Blastocystis is a common intestinal protist in humans and animals. Currently, Blastocystis infection in bar-headed geese is unknown. To understand the prevalence and distribution of Blastocystis subtypes in bar-headed geese, fecal samples were collected from 358 bar-headed geese in three regions. The total infection rate of Blastocystis in bar-headed in China was 5.9% (21/358), with 5.0% (6/120) in Aba (Ngawa) Tibetan and Qiang Autonomous Prefect, Sichuan province, 11.8% (14/119) in Maqu county, Gansu province, and 0.8% (1/119) in Caohai, Wei ning county, Guizhou province. The differences in prevalence rates by region were statistically significant. Sequences analyses showed that one known subtype (ST7, n = 16) and one potentially novel ST (n = 5) in bar-headed geese were detected in this study. This is the first report on the prevalence and subtype distribution of Blastocystis in bar-headed geese, which will improve our understanding of the epidemiology and public health implications of Blastocystis infection in wild migratory birds.
肠内原虫 Blastocystis 在人类和动物中很常见。目前，关于斑头雁中的 Blastocystis 感染尚不清楚。为了了解斑头雁中 Blastocystis 亚型的流行和分布情况，从中国三个地区的 358 只斑头雁中采集了粪便样本。在中国，斑头雁 Blastocystis 的总感染率为 5.9%（21/358），四川阿坝（若尔盖）藏族羌族自治州为 5.0%（6/120），甘肃玛曲县为 11.8%（14/119），贵州威宁草海为 0.8%（1/119）。不同地区的感染率存在统计学差异。序列分析表明，本研究在斑头雁中检测到了一种已知亚型（ST7，n=16）和一种潜在新型 ST（n=5）。这是首次报道斑头雁中 Blastocystis 的流行和亚型分布情况，将有助于我们了解 Blastocystis 感染在野生候鸟中的流行病学和公共卫生意义。
