Mycobacterium fortuitum is commonly found in which location?

Mycobacterium fortuitum is a type of non-tuberculous mycobacteria that is commonly found in environmental sources, particularly in water supplies. Tap water serves as a significant reservoir for this bacterium. Its presence in tap water can be attributed to its natural habitat, including soil and water in various environments.

When considering the context of this organism and its implications in infections, it is important to recognize that while it can be found in contaminated surfaces or surgical instruments, those are not its primary sources. The ability of Mycobacterium fortuitum to exist in water supplies makes tap water the most accurate choice when identifying where this bacterium is commonly found.
