A total of 151 fecal specimens from chickens were randomly collected from local markets in Uberlândia and Belo Horizonte in the state of Minas Gerais, Brazil, to evaluate the presence of Enterocytozoon bieneusi by polymerase chain reaction (PCR). Enterocytozoon bieneusi was identified in 24 fecal samples (15.9%). This represents the first report of E. bieneusi in chickens in Brazil. All PCR-positive specimens were sequenced and 4 genotypes were identified, Peru 6, Peru 11, Type IV, and D. All four genotypes have previously been reported as human pathogens and are potentially zoonotic. Our results demonstrate that human-pathogenic E. bieneusi genotypes are present in chickens in Brazil, corroborating their potential role as a source of human infection and environmental contamination.
从巴西米纳斯吉拉斯州乌贝兰迪亚和贝洛奥里藏特的当地市场随机采集了151份鸡的粪便样本，通过聚合酶链反应（PCR）评估微小隐孢子虫的存在情况。在24份粪便样本（15.9%）中鉴定出微小隐孢子虫。这是巴西鸡群中首次报告微小隐孢子虫。对所有PCR阳性样本进行测序，鉴定出4种基因型，即秘鲁6型、秘鲁11型、IV型和D型。此前已报道这四种基因型均为人类病原体，具有潜在的人畜共患病性。我们的结果表明，巴西鸡群中存在人类致病性微小隐孢子虫基因型，证实了它们作为人类感染源和环境污染源的潜在作用。
