Mycobacterium intracellulare

Mycobacterium intracellulare is a type of bacteria that belongs to the Mycobacterium avium complex (MAC). It naturally lives in soil, water, and dust. In some cases, it can cause lung infections, especially in people with weakened immune systems or pre-existing lung conditions, leading to symptoms like coughing, fatigue, and weight loss. These infections are typically diagnosed through specialized tests and treated with a combination of antibiotics over several months. While generally not contagious between people, understanding and managing exposure can help prevent infection in vulnerable individuals.
