Abstract
The emergence of resistance to various antibiotics has become a major threat for combating infectious diseases resulting in persistent infection and increased mortality. Whole genome sequencing is a promising tool for finding mutations causing resistance and to distinguish the resistant strains. ,Mycobacterium tuberculosis a global threat and the recent breakout in Multi-drug resistance strain (MDR-TB) and Extensively Drug resistance (XDR-TB) has challenged researchers in the diagnosis and to provide effective treatment. The study focuses on the analysis of whole genome high-throughput data of Mycobacterium tuberculosis over a time period of 1999-2017 including drug-resistant strain, multi-drug resistant strain and the extensively drug-resistant strain from different geographical locations collected from NCBI-SRA. An effective pipeline is developed to analyze and interpret mutations causing antibiotic resistance using bioinformatics and NGS approach. The analysis provides discovery of genetic changes, drug-resistant genes, mutated amino acid and its position in the chromosome. We have characterized 10 DR-TB, 30 MDR-TB, 10 XDR-TB, 5 Pre-XDR-TB and 15 XXDR-TB based on the mutation pattern of resistance. Results provide a determination of anti-tuberculosis drug resistance and identification of resistance strain based on the identified SNP biomarkers.Biography
