species are ubiquitous enteric protozoan pathogens of vertebrates distributed worldwide. The purpose of this study was to gain insight into the zoonotic potential and genetic diversity of spp. in Bactrian camels in Xinjiang, northwestern China. A total of 476 fecal samples were collected from 16 collection sites in Xinjiang and screened for by PCR. The prevalence of was 7.6% (36/476). Six species, ( = 24), ( = 6), ( = 2), ( = 2), ( = 1), and ( = 1), were identified based on sequence analysis of the small subunit (SSU) rRNA gene. Sequence analysis of the gene identified six isolates as subtypes, such as If-like-A15G2 ( = 5) and IIdA15G1 ( = 1), two isolates, such as subtype XIIa ( = 2), and one isolate, such as Ixias IkA19G1 ( = 1). This is the first report of , , , and in Bactrian camels in China. These results indicated that the Bactrian camel may be an important reservoir for zoonotic spp. and these infections may be a public health threat in this region.
[具体物种名称]是广泛分布于世界各地脊椎动物体内的肠道原生动物病原体。本研究旨在深入了解中国西北部新疆双峰驼体内[具体物种名称]的人畜共患病潜力和遗传多样性。从新疆的16个采集点共收集了476份粪便样本，并通过聚合酶链反应（PCR）对[具体物种名称]进行筛查。[具体物种名称]的感染率为7.6%（36/476）。基于小亚基（SSU）核糖体RNA基因的序列分析，鉴定出6种[具体物种名称]，分别为[物种1]（共24株）、[物种2]（共6株）、[物种3]（共2株）、[物种4]（共2株）、[物种5]（共1株）和[物种6]（共1株）。基于[具体基因名称]基因的序列分析，将6株[具体物种名称]分离株鉴定为不同亚型，如If样-A15G2（共5株）和IIdA15G1（共1株），2株[另一物种名称]分离株，如XIIa亚型（共2株），以及1株[又一物种名称]分离株，如Ixias IkA19G1（共1株）。这是中国双峰驼体内[物种1]、[物种2]、[物种3]和[物种4]的首次报道。这些结果表明，双峰驼可能是[具体物种名称]人畜共患病的重要宿主，这些感染可能对该地区的公共卫生构成威胁。
