Bioinformatics in Metagenomics


Introduction to Metagenomics

Metagenomics research takes the entire microbial community in a specific habitat as the research object. It does not need to be separated and cultivated. It directly extracts environmental sample DNA for sequencing, and studies the community structure, species classification, system evolution, gene function and metabolic network of environmental microbes. It is widely used in the field of microorganisms. The biggest difference between metagenomics research and traditional microbial research methods is that the microorganisms are regarded as a whole, and the steps of cultivating and separating individual microorganisms are eliminated, and all microorganisms in the environment can be directly studied, and then all microorganisms can be analyzed comprehensively. For example, for patients with long-term, recurrent diarrhea, the possible cause may be inflammation of the digestive tract or specific viral or microbial infections caused by the disorder of the intestinal ecosystem. Through the metagenomic sequencing analysis of the patient's stool, the OUT classification analysis can determine whether there is an intestinal ecosystem disorder, and the genome assembly and comparison can determine whether there is a specific pathogen. Metagenomics analysis has been widely used in various fields of biomedical research.

Significance of Metagenomics Data Analysis

  1. Directly perform data analysis on the genome of all microbial populations in a specific environment (such as intestinal microbes, skin microbes, etc.).
  2. Environmental microorganisms usually coexist and interact in communities. Metagenomic research can reflect the true living conditions of microorganisms better than individual studies.
  3. In addition to analyzing the diversity and abundance of microbial populations, it can also analyze microbial gene functions and metabolic pathways involved, and discover new genes with specific functions.

Application of Metagenomic Data in Biomedical Research

Microbial metagenomics data analysis has been widely used in all aspects of microbial research with its significant advantages, such as basic disease research and infectious disease research. Metagenomics research has changed the life of the appointed microbes, providing new solutions to many problems involving microbes:

  • Pathogen discovery: Using bioinformatics methods to analyze human saliva, respiratory tract, blood, excreta, skin and other metagenomics data, it can discover unknown and potential pathogenic microorganisms.
  • Pathogenic microbiome research: Metagenomics analysis of the microbiome in disease and health conditions can study the mechanism of microbial infection on the human body.
  • Public health: Identify pathogens from clinical samples to guide the management and treatment strategies of infected patients, public health microbiology, and monitor the source of infectious disease outbreaks in the community.
