New Agar Medium for the Isolation and Testing Susceptibility of Mycobacterium Tuberculosis Against Drugs

Tech ID: 00-05

Summary
Scientists at National Jewish Health have developed a new agar medium for the isolation of M. tuberculosis from patients. The medium can also be used for testing susceptibility of M. tuberculosis against various drugs such as pyrazinamide.

Potential Applications

  • Isolation of M. tuberculosis from patients specimens
  • Sub-cultivation of M. tuberculosis pure cultures
  • Direct and indirect susceptibility testing

Advantages of Invention

  • The medium can be used in regular incubators (without supplemental CO2)
  • The medium can be used at pH 6.0
  • The medium can be used for a test with pyrazinamide
  • The medium is using animal serum (bovine serum for example) instead of OADC
  • The medium is less expensive to produce
  • Pyrazinamide test can be performed more easily and faster

State of Development
The medium has been successfully tested to isolate M. tuberculosis and for susceptibility with pyrazinamide

Further R&D Required
Susceptibility testing against other drugs
