浮游植物总生物量分别为98.02%、78.89%和45.12%，成为虾池中的绝对优势种；作为优势种的持续时间长达77d。

Oocystis borgei, which was selected from the prawn culture pond and expanded after 3-grade cuture, was artificially introduced into the culture system of Litopenaeus vannamei. The structure of microalgae community, the water quality, the factors that relate to the anti-disease ability of prawn and the growth of prawn were inspected to study the technology of microalage-ecology control to prevent shrimp diseases.

采用微藻三级扩大培养技术，将在对虾养殖池选育的波吉卵囊藻Oocysits borgei引入凡纳滨对虾Litopenaeus vannamei高位养殖池，并检测养殖环境中微藻群落结构、水质因子、对虾抗病力相关因子、对虾生长情况，研究了以微藻生态调控为主的对虾防病技术。

It is possible from the above investigations, AsSP1 and AsSP2 might be correlated with the plasmodial infeetion or the melanotie eneapsulation of P.

结论AsSP1和AsSP2很可能与疟原虫感染或约氏疟原虫卵囊黑化相关，推测可能是斯氏按蚊的前酚氧化酶的活化酶。

The plasmid pcDNA3.1-3-1E and pcDNA3.1 was respectively used to immunize SPF chicks by injection intra-muscularly in thigh muscle at 14 and 21 days of age.Chicks in each group except that in the unchallenged control group were challenged with 5×104 E.acervulina sporulated oocysts at 28 days post-inoculation,and the immune protective efficacy was observed.

将构建的重组质粒以及空载体质粒分别于14、21日龄分2次经腿部肌肉注射免疫SPF雏鸡，28日龄除非免疫非感染对照组外各组攻击性感染5×104个堆形艾美球虫孢子化卵囊，观察真核表达质粒对球虫感染鸡的免疫保护作用并探讨其免疫保护机理。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
