AP19676216 “Evolutionary genomics of Mycobacterium tuberculosis in Kazakhstan: disentangling the threads between ancient and modern outbreaks”

The proposed project aims to improve the control of tuberculosis and study its transmission routes, with a particular focus on the occurrence of MDR-TB outbreaks, using genomic epidemiology techniques, multi-omics analysis, and data mining using a new bioinformatics platform. Genome-wide analysis of local M. tuberculosis isolates will be performed, focusing primarily on the L2 family. Data analysis will identify phylogenetic and drug resistance-associated SNPs, deletion and insertion regions, and CRISPR structure. The bioinformatics platform will allow us to accurately identify clusters and classify subclades of the L2 lineage. In addition, genomic drug susceptibility testing (DST) will be compared with phenotypic DST; and the results of in silico spoligotyping will be confirmed by mass spectrometry.

Novelty

Tuberculosis (TB) caused by the Mycobacterium tuberculosis complex (MTBC) is a public health concern globally. According to the recent WHO report, approximately 6.4 million cases of TB and 1.6 million deaths were registered in 2021 versus 5.8 million cases of TB and 1.5 million deaths in 2020 worldwide. The burden of drug-resistant TB (DR-TB) is also estimated to have increased worldwide between 2020 and 2021 mainly due to COVID-19. The global COVID-19 pandemic has stressed the importance of integrated research for outbreak control including genomics, big data, and modeling. The tuberculosis pandemic, like COVID-19, is made up of many lineages that are evolving at different paces and are superimposed. In this sense, understanding the evolution of outbreaks is important for their control and the use of adequate public health measures. Whole-genome sequencing has been extremely useful in understanding transmission patterns, the development of drug resistance, and bacterial evolution. This research project is aimed to improve TB control and risks by studying tuberculosis transmission with a specific focus on the emergence of MDR-TB outbreaks by using genomic epidemiology and the demographic history of the TB disease in Kazakhstan and Central Asia. In this regard, WGS of local Mtb isolates will be carried out with emphasis on lineage 2.

Aim

We aimed to improve TB control by studying tuberculosis transmission with a specific focus on the emergence of MDR-TB outbreaks by using genomic epidemiology, data mining, and the demographic history of tuberculosis in Kazakhstan and Central Asia.

Expected results

1. Representative sample of Mycobacterium tuberculosis clinical isolates circulating in all regions of the Republic of Kazakhstan will be formed;

2. L2 isolates will be genotyped with real-time PCR using genotype-specific markers to select L2 isolates for whole genome sequencing. Whole genome sequences of the local M. tuberculosis L2 isolates representing all regions of the Republic of Kazakhstan will be produced;

3. A genomic dataset of local M. tuberculosis lineage 2 clinical isolates will be analyzed with computational bioinformatic pipeline;

4. Phylogenetic analysis, cluster definition and classification of the L2 lineage will be carried out with computational genomic pipeline. A pairwise distance matrix will be calculated;

5. In silico predicted spoligotypes of the clinical M. tuberculosis isolates will be validated with masss-spectrometry;

6. A reference set of multi-omics data for M. tuberculosis lineage 2 MDR outbreak clinical isolates and compare transcriptomic and proteomic differences between the hypervirulent and low-virulent strains using RNA-sequencing and label-free quantitative LC-MS/MS approach will be created.
