Oocysts of Cryptosporidium muris (Apicomplexa: Cryptosporidiidae) were obtained from the feces of naturally infected calves. Oocysts were fully sporulated in fresh feces, measured 7.4 X 5.6 (6.6 - 7.9 X 5.3 - 6.5) micron, and possessed a longitudinal suture along one pole of the oocyst wall. Morphologic and biologic evidence obtained from this study demonstrated that C. muris is a species distinct from Cryptosporidium parvum, which has smaller oocysts.
微小隐孢子虫（顶复门：隐孢子虫科）的卵囊取自自然感染小牛的粪便。卵囊在新鲜粪便中完全孢子化，大小为7.4×5.6（6.6 - 7.9×5.3 - 6.5）微米，并且在卵囊壁的一极有一条纵向缝线。本研究获得的形态学和生物学证据表明，微小隐孢子虫是一个与微小隐孢子虫不同的物种，后者的卵囊较小。
