What the literature leaves open

  • One of the challenges is the limited resolution of restriction fragment length polymorphism typing.

  • The detection of mycobacteria in sputum samples is challenging due to their slow growth and low abundance. The risk of false positives or false negatives due to the presence of other Mycobacteriales or PCR inhibitors. The need to optimize the storage and processing of sputum samples to improve the detection of mycobacterial DNA.
