概括

工业化改变了中国人口的肠道微生物组和抵抗组. 与西部地区相比,东部地区的多样性下降,抗生素耐药性基因 (ARG) 较少.

科学领域:

微生物组研究的研究.
公共卫生公共卫生
基因组学就是基因组学.

背景情况:

工业化推动了生活方式的改变,影响了肠道健康.
了解肠道微生物组和抗体变化对于中国的公共卫生管理至关重要.
中国各地的工业化不均,需要针对特定地区的卫生战略.

研究的目的:

研究受中国东部和西部工业化影响的肠道微生物组和抗体组的动态变化.
为了比较肠道微生物的组成,多样性和抗生素耐药性基因特征,在工业发达的中国东部和发展中中国西部之间.
识别潜在的健康风险,并根据区域差异为公共卫生政策提供信息.

主要方法:

对来自中国1382名健康个体的肠道微生物群的基因组学分析.
微生物物种组成,功能途径和抗生素耐药性基因 (ARG) 在东方和西方人群之间的比较.
重建元基因组组装基因组以分析大肠杆菌中的毒性因子基因 (VFGs) 和移动遗传元素 (MGE).

主要成果:

东部种群在微生物组成和途径上表现出更大的个体间差异,但个体内多样性下降.
在东部人口的肠道微生物群中观察到ARG的丰度和丰度明显较低.
西方人群中的大肠杆菌携带的毒性因子基因 (VFG) 和移动遗传元素 (MGE) 比东方人群的更多.

结论:

工业化导致了中国东部和西部人口之间肠道微生物组和抗体组的明显变化.
这些发现对中国的公共卫生有着至关重要的意义.
对于管理病原性感染和公共卫生,可能需要特定区域的战略.

Anatomy of the Intestines

Anatomy of the Intestines

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...

Factors Affecting the Risk of Infection

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
