Coprologic examination of nine Siberian chipmunks (Eutamias sibiricus) imported from Southeast Asia revealed infection with Cryptosporidium sp. Experimental inoculation of BALB/c mice proved their susceptibility to the infection. Infected mice shed oocysts 14-35 days postinfection. Oocyst morphology was similar to that reported for C. muris in previous studies, oocysts were 8.1 (7.0-9.0) x 5.9 (5.0-6.5) microns. Clinical signs were absent in naturally infected chipmunks and experimental mice. Histologic examinations of mice revealed numerous developmental stages of C. muris in the glandular stomach. Analysis of partial small subunit rRNA gene sequences confirmed identity of these isolates as C. muris. Our results represent the first report of C. muris in members of the family Sciuridae.
对9只从东南亚进口的西伯利亚花栗鼠（Eutamias sibiricus）进行粪便学检查，发现感染了隐孢子虫属（Cryptosporidium sp.）。对BALB/c小鼠进行实验接种证明它们对该感染易感。感染小鼠在感染后14 - 35天排出卵囊。卵囊形态与先前研究中报道的鼠隐孢子虫（C. muris）相似，卵囊大小为8.1（7.0 - 9.0）×5.9（5.0 - 6.5）微米。自然感染的花栗鼠和实验小鼠均无临床症状。对小鼠进行组织学检查发现腺胃中有大量鼠隐孢子虫的发育阶段。对部分小亚基rRNA基因序列的分析证实这些分离株为鼠隐孢子虫。我们的结果代表了松鼠科（Sciuridae）成员中鼠隐孢子虫的首次报道。
