研究表明，只有 2%的猫会排出一次胞囊，并且以后不再排出，即使猫体内仍有寄生虫。

Results One 446 bp PCR product was observed by agarose gel electrophoresis for all three kinds of templates. The PCR sensitivity by Chelex-100 extracted DNA reached for detection of a specimen containing only 1/2 oocyst.

结果3种方法制备的微小隐孢子虫卵囊模板用于PCR检测均获得1条446 bp条带，Chelex-100提取的DNA用于PCR检测的敏感性至少达0.5个卵囊。

The highest oocysts producing period occurred in April, and the highest oocyst hatching and density of population was in May. And the sexual reproduction process had relation to temperature, food and size of planarians.

卵囊产出的高峰在4月，卵囊孵化与种群密度最高峰在5月，其有性生殖过程与温度、食物、虫体大小密切相关。

Objective To explore the ageand gender of mice, the optimal dose of the dexamethasone phosphate and the optimal time of immunosuppression in the mice model applied for C.parvum oocyst infectivity and reproduce.

目的 探索适合隐孢子虫卵囊传代和扩增模型小鼠的性别、日龄、免疫抑制时间和免疫抑制剂地塞米松磷酸钠的最佳剂量。

Results All six strains amplified by the primers FF showed same detection rate with 021. Sensitivity test indicated that DNA of 1 oocyst per gram of feces could be detected by the PCR.

结果 引物FF扩增 6株C 。parvum均能产生预计 6 0 3bp的片段，引物FF和引物 0 2 1粪样检测结果完全一致，其敏感性是可检出 1个卵囊的DNA。

Results 4.16×10 9 oocysts were obtained in 30 mice in the 3rd group with dexamethasone of 20 μg/ml in drinking water. No significant difference in the oocyst recovery, purity and infectivity was found between methods using saturated saline floatation and sucrose density gradient centrifugation. The infectivity of the oocysts obtained from the same origin but different animals was similar.

结果 地塞米松加入量为 2 0 μg/ml的第 3组获得的卵囊量高达 4 。16× 10 9/ 30个小鼠；用饱和盐水漂浮法与用蔗糖密度梯度离心法纯化得到的卵囊具有相同的回收率和纯度；从感染小鼠与犊牛中获得的卵囊在感染性上差异不显著。
