概括
在南极长期停留会改变肠道微生物群的组成,这取决于个人最初的肠道微生物群. 这些变化凸显了人类肠道微生物群适应极端,孤立的环境.
科学领域:
- 微生物组研究 微生物组研究
- 人类的适应能力
- 环境健康 环境健康
背景情况:
- 南极研究站面临极端的环境挑战,通过肠道微生物群影响宿主健康.
- 关于肠道微生物群适应长期南极任务的研究有限,因为样本大小小和持续时间短.
研究的目的:
- 研究长期南极居住对人类肠道微生物群的纵向影响.
- 了解先前存在的肠道微生物群类型如何影响适应极端,孤立的环境.
主要方法:
- 在长达16个月的时间内,分析了48名参与者的467个便样本.
- 在南极站停留之前,期间和之后进行纵向采样.
主要成果:
- 确定了三种不同的肠道微生物群类型,显示了南极停留期间和之后的差异性变化.
- 普雷沃特拉主导的微生物群对环境变化 (例如饮食) 更容易受到影响,而不是巴克特罗伊德主导的微生物群.
- 虽然占主导地位的属性保持稳定,但较小的属性则调节了变化;同居影响了参与者之间的微生物群组成.
结论:
- 在南极长期居住会显著改变肠道微生物群的组成,其影响取决于个体的基线微生物群.
- 研究结果提供了对人类肠道微生物群在极端和孤立条件下的适应机制的见解.

Anatomy of the Intestines
71.6K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Bacterial Flora of the Large Intestine

The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.
