Intestinal Microecology

Intestinal microbes

After human beings are born, due to the exposure of the surrounding environment and diet, a stable microecology of intestinal flora is gradually established. Therefore, there is a complex microecosystem composed of about 1x1014 microbes in the human intestine, the number of which is more than 10 times that of the body's cells, including more than 1,000 kinds of anaerobic bacteria and aerobic bacteria.

The intestinal microecosystem is the largest and most important microecosystem in the human body. These intestinal microbes and their metabolites play an extremely significant role in the metabolism of nutrients, the body's development, immunity and diseases. Many studies have shown that intestinal microbes are directly related to the pathogenesis of many diseases, such as cancer, obesity, and neurodegenerative diseases.

Research Direction

The main research directions of intestinal microbes including,

  • Look for the difference in intestinal flora between the disease group and the healthy group.
  • Study the intestinal flora of the drug or diet intervention group.
  • Intestinal flora of the same population but at different growth and development stages.
  • Study the intestinal flora of a population in the development process of a certain disease.
  • Study the microbes in multiple body parts of the same population.

Technical Process

  • The process of intestinal microbe high-throughput sequencing analysis.

  • The process of intestinal microbe PCR-DEEG analysis. DEGG (Denatured gradient gel electrophoresis) has become one of the main molecular biology methods to study the structure of the microbial community.

Sample Type and Detection Type

  • The sample types are feces or intestinal contents of humans, mice, monkeys, sheep, fish, and other animals. Recommend to use our product - microbial sample collection.
  • The requirements of DNA sample: total DNA ≥ 200ng, DNA concentration ≥ 10ng/μL, OD260/280 = 1.8 - 2.0, ensure that DNA is not degraded, and repeated freezing-thawing should be avoided during sample preservation.
  • The detection types are bacteria, fungi, actinomycetes, etc.
