摘要: 用蒸馏水代替PBS稀释Sheather’s蔗糖溶液,并测定不同稀释度的蔗糖溶液密度,使用不同密度的蔗糖溶液分离纯化安氏隐孢子虫、贝氏隐孢子虫和猪隐孢子虫卵囊,计算纯化后的卵囊回收率和卵囊活性。安氏隐孢子虫、贝氏隐孢子虫和猪隐孢子虫卵囊纯化后的总回收率分别为47.5%、49.6%和41.7%;孔雀绿染色活性检测的活性率分别为97.9%、96.7%和95.1%;37 ℃水浴1 h后的脱囊率分别为87.9%、80.0%和81.7%。

Abstract: Sheather’s sucrose solution diluted with distilled water as an alternative to PBS was used to purify oocysts of three different Cryptosporidium spp. The recovery rate of purified Cryptosporidium andersoni, C. baileyi and C. suis oocysts was 47.5%, 49.6% and 41.7%, respectively. The viability of the oocysts was 97.9%, 96.7%, and 95.1%, respectively. After 1 h incubation in a 37 ℃ water bath, the excystation rate of the oocysts was 87.9%, 80.0%, and 81.7%, respectively.
