The respiratory microbiota differs significantly between tuberculosis patients and healthy individuals. Further deep sequencing studies are recommended to understand these microbial variations in the respiratory system.
Area of Science:
- Microbiology
- Pulmonology
- Genomics
Background:
- Previous research indicates distinct respiratory microbiota in tuberculosis (TB) patients compared to healthy individuals.
- Understanding these differences is crucial for potential diagnostic or therapeutic strategies.
Purpose of the Study:
- To quantify and compare the relative proportions of respiratory microbiota at phylum and genus levels between TB cases and healthy controls.
Main Methods:
- A systematic literature search was conducted on PubMed and Google Scholar.
- Statistical analysis was performed using STATA version 11, with pooled estimates visualized in graphs.
Main Results:
- Firmicutes and Proteobacteria were the most abundant phyla in both groups. Streptococcus, Neisseria, Prevotella, and Veillonella were prominent in TB patients.
- Prevotella, Gammaproteobacteria, Streptococcus, and Haemophilus were abundant in healthy controls. Unique genera were identified in each group.
Conclusions:
- Significant differences exist in respiratory microbiota composition between TB patients and healthy controls.
- Further deep sequencing studies are necessary to elucidate microbial variations in the respiratory system related to TB.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
