Research is being conducted on the genomic characterization and epidemiology of Mycobacterium tuberculosis, with studies focusing on various lineages and regions, including Kazakhstan, China, and others. The studies appear to be exploring the genetic diversity, evolution, and drug resistance of the bacteria, as well as its transmission and phylogeography in different parts of the world. The scope of the research seems to be global, with multiple countries and regions being investigated to better understand the epidemiology of Mycobacterium tuberculosis.
