Modern Molecular Taxonomy01:29

Modern Molecular Taxonomy

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...
Evolution of Microbial Genome01:08

Evolution of Microbial Genome

Microbial genome evolution is a highly dynamic process shaped by continual gene gain and loss across species and strains. This genomic flexibility allows microorganisms to adapt rapidly to environmental pressures and interactions with other organisms. Central to understanding this diversity is the distinction between the core and pan genomes.The core genome comprises the genes shared by all sampled strains of a species, representing essential functions needed for fundamental cellular processes.
Microbial Phylogeny01:28

Microbial Phylogeny

Understanding the evolutionary relationships among microorganisms is fundamental to microbial ecology and taxonomy. Phylogenetic trees are essential tools for inferring these relationships, relying primarily on comparative analyses of molecular sequences such as DNA, RNA, or proteins. In microbial studies, these trees typically depict the evolutionary paths of diverse bacterial and archaeal species by mapping genetic differences accumulated over time.Phylogenetic trees are composed of tips,...
Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...
Tuberculosis01:23

Tuberculosis

Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...
Gene Duplication and Divergence02:37

Gene Duplication and Divergence

The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was  generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are characterized.

Area of Science:

  • Genomics
  • Bioinformatics
  • Microbiology

Background:

  • Genomic variations drive phenotypic differences in closely related organisms.
  • Mechanisms like replication error, recombination, and transposition generate SNPs, indels, and structural variations.
  • A comprehensive database for Mycobacterium tuberculosis complex genomic variations is lacking.

Purpose of the Study:

  • To develop a user-friendly, web-based database for exploring genomic variations within the Mycobacterium tuberculosis complex.
  • To facilitate the understanding of genotype-phenotype relationships and support clinical applications.

Main Methods:

  • The Mycobacterium Genome Diversity Database (MGDD) was created as a free, web-based resource.
  • Pairwise genome comparisons using a described tool generate variation data.
  • Users can search for specific variations (SNPs, indels, tandem repeats, divergent regions) within genes or genomic locations.

Main Results:

  • MGDD provides a searchable repository of genomic differences among M. tuberculosis complex strains and species.
  • The database enables identification of SNPs, indels, tandem repeats, and divergent regions.
  • Search functionality allows targeted queries based on genes or genomic locations.

Conclusions:

  • The MGDD database effectively identifies genomic differences between M. tuberculosis complex strains/species.
  • Its user-friendly interface supports users without computational expertise.
  • MGDD is a valuable tool for clinicians and researchers studying tuberculosis and other Mycobacterial diseases.
