小孢子虫的

After using both of the two immunosupprssion methods, we can establish the animal model successfully when inoculated by CSO, and the efficacity of the second method is better than the first one.2 In order to further understood the endogenous development of Cryptosporidium human strain in mice.

作者采用19日龄昆明系小白鼠作为模型动物，随机分成8组，分3个感染剂量进行人源隐孢子虫分离株感染系列筛选试验，并确定随剂量和时间不同对人源隐孢子虫在小白鼠寄生部位的影响。

KM strain mice immunosuppressed with 7. 5～10mg/L DEX in drinking water had the higher oocysts output and fewer dead than other groups.(4) There was no significant difference infection rate between groups inoculated with different number CSO and groups inoculated CSO with conserved different time. Trial were divided into control, groups of 50mg/kg /d, 100 mg/kg /d and 200 mg/kg /d dose of the drug to study the anticryptosporidial activities of nitazoxanide in an immunosuppressed mice model. The experimental results showed the treatment with 200mg/kg bw /day was significant inhibition of oocyst excretion. To detect the two cryptosporidiums strain C.

实验结果表明：C.parvum虫种能够感染上本实验所采用的BALB／c和昆明小白鼠两种小鼠，而C.andersoni没有能够感染本次实验小鼠；且从小鼠感染后的排卵囊量和小鼠的生存状态来看，采用5～6周龄的KM鼠能获得最大量的隐孢子虫卵囊，小鼠的死亡数最少；每升饮水中地塞米松量为7.5mg～10mg组比12.5mg以上组小鼠死亡数量少，比5mg／L以下组排卵囊数量多；接种不同卵囊数和卵囊的保存时间这两个参数均对小鼠受感染后的排卵囊情况影响不大。

In order to better understand their phylogenetic relationship and identify the uncertain species, the sequences of the small subunit ribosomal RNA (ssurRNA, 16 S rRNA) genes of nine microsporidia infectious to the silkworm, Bombyx mori, were determined.

微孢子虫是真核生物，但其核糖体及核糖体RNA为原核生物型。为探讨9种家蚕病原性微孢子虫的种属地位及亲缘关系，对已广泛用於生物进化分类的核糖体小亚单位RNA基因进行了研究。

Miescher (1843) in Switzerland from the Rattus rat skeletal muscle was found after Sarcocystis, when he called Milosevic tubule (Miescher 's tabules), a growing number of Sarcocystis in other tissues of the animals was found and naming.

Miescher(1843)在瑞士从家鼠骨骼肌中发现鼠住肉孢子虫后，当时他称其为米氏小管（Miescher 's tabules），越来越多的肉孢子虫在其他的动物组织中被发现并定名。

The small round blue organisms at the lumenal border are cryptosporidia.

在内腔边界的小圆兰色的生物体是隐孢子虫。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
