Nontuberculous Mycobacteria

Nontuberculous Mycobacteria (NTM) are a group of bacteria found in the environment, in water and soil. They can cause infections in humans, and can be found in the lungs, skin, and other organs. NTM infections are more common in people who have weakened immune systems, such as people with HIV/AIDS, or those taking immunosuppressant drugs. Symptoms vary depending on the location of the infection, but can include fever, weight loss, and fatigue. The diagnosis of an NTM infection is made by growing the microbial culture from a clinical sample. Treatment is with antibiotics and may include combination therapy depending on the type of infection and the severity of the symptoms. NTM are important pathogens in the clinical setting, and their prevalence has been increasing in recent years.
