With the increasing prevalence of abscess diseases,traditional microbiological culture methods have become inadequate for clinical needs due to their long incubation periods and low positive rates.Based on the rapid development of sequencing technology,metagenomics technology has been extensively used in clinical practice,enabling the rapid and accurate identification of microbial community structures and diversity,as well as the detection of various pathogenic bacteria and gene functions.Metagenomics has emerged as a new option for pathogenic diagnosis.In this paper,the application and development of metagenomics technology in the pathogenic diagnosis of abscesses are reviewed.
