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.

Main Results:

  • Molecular technologies show promise for accelerated TB diagnosis.
  • These advancements can lead to more definitive epidemiologic linkages between TB cases.
  • A range of methods, from traditional to molecular, are available for rapid TB detection.

Conclusions:

  • Emerging molecular technologies are revolutionizing tuberculosis diagnostics.
  • Faster diagnosis and improved case tracking are key benefits.
  • A comprehensive understanding of various diagnostic methods is essential for combating TB.
