RESUMEN
With the emergence and globally spread of drug-resistant bacteria, the discovery and development of new antibacterial drugs is imminent. The symbiotic bacteria distributed in different parts of the body can produce a variety of antibacterial molecules to inhibit the colonization and infection of pathogenic bacteria. Human symbiotic bacteria provide a potential treasure house of resource for the research and development of new drugs with broad new molecular structures and action mechanism. With the further development of bioinformatics tools, synthetic biology and omics technology such as genomics, the mining of human symbiotic bacteria antibacterial molecules will be more in-depth and provide an effective way to solve the problem of drug resistance. Here, we review the antimicrobial molecules produced by human symbiotic bacteria and introduce several methods to explore the resources of natural antibacterial drugs. With the development of modern biotechnology, the antimicrobial molecules of human symbiotic bacteria will be more comprehensively and systematically explored and applied.
