Widely present in the environment, Non-Tuberculous Mycobacteria (NTM) are opportunistic pathogens that can cause chronic pulmonary diseases. M.abscessus and M.avium complex are the most frequently encountered species in pulmonary infections. Associated with progressive lung damage, M.abscessus is also the most drug-resistant mycobacterium, extremely challenging to treat.(1)

In patients suffering from Cystic Fibrosis, Chronic Obstructive Pulmonary Disease or Bronchiectasis, accurate diagnosis of NTM infection is essential to help clinicians target the right treatment and implement appropriate measures. Annual screening is now highly recommended, and regular follow-up is needed in positive cases.(2)

Designed for selective culture of NTM, the NTM Elite agar plate is the industrial version of the RGM medium. It enables easier and improved diagnosis compared to commonly used Acid-Fast Bacilli (AFB) culture media.

 

Improved workflow and accuracy

  • No prior decontamination needed
  • High selectivity: 85.6% versus 18.6%* 
  • Drastically improved fertility: 95% versus 40%*
  •  Incubation at 30°C enhances growth of NTM without allowing growth of BSL3** mycobacteria
  • Usable in routine BSL2** microbiology laboratories

 

* compared to AFB reference method: Lowenstein Jensen medium associated with MGIT medium

** BSL: BioSafety Level
