- 为了比较红色甜菜作为猪饮食中氧化的替代品.
- 确定红色甜菜的最佳水平,以促进断奶猪的肠道健康.
主要方法:
- 断奶猪 (28天) 接受了对照,氧化,2%红甜菜 (RB2) 或4%红甜菜 (RB4) 饮食14天.
- 在安乐死后采集了血液和消化器样本,用于微生物和代谢物分析.
- 分析了微生物组成和短链脂肪酸 (SCFA) 和胆酸度.
主要成果:
- 2%的红甜菜饮食 (RB2) 与其他饮食相比,增强了肠道微生物的丰富性.
- 更高的红红含量 (4% - RB4) 降低了脑内微生物的多样性,降低了SCFA和二次胆酸度.
- 在RB4群体中观察到蛋白质细菌的丰富性增加,可能与产生乳酸的细菌有关.

Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Microbiota of the Stomach and Small Intestine
The human gastrointestinal (GI) tract is characterized by distinct physicochemical conditions that shape its microbial communities. Among these, the stomach presents a particularly challenging environment for microbial colonization due to its highly acidic pH, ranging from 1 to 3. This extreme acidity effectively limits microbial density. However, certain acid-tolerant microorganisms are capable of surviving in this niche. Notably, Helicobacter pylori can colonize the gastric mucosa,...
Dysbiosis of the Gut Microbiota
The human gut microbiome includes a diverse array of microbial species, including beneficial commensals and opportunistic pathogens, which interact to support host health. These microbes contribute to essential functions such as nutrient metabolism, immune system modulation, and maintenance of intestinal barrier integrity. However, disruptions to this equilibrium—referred to as dysbiosis—can have widespread physiological consequences.Dysbiosis is often characterized by reduced microbial...
Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
