赛加羚羊是迁徙的羚羊，栖息在欧亚大陆的草原上。在过去的世纪里，塞加羚羊已经被大规模死亡事件和激烈的偷猎推向灭绝的边缘。然而，尽管赛加羚羊作为一种受保护的动物受到高度关注，但人们对其生物学知之甚少。特别是，尽管Saiga的肠道微生物群在健康方面具有潜在的重要性，但尚未对其进行研究。在这里，我们从哈萨克斯坦的两个地理上不同的种群中分离出赛加羚羊的肠道微生物群，并将其与其他羚羊物种进行比较。我们确定了一个一致的肠道微生物多样性和组成之间的个人和两个赛加种群在一年内没有死亡，超过85%的细菌属是共同的两个种群，尽管巨大的地理分离。我们进一步表明，赛加羚羊的肠道菌群与其他五种羚羊的肠道菌群相似。在赛加羚羊微生物群中未检测到赛加羚羊大规模死亡的假定病原体多杀性巴氏杆菌。我们的研究结果首次描述了赛加羚羊肠道微生物群，为未来研究微生物群在健康和大规模死亡中的作用提供了基线，并支持保护这一极度濒危物种。
The Saiga are migratory antelopes inhabiting the grasslands of Eurasia. Over the last century, Saiga have been pushed to the brink of extinction by mass mortality events and intense poaching. Yet, despite the high profile of the Saiga as an animal of conservation concern, little is known of its biology. In particular, the gut microbiota of Saiga has not been studied, despite its potential importance in health. Here, we characterise the gut microbiota of Saiga from two geographically distinct populations in Kazakhstan and compare it with that of other antelope species. We identified a consistent gut microbial diversity and composition among individuals and across two Saiga populations during a year without die-offs, with over 85% of bacterial genera being common to both populations despite vast geographic separation. We further show that the Saiga gut microbiota resembled that of five other antelopes. The putative causative agent of Saiga mass die-offs, Pasteurella multocida, was not detected in the Saiga microbiota. Our findings provide the first description of the Saiga gut microbiota, generating a baseline for future work investigating the microbiota’s role in health and mass die-offs, and supporting the conservation of this critically endangered species.
