Summary
Rapid molecular and phenotypic methods offer promising new tools for diagnosing drug-resistant tuberculosis (TB). Further evaluation is needed for widespread implementation in high-burden countries.
Area of Science:
- Microbiology
- Infectious Diseases
- Molecular Biology
Background:
- Tuberculosis (TB) remains a leading global cause of infectious death.
- Emergence of multidrug-resistant TB strains poses a significant threat to global health.
- Urgent need for improved diagnostics and treatments to control TB spread.
Purpose of the Study:
- To review recent advancements in rapid diagnosis and drug resistance detection for tuberculosis.
- To highlight new molecular and non-molecular diagnostic approaches.
Main Methods:
- Evaluation of nucleic acid amplification techniques (commercial and in-house).
- Assessment of non-molecular diagnostic methods.
- Testing of genotypic and phenotypic methods on M. tuberculosis strains and clinical samples.
Main Results:
- Advances in molecular biology have yielded new tools for rapid TB diagnosis.
- Promising accuracy observed in novel diagnostic tests.
- Some new methods are suitable for clinical mycobacteriology laboratories.
Conclusions:
- New genotypic and phenotypic methods for rapid TB diagnosis and drug resistance detection have been developed.
- Controlled evaluations in high-endemic countries are essential for routine implementation.
- These advancements are crucial for enhancing global TB control strategies.
