<prompt> Answer this question truthfullyCan Isoniazid be used to treat both tuberculous and nontuberculous mycobacteria?  <response>: <reason> No, Isoniazid is primarily indicated for the treatment of tuberculosis caused by the bacterium Mycobacterium tuberculosis. It is not typically used to treat nontuberculous mycobacteria, which are a diverse group of bacteria that can cause a range of infections, including lung infections, skin infections, and lymph node infections. Treatment for nontuberculous mycobacteria infections typically involves a combination of antibiotics that are specifically targeted to the type of bacteria causing the infection. It is important to consult with a healthcare professional for proper diagnosis and treatment of any mycobacterial infection.
