has been reported from both laboratory and wild rodents in worldwide. During routine care, soft consistency was observed in feces of Swiss albino mice. Motile spp. trophozoites were observed microscopically on all fecal preparations after stained with Lugol's iodine solution. The trophozoites were broadly ovoid in a form with a pointed end. They possess two large nuclei and an adhesive disk whose length overlapped one-half of the trophozoite body length. The caudal flagella are unequal. β giardin () gene region of isolates was successfully amplified and sequenced. According to sequence analyses of the gene region, the mice isolate was identified as s and deposited in GenBank (Accession Number: MK675656). The sequence of was shown 99.3-99.7% identity with the isolates of reported from different countries in GenBank. We have firstly demonstrated trophozoites in the fecal samples of naturally infected Swiss albino mice in Turkey.
在全球范围内，实验室和野生啮齿动物中均有相关报道。在日常护理过程中，观察到瑞士白化小鼠的粪便质地柔软。用卢戈氏碘液染色后，在所有粪便样本中显微镜下均观察到活动的滋养体。滋养体呈宽卵形，一端尖锐。它们有两个大核和一个黏附盘，黏附盘的长度超过滋养体体长的一半。尾鞭不等长。成功扩增并测序了分离株的β贾第虫（）基因区域。根据该基因区域的序列分析，小鼠分离株被鉴定为，并保藏于GenBank（登录号：MK675656）。该分离株的序列与GenBank中报道的来自不同国家的分离株的序列一致性为99.3 - 99.7%。我们首次在土耳其自然感染的瑞士白化小鼠粪便样本中证实了滋养体的存在。
