Balantiosis, a rare zoonotic infection resulting in dysentery, is caused by the large ciliated protozoan parasite . Humans acquire this organism via the faecal-oral route. Very rarely, extraintestinal infections can occur in the urinary tract system. There are very few case reports of urinary balantiosis in humans.
Here, an interesting case of urinary balantiosis in a 35-year-old addicted woman with multiple health problems including spontaneous abortion and diabetes is reported. Her midstream urine sample, collected while all sterile precautions were being taken, demonstrated . along with and bacteria. was identified by its characteristic morphology and rapid rotary motility in the urinary tract, which is an abnormal site for invasion by this parasite.
To the best of our knowledge, this is only the eighth case described in literature in which was detected in urine sediment; it is reported for its rarity and for future reference.
结肠小袋纤毛虫病是一种由大型纤毛虫寄生虫引起的罕见人畜共患感染，可导致痢疾。人类通过粪-口途径感染这种病原体。极罕见情况下，可在泌尿系统发生肠外感染。人类泌尿生殖道结肠小袋纤毛虫病的病例报告非常少。
本文报告了一例35岁成瘾女性患泌尿生殖道结肠小袋纤毛虫病的有趣病例，该女性有包括自然流产和糖尿病在内的多种健康问题。在采取所有无菌预防措施的情况下采集的她的中段尿样本显示有结肠小袋纤毛虫以及酵母菌和细菌。结肠小袋纤毛虫通过其特征性形态和在泌尿道中的快速旋转运动得以识别，泌尿道是该寄生虫入侵的异常部位。
据我们所知，这是文献中描述的第八例在尿沉渣中检测到结肠小袋纤毛虫的病例；因其罕见性及供未来参考而予以报告。
