摘要

Whole-genome sequencing of Mycobacterium tuberculosis (WGS-TB) has revolutionized tuberculosis research by providing high-resolution insights into drug resistance, transmission dynamics, and evolutionary pathways. However, the global research landscape, collaboration networks, and thematic evolution of WGS-TB remain underexplored. A comprehensive dataset of WGS-TB publications was retrieved from Scopus. Analyses were conducted using Bibliometrix for productivity trends, Lotka’s and Bradford’s Laws, normalized word cloud, and thematic mapping; VOSviewer for co-authorship, co-occurrence, bibliographic coupling, and unsupervised term clustering; and CiteSpace for reference co-citation analysis (RCCA) and thematic evolution. Between 1994 and 2025, WGS-TB publications exhibited exponential growth, particularly after 2015. The United States, China, and the United Kingdom were leading contributors, supported by globally connected institutions. Collaboration networks revealed strong North–South partnerships, with South Africa acting as a critical bridge. Keyword and thematic analyses identified dominant themes such as drug resistance, genomics, and epidemiology, with emerging areas including metagenomic sequencing and mutation dynamics. Bradford’s Law identified 12 core journals, while RCCA delineated clusters in drug resistance surveillance and molecular epidemiology. This study offers the first integrative mapping of WGS-TB research, illuminating its thematic evolution, global collaboration structure, and emerging directions in genomic surveillance and precision medicine.
