  • You have not had TB treatment before, and your chest X-ray or CT scan does not show signs of previous TB.
  • You are willing to have a research bronchoscopy (a procedure to look inside the airways) at the start of the study, at 6 months, and at 18 months, and you expect to stay in the local area for the full study period.
  • If you are HIV-positive, you have been stable on HIV treatment (ART) for at least one year.
  • You are able and willing to come back for follow-up visits and do not plan to move away in the near future.

  • Your TB is resistant to the antibiotic Rifampicin.

  • You have TB affecting both lungs extensively.
  • You have taken probiotics, antibiotics, or inhaled steroids within the last three months (this does not apply to "sick control" participants).
