在原生动物微小隐孢子虫的培养中,已经使用了各种技术来感染细胞单层。然而,这些方法大多依赖于使用胰酶和/或胆盐在体外剥离子孢子,然后在将子孢子添加到亚融合单层之前,在没有激发液的情况下洗涤它们。这种方法不仅增加了在体外建立感染所需的时间,而且还导致自由子孢子长时间暴露在环境条件下。在这里,我们报告了一种简单、快速、有效的方法来获得持续感染的FC。微小细胞单层。这项技术依赖于寄生虫在37℃而不是在室温下用次氯酸钠预处理后的激发能力。通过将表面灭菌的卵囊直接添加到单层,子孢子在分泌时可以立即进入宿主细胞。
A variety of techniques have been used to infect cell monolayers in culture with the protozoan,Cryptosporidium parvum. However, most of these methods rely on the use of trypsin and/or bile salts to excyst sporozoites in vitro, followed by washing sporozoites free of excystation solution prior to their addition to subconfluent monolayers. This method not only increases the amount of time required to establish infections in vitro, but also results in prolonged exposure of free sporozoites to environmental conditions. Here we report a simple, fast, and efficient method of obtaining consistent infections ofC. parvumin cell monolayers. This technique relies on the ability of the parasite to excyst at 37°C but not at room temperature following pretreatment with sodium hypochlorite. By adding surface-sterilized oocysts directly to monolayers, sporozoites have access to host cells immediately upon excystation.
