Mycobacterial Infections

Mycobacterial Infections

Nontuberculous mycobacteria  (NTM) are a group of mycobacteria other than Mycobacterium tuberculosis and Mycobacterium leprae. NTM can cause a range of infections, affecting the lungs, skin, soft tissues, and other organs. Unlike TB, NTM infections are not transmitted from person to person and are often associated with environmental exposure. Pulmonary NTM infections typically present with symptoms similar to TB, including chronic cough, fatigue, and weight loss. Skin and soft tissue infections may manifest as nodules, abscesses, or ulcers. Individuals with compromised immune systems, such as those with HIV/AIDS or underlying lung diseases, are at an increased risk of NTM infections. Diagnosis involves a combination of clinical evaluation, imaging studies, and microbiological testing, often requiring specialized techniques for NTM identification. Treatment is challenging due to the inherent resistance of many NTM species to standard anti-TB drugs. Management may involve a combination of antibiotics, and the duration of treatment can be prolonged. Research in mycobacterial infections continues to focus on developing new diagnostic tools, more effective treatments, and understanding the complex host-pathogen interactions. Global efforts to control TB include vaccination strategies (Bacillus Calmette-Guérin or BCG vaccine), improved case detection, and treatment programs. NTM infections, being less well understood, require further research to elucidate optimal diagnostic and therapeutic approaches, especially given their increasing recognition as significant contributors to pulmonary and extrapulmonary diseases.
