Abstract：
OBJECTIVE: Balantidium coli, is a protozoa that can infect humans. Balantidium coli infection is mostly asymptomatic, but can cause of diarrhea, abdominal pain and sometimes perforated colon. There are only few previous reports regarding the infant balantidiasis and there is a little information about its clinical signs and treatment. In Islamic countries pig farming and consumption is prohibited and reservoir host is unknown.
METHODS: 1.5 years old boy showed sever anorexia and diarrhea. The affected infant was depressed. The evaluation of fecal examination revealed a large number of B. coli trophozoites and cysts leaded us to an uncommon presentation of B. coli in the infant.
RESULTS: A few reports of human balantidiasis from Iran seems quite extraordinary. Wild boars have been proposed the responsible for transmission of human infection in Iran.
CONCLUSIONS: However, this report as the first report of infant balantidiasis in Iran supports the role of other sources and domestic or wild animals as reservoir hosts for B. coli in Iran.

摘要：
目标：大肠杆菌，是一种能感染人类的原生动物.大肠埃希菌感染大多无症状,但可能导致腹泻，腹痛，有时结肠穿孔。以前关于婴儿鲍尔迪病的报道很少，关于其临床体征和治疗的信息很少。在伊斯兰国家，禁止养猪和消费，水库宿主未知。
方法：1.5岁男童表现为严重厌食和腹泻。受影响的婴儿感到沮丧。粪便检查的评估显示，大量的大肠杆菌滋养体和囊肿使我们在婴儿中罕见地出现了大肠杆菌。
结果：来自伊朗的一些关于人类鲍尔迪病的报道似乎非常不寻常。有人提议野猪负责在伊朗传播人类感染。
结论：然而，该报告作为伊朗婴儿鲍兰迪病的第一份报告，支持其他来源以及家畜或野生动物作为伊朗大肠杆菌的水库宿主的作用。
