Signs and Symptoms

The symptoms associated with nontuberculous mycobacteria (NTM) infections depend on which part(s) of the body are involved. Pulmonary infections may cause TB-like symptoms, including:

  • Chronic cough, sometimes with bloody sputum
  • Fever
  • Chills
  • Weight loss
  • Weakness

Skin-related NTM infections may cause persistent sores, boils, ulcers, and granulomas that do not respond to routine antibiotics. Those affecting lymph nodes may cause inflammation in the node.

All of these symptoms may also be seen in a variety of other conditions. The diagnosis of most NTM infections depends on the positive identification of mycobacteria in body fluids or tissues.
