New molecular technologies offer faster tuberculosis (TB) diagnosis and improved case tracking. This review covers TB pathogenesis and rapid detection methods, including smears, cultures, and DNA-based techniques.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Molecular Biology

Background:

  • Tuberculosis (TB) remains a significant global health challenge.
  • Accurate and rapid diagnostic methods are crucial for effective disease control and epidemiology.
  • Traditional diagnostic techniques have limitations in speed and specificity.

Purpose of the Study:

  • To review the pathogenesis of tuberculosis.
  • To explore emerging molecular biologic technologies for TB diagnosis.
  • To discuss various rapid detection methods for TB.

Main Methods:

  • Review of existing literature on tuberculosis pathogenesis.
  • Analysis of established diagnostic techniques: acid-fast smear, conventional culture, BACTEC system.
  • Evaluation of newer immunodiagnostic and DNA-based molecular techniques.
